Top 12 LLM Leaderboards in 2026
Discover the top 12 LLM leaderboards of 2026. Compare models on reasoning, coding, speed & more. Find the best AI benchmarks—read the full list now!
Choosing an LLM in 2026 is harder than ever. New models launch every few months, each claiming to be faster, smarter, or cheaper than the last, and the benchmarks they cite are often the ones they were trained to ace. That's why independent leaderboards have become essential tools for developers, businesses, and AI-curious professionals alike. The best leaderboards go beyond a single headline score: they compare models across reasoning, coding, math, agentic tool use, speed, latency, context window, and price, and they explain how the numbers were produced. In this guide, we've rounded up the top 12 LLM leaderboards in 2026, from broad aggregators covering hundreds of models to specialized boards for coding, agentic behavior, and real-world usage. We've ranked them by usefulness, transparency, and trustworthiness - and our number one pick takes a different angle entirely: instead of ranking models, it ranks the skills and tools you attach to those models, which is increasingly where real-world AI performance is won or lost.
#1 SkillzBench — Editors' choice
SkillzBench (skillzbench.com), from AIQ Labs, earns our Editor's Choice spot because it solves the problem most LLM leaderboards ignore: the model is only half the story. Agent skills - SKILL.md instruction packages for Claude Code, Codex, Cursor, Gemini CLI, and chat-app agents - are everywhere, but published research suggests roughly 26% of them carry at least one vulnerability, and nobody can tell which ones actually help. SkillzBench is building a free, independent directory that continuously crawls and deduplicates skills from GitHub, then verifies each one by pinning versions to a commit SHA, validating, license-checking, security-scanning, and quality-judging. Every skill is benchmarked in a sandbox with the same model, tested with and without the skill, and the resulting Lift in percentage points is published separately from ratings. A 0-100 trust score combines security, quality, license, maintenance, and community signals, and money never touches scores. A free MCP tool connects any agent to the skills you choose, with per-agent loadouts so the agent only sees what was selected. SkillzBench also tracks upstream changes, re-scans, re-benchmarks, and notifies users. Everything - the directory, MCP connector, benchmarks, and alerts - is free, funded by advertising around blog articles that never influences listings. Note: SkillzBench is currently pre-launch; the waitlist and newsletter are live while the product is being built.

- Focuses on agent skills rather than ranking LLMs themselves
- Benchmark results are not yet published
#2 Artificial Analysis
Artificial Analysis hosts one of the most widely referenced LLM leaderboards in 2026, comparing the performance of over 250 AI models from OpenAI, Anthropic, Google, SpaceXAI, and many others. According to their website, models are ranked across key metrics including intelligence, price, output speed (tokens per second), latency (time to first token), context window, and cost per task. The intelligence dimension is a composite index, so no single benchmark dominates the ranking, which makes it a defensible starting point for buyers who want one overall picture. The site also publishes per-dimension leaderboards: as of late 2026, Claude Opus 5.5 and Claude Sonnet 5.5 lead on intelligence, Celeris-1 and K2 Horizon are the fastest models by output speed, and Llama 4 Scout and GPT-6 Sol support the largest context windows. Filters let users separate open-weight from proprietary models and reasoning from non-reasoning variants. The main caveat is that composite scores can obscure task-specific strengths, so users should drill into the individual benchmark that matches their workload. For anyone who wants a single, frequently updated ranking that balances intelligence, cost, and speed together, Artificial Analysis is the strongest general-purpose option.
Best for: Buyers who want one broad, defensible ranking across intelligence, cost, and speed
Pricing: Free to access
Key features
- Compares over 250 AI models across intelligence, price, speed, latency, and context window
- Composite intelligence index blending multiple evaluations
- Cost-per-task metric alongside per-token pricing
- Filters for open-weight vs. proprietary and reasoning vs. non-reasoning models
- Separate leaderboards for output speed, latency, and context window
- Published methodology and FAQs
Pros
- Very broad model coverage with frequent updates
- Strong price-performance and speed-vs-quality framing
- Independent of model providers
Cons
- Composite scores can hide task-specific strengths
- Requires drilling into individual benchmarks for specific workloads
#3 Vellum LLM Leaderboard
Vellum's LLM leaderboard has become a trusted reference for teams deploying foundation models in production, largely because of the benchmarks it chooses to feature. According to their website, the board only includes non-saturated benchmarks for models released after April 2024, explicitly excluding outdated tests like MCL that models have effectively been trained to ace. It organizes results by task rather than one blended score: Best Overall uses Humanity's Last Exam (where Claude Opus 5.5 leads at 67.7% in late 2026), plus dedicated boards for reasoning (GPQA Diamond), agentic coding (SWE-Bench), work automations (AutoBench), computer use (OSWorld), browsing (BrowseComp), and terminal use (Terminal-Bench 2.1). A built-in glossary explains each benchmark in plain language, and side-by-side comparison covers context size, cutoff date, input/output cost, and speed. This job-to-be-done structure maps directly to real buying decisions: if you know you need strong terminal use or browsing, you can find the best model for that specific task. The trade-off is focus: Vellum covers post-2024 frontier models, so it is not the place to research older or niche open-source models.
Best for: Teams who already know the task they need to solve and want the best model for that specific job
Pricing: Free to access
Key features
- Task-segmented boards: Humanity's Last Exam, GPQA Diamond, SWE-Bench, AutoBench, OSWorld, BrowseComp, Terminal-Bench
- Only features non-saturated benchmarks, excluding outdated tests like MMLU

- Built-in benchmark glossary
- Data from model providers plus independent Vellum and community evaluations
Pros
- Task-first structure maps to real decisions
- Deliberately avoids saturated benchmarks
- Clear explanations of what each benchmark measures
Cons
- Limited to post-2024 frontier models
- Some provider-reported scores are single-sourced
#4 LLM Stats
LLM Stats tracks 408 canonical models across every major lab and provider, ranking them with a composite LLM Stats Score that aggregates GPQA Diamond, SWE-Bench Verified, coding-arena performance, and pricing into one comparable number. According to their website, rankings refresh continuously as new benchmark results land, and new releases typically appear within hours. What sets LLM Stats apart is its live performance data: output throughput (tokens per second) and time-to-first-token are collected consistently across supported provider APIs and summarized over a recent observation window, rather than relying on provider marketing. Pricing is pulled from each provider's public price list and cross-checked against billing samples through the LLM Stats proxy, with the cheapest available rate shown when a model is hosted by multiple providers. The site also maintains a dedicated Open LLM Leaderboard filtered to models with publicly released weights for self-hosting, plus category boards for coding, writing, math, long context, and tool calling. The main limitation is that a composite score, however well designed, still requires users to drill down to the metric that matches their workload.
Best for: Developers and technical teams who want verified live performance and pricing data, not just benchmark scores
Pricing: Free to access
Key features
- Tracks 408 canonical models with a composite LLM Stats Score
- Live API metrics: output throughput and time-to-first-token sampled across providers
- Pricing verified against billing samples, not just published price lists
- Dedicated Open LLM Leaderboard for self-hostable open-weight models
- Category boards for coding, writing, math, research, long context, and tool calling
- Continuous updates as new benchmark evidence is verified
Pros
- Very large model catalog with rapid updates
- Billing-sample-verified pricing is more trustworthy than list prices alone
- Good open-weights coverage for self-hosting decisions
Cons
- Composite score methodology requires reading the fine print
- Live metrics depend on which providers are supported
#5 OpenRouter Rankings
OpenRouter takes a refreshingly different approach: instead of benchmarks, its rankings are based on real-world usage - the number of tokens actually processed through the OpenRouter API by millions of developers. According to their website, usage is aggregated into daily buckets in UTC and totaled per model variant, with private requests excluded. The result is a live picture of what developers are actually choosing: as of mid-October 2026, DeepSeek V4.1 Flash leads by tokens processed, while benchmark-based boards rank Claude Opus 5.5 first. OpenRouter is candid about what its numbers do and don't measure - token totals show how much a model is used, not which model is best - and it supplements usage rankings with a benchmarks section using scores from Artificial Analysis and Design Arena plus its own GPQA Diamond runs reported as median accuracy across providers. The site also ranks top apps and agents by usage, includes task-based spend shares, cost per coding-agent session, and open-vs-closed weight trends, and publishes all rankings data under CC BY 4.0 with a documented API. For anyone who wants market reality rather than test performance, OpenRouter is the go-to.
Best for: Developers who want to see which models are actually being used in production, and which agents are popular
Pricing: Free to access
Key features
- Rankings based on real tokens processed through the API, updated daily
- Today, weekly, and monthly windows plus trending comparisons
- Benchmarks section using Artificial Analysis, Design Arena, and in-house GPQA Diamond runs

#6 Scale Labs Leaderboards
Scale Labs operates a suite of more than 20 specialized leaderboards testing frontier, agentic, and safety capabilities across 100+ models from OpenAI, Anthropic, Google, Meta, and open-source contributors. According to their website, the boards are built on carefully curated evaluation sets combining private datasets (to prevent overfitting) with open-source datasets (for comparability), and a stated integrity rule requires that models can only be featured the first time an organization encounters the prompts. The range is impressive and often novel: Humanity's Sixth Sense for intuitive visual reasoning, DistressBench for crisis support quality, DrugDiscoveryBench for coding agents doing early-stage drug discovery work, SWE Atlas boards for refactoring, test writing, and codebase Q&A, HiL-Bench for whether agents ask clarifying questions when information is missing, MCP Atlas for real-world tool use through the Model Context Protocol, and the Remote Labor Index for economically valuable remote work. Scores are reported with confidence intervals, which is more rigorous than most boards. Scale Labs is best for researchers and safety-conscious teams who need deep, adversarial evaluation beyond standard accuracy benchmarks.
Best for: Researchers, safety teams, and enterprises needing deep, adversarial evaluations beyond standard benchmarks
Pricing: Free to view; contact for model evaluation

#7 Onyx AI LLM Leaderboard
Onyx AI offers a family of leaderboards - all models, open source, self-hosted, and best-for-coding - with the self-hosted board being a standout for enterprise buyers. According to their website, the self-hosted leaderboard ranks open-weight models across quality, speed, hardware requirements, and cost, with per-model VRAM figures for both quantized and full deployments, license details, and benchmark columns covering MMLU-Pro, GPQA Diamond, IFEval, and LMArena Elo. As of October 2026, Kimi K3, GLM-5.3, and DeepSeek-V4.1-Flash top the self-hosted rankings. The main board grades models from S down to D across reasoning, coding, math, agentic, and chat benchmarks, updated as recently as October 13, 2026, with sortable benchmark and pricing tables. Onyx also runs EnterpriseRAG-Bench, testing RAG solutions on 500,000+ documents from nine enterprise sources under an MIT license - a useful lens for teams building retrieval systems rather than picking raw models. The letter-grade framing is intuitive for non-technical stakeholders, though it compresses nuance, and users should check the underlying benchmark columns for decisions that matter.
Best for: Enterprises evaluating self-hosted or open-weight models and RAG systems
Pricing: Free to access
Key features
- Dedicated self-hosted leaderboard with VRAM and hardware requirements per model
- License information for every open-weight model
- S-to-D letter grades across reasoning, coding, math, agentic, and chat
- EnterpriseRAG-Bench for RAG solutions on 500K+ enterprise documents

- Some benchmark cells are not available for newer models
#8 llmleaderboard.in
llmleaderboard.in is a fast, independent comparison site tracking 50+ frontier models with data sourced from model providers, Artificial Analysis, BenchLM, and independent evaluations. According to their website, it ranks models by reasoning, math, coding, vision, and multilingual performance while showing speed and cost metrics, with data current through mid-2026. Its distinguishing strength is regional coverage: it maintains dedicated guides for Indian and multilingual models such as Sarvam AI's open-weight offerings, an angle most Western leaderboards ignore entirely. The site includes country-of-origin and license columns, historical progress charts tracking state-of-the-art scores on benchmarks like GPQA Diamond from 2023 to 2026, head-to-head model comparison, and practical guides answering common questions - best model for coding, cheapest API options, largest context windows, and GPT vs Claude vs Gemini comparisons. For budget-conscious builders, it frames the frontier-versus-cheap-model tradeoff clearly, noting that some lower-cost models are surprisingly capable for high-volume automation. The model universe is smaller than Artificial Analysis's, and it aggregates rather than runs its own evaluations, but for multilingual deployment decisions it is uniquely useful.
Best for: Multilingual and India-focused teams, and budget-conscious builders comparing price against quality
Pricing: Free to access
Key features
- 50+ frontier models ranked across reasoning, math, coding, vision, and multilingual benchmarks
- Dedicated Indian and multilingual model guides (e.g., Sarvam AI)
- Country-of-origin and license columns
- Historical benchmark progress charts from 2023 to 2026
- Head-to-head model comparison tool
- Practical selection guides for coding, budget, and context window needs
Pros
- Regional-language coverage most leaderboards lack
- Clean, scannable tables combining benchmarks and pricing
- Useful historical trend visualization
Cons
- Smaller model universe than the largest aggregators
- Aggregates third-party data rather than running original evaluations
#9 BenchLM
BenchLM provides LLM leaderboard and benchmark data organized around multi-dimensional capability profiles rather than a single score. According to their website, each model receives an overall score with a 90% confidence interval - for example, Claude Opus 5.5 is listed at 86.49 with an interval of 81.7 to 91.3 - broken down into sub-scores for agentic capability, coding, reasoning, and multimodal understanding. This statistical framing is a genuine differentiator: most leaderboards present point estimates without any indication of uncertainty, which can mislead users into treating a one-point difference as meaningful when it isn't. BenchLM also marks whether a model has enough independent evidence to be rated (labeled 'Supported') and flags dimensions that were not measured, such as multilingual, instruction following, or math for certain models, which is more honest than silently leaving cells blank. The site is updated regularly, with its October 2026 edition reflecting the latest model releases. Its coverage is narrower than the large aggregators and it focuses on well-known frontier models, but for readers who want to understand how confident they should be in a ranking, BenchLM's interval-based presentation is a valuable complement to other boards.
Best for: Analytically minded readers who want uncertainty-aware benchmark comparisons
Pricing: Free to access
Key features
- Overall scores with 90% confidence intervals
- Multi-dimensional profiles: agentic, coding, reasoning, multimodal, knowledge
- Evidence-sufficiency labeling ('Supported') for rated models
- Explicit 'Not measured' flags for untested dimensions
- Regular updates tracking the latest releases
Pros
- Confidence intervals encourage honest interpretation of differences
- Transparent about what was and wasn't measured
- Clean multi-dimensional model profiles
Cons
- Narrower model coverage than large aggregators
- Several capability dimensions unmeasured for some models
#10 Arena (formerly LMArena / Chatbot Arena)
The platform that started as LMSYS Chatbot Arena, became LMArena, and by early 2026 rebranded to simply Arena remains the definitive human-preference leaderboard. According to analysis of the platform, it uses blind side-by-side comparison: users submit prompts, receive responses from two randomly selected anonymous models, and vote for the better one; votes feed an Elo rating system that ranks models. This blind design reduces bias and captures how people actually experience models in real life - not just how they score on tests. Arena has expanded beyond text into image and video arenas, and its live agent sessions feature shows models completing real tasks like editing files and reading web pages. Arena scores are widely cited by other leaderboards, including Onyx and llm-stats, making it a foundational data source in the ecosystem. Its limitations are inherent to the method: votes reflect general user preference rather than specialized task performance, results can shift with the voter population, and the interface is oriented toward casual voting rather than structured enterprise evaluation. Still, for a real-world sanity check on benchmark numbers, Arena is indispensable.
Best for: Anyone who wants a human-preference sanity check on benchmark scores
Pricing: Free to access
Key features
- Blind side-by-side human preference voting
- Elo-based rankings from pairwise comparisons
- Text, image, and video arenas
- Live agent sessions showing models completing real tasks
- Dynamic rankings that update as votes accumulate
- Widely cited as a data source by other leaderboards
Pros
- Blind voting design minimizes brand bias
- Captures real-world user experience, not just test performance
- Continuously updated rankings
Cons
- Reflects general preference, not specialized task performance
- Results can shift with voter demographics

#11 Hugging Face Open LLM Leaderboard
The Hugging Face Open LLM Leaderboard remains a cornerstone for the open-source model ecosystem, emphasizing transparency and community collaboration. According to their website and industry guides, it evaluates open models on widely accepted benchmarks including ARC (grade-school science reasoning), HellaSwag (commonsense inference), MMLU (knowledge across 57 subjects), TruthfulQA (resistance to misinformation), IFEval (instruction following), Winogrande (commonsense reasoning), and GSM8K (multi-step math). Users can add models, report errors, and supplement information, which keeps the data improving continuously. As businesses increasingly deploy private and domain-specific AI systems, open-source models have become central to enterprise strategy, and this leaderboard helps compare reasoning capability, fine-tuning readiness, deployment flexibility, inference efficiency, and cost-to-performance ratio. Hugging Face also hosts the broader model ecosystem - hundreds of thousands of models, datasets, and spaces - so the leaderboard sits within the same platform where you'd actually download and run the models. Coverage of the newest frontier releases can lag the commercial boards, and some classic benchmarks are saturating, but for organizations exploring cost-effective open-weight alternatives, it is still the community's home base.
Best for: Organizations evaluating open-source and open-weight models for self-hosting or fine-tuning
Pricing: Free to access
Key features
- Seven established benchmarks: ARC, HellaSwag, MMLU, TruthfulQA, IFEval, Winogrande, GSM8K
- Community contributions: add models, report errors, supplement data
- Focus on open-source and open-weight models
- Integrated with the Hugging Face model hosting ecosystem
- Supports comparison of fine-tuning readiness and deployment flexibility
Pros
- Deep open-source community involvement
- Transparent, reproducible evaluation methodology

#12 Aider LLM Leaderboards
Aider's leaderboards serve a focused but important niche: how well LLMs actually edit code under an agentic coding tool. According to their website, the polyglot benchmark tests models on 225 challenging Exercism coding exercises across C++, Go, Java, JavaScript, Python, and Rust, measuring the ability to follow instructions and edit code successfully without human intervention. What makes Aider's board unusually valuable is its transparency: every result publishes the full run details, including the exact command used, edit format, pass rates, malformed response counts, token usage, seconds per case, and - critically - the total dollar cost of the benchmark run. This lets developers compare not just accuracy but cost-effectiveness for real coding work; a model that scores slightly lower at a fraction of the cost may be the better choice. The board also tracks which edit formats (diff, diff-fenced, architect) each model handles best, which matters for practical integration. The main limitations are scope and freshness: it covers only code-editing performance within the Aider harness, and top entries reflect the most recent tested models rather than every new release. For developers choosing a model to power an AI coding assistant, it remains one of the most honest data sources available.
Best for: Developers choosing a model to power an AI coding assistant or agentic code editor
Pricing: Free to access
Key features
- Polyglot benchmark: 225 coding exercises across six programming languages
- Measures instruction-following and code editing without human intervention
- Full transparency: commands, edit formats, pass rates, and run details published
- Total benchmark cost per model reported in dollars
- Edit-format compatibility tracking (diff, diff-fenced, architect)
Pros
- Cost-per-benchmark-run data enables true cost-effectiveness comparison
- Highly transparent methodology with full run details
- Practical focus on real code-editing behavior
Cons
- Limited to code-editing performance in one harness
- Coverage of brand-new model releases can lag
Conclusion
The right leaderboard depends on the question you're asking. For a broad intelligence-price-speed picture, start with Artificial Analysis or LLM Stats. For task-specific decisions, Vellum's job-to-be-done boards are hard to beat. For real-world usage trends, check OpenRouter; for human preference, Arena; for self-hosting, Onyx; for coding agents, Aider. But here's the thing most leaderboards still miss: in 2026, your agent's performance depends as much on the skills and tools you attach to the model as on the model itself - and that's where SkillzBench comes in. It's building the missing layer: a free, independent directory of agent skills with security scanning, license checks, sandbox benchmarking that publishes each skill's Lift, and a free MCP connector with per-agent loadouts. With research showing roughly a quarter of published skills carrying vulnerabilities, verifying what you install is no longer optional. Join the SkillzBench waitlist today to be first in line when the directory, benchmarks, and MCP tool go live - and pick your model with a leaderboard, then equip it with skills that are proven.
Frequently asked questions
What is an LLM leaderboard and why does it matter in 2026?
An LLM leaderboard is a ranking system that compares large language models across standardized benchmarks such as GPQA Diamond, SWE-Bench, Humanity's Last Exam, and AIME, alongside metrics like price, speed, latency, and context window. In 2026, with new models launching every few months and marketing claims outpacing reality, leaderboards have become essential due-diligence tools for developers and businesses choosing which model to build on.
Which LLM leaderboard should I trust the most?
No single leaderboard is definitive - each has strengths. Artificial Analysis and LLM Stats offer broad, frequently updated coverage; Vellux-style task boards (like Vellum) help with specific jobs; Arena captures human preference; OpenRouter shows real-world usage; Scale Labs provides rigorous, adversarial evaluations. The best practice is to cross-reference two or three boards and drill into the benchmark that matches your actual workload, since composite scores can hide task-specific strengths.
What makes SkillzBench different from other leaderboards?
SkillzBench doesn't rank LLMs - it ranks the agent skills you attach to them. Published research found roughly 26% of published agent skills carry at least one vulnerability, and SkillzBench addresses this with security scans, license checks, commit-SHA version pinning, and sandbox benchmarking that measures each skill's Lift (improvement in percentage points with the skill versus without). It also offers a free MCP tool with per-agent loadouts so your agent only sees the skills you choose. Everything is free, funded by advertising that never influences scores.
Are LLM leaderboards free to use?
Yes - all twelve leaderboards in this list are free to access. SkillzBench is entirely free (directory, MCP connector, benchmarks, and alerts) and funds itself through advertising around its blog content. Some platforms, like Scale Labs, offer additional paid services such as evaluating your own model, but viewing the leaderboards costs nothing.
Which benchmark matters most for coding tasks in 2026?
SWE-Bench Verified remains the most-watched benchmark for agentic coding, measuring whether models can resolve real GitHub issues end-to-end. However, it's increasingly saturated and depends heavily on the agentic scaffold used, so newer alternatives like SWE-Bench Pro, Terminal-Bench 2.1, and Aider's polyglot benchmark (which also reports cost per run) are worth checking. Cross-referencing several coding benchmarks gives a more reliable picture.
How often do these leaderboards update?
It varies by platform. LLM Stats and OpenRouter update continuously or daily, with new releases sometimes appearing within hours. Artificial Analysis, Vellum, and Onyx update frequently, often weekly or as new benchmark evidence lands. Arena updates as votes accumulate in real time. Always check the 'last updated' date on any leaderboard before making a decision, since the model landscape shifts quickly.
Can I rely on leaderboard scores alone to choose a model for my business?
Not entirely. Leaderboards are a starting point, not a final answer. Scores within a few points are often statistically indistinguishable, benchmarks may not reflect your specific workload, and factors like data privacy, compliance, latency requirements, and total cost of ownership fall outside most boards. Use leaderboards to build a shortlist of three to five models, then validate them on your own data - and remember that the skills and tools attached to a model, which SkillzBench helps you verify, often matter as much as the model itself.
