Arena AI: The Official AI Ranking & LLM Leaderboard
Arena AI / LMArena (community; originated from UC Berkeley SkyLab and LMSYS)
Community-driven platform to chat, compare, vote on, and rank LLMs, image, code, and multimodal models via real-world evaluations.
Key features
- Multi-Model Chat Interface: Allows users to open interactive chat sessions with many public and anonymous models to directly compare conversational behavior and outputs.
- Crowdsourced Pairwise Voting: Collects human judgments via side-by-side comparisons and votes to measure which model outputs are preferred in realistic prompts, feeding into ranking calculations.
- ELO-Based Ranking (Arena-Rank): Converts aggregated pairwise votes into stable ELO-like scores with confidence intervals and variance estimates, enabling fair ranking across many models and runs.
- Category-Specific Leaderboards: Publishes separate, filterable leaderboards for Text/Chat, Code, Vision, Image Generation, Video, Document understanding, Search, and related categories to surface top performers per task.
- Open Data Snapshots & API: Provides daily auto-updated JSON snapshots, a REST API (free, no auth in third-party mirrors), and downloadable datasets for reproducible analysis and historical tracking.
- Integration Ecosystem: Works with community tools and repositories (GitHub, Hugging Face Spaces) and offers tooling like arena-rank (pip package) to reproduce ranking methodology and build custom leaderboards.
- Transparent Metadata & Traces: Exposes per-run metadata, vote counts, confidence intervals, and example conversations so researchers can audit judgments and reproduce evaluations.
- Public web interface for chatting with multiple models and comparing responses side-by-side
- Head-to-head voting system enabling human preference judgments
- ELO-style ranking methodology (Arena-Rank) with confidence intervals and variance metrics
- Category-specific leaderboards: text/chat, code generation, vision/multimodal, image-gen, video, document/search, etc.
- Daily snapshots and historical tracking of leaderboard data (JSON snapshots per date and category)
- Open data exports and unified JSON schema for leaderboard files
- Ecosystem tooling: arena-rank Python package, GitHub exports, Hugging Face datasets and Spaces
- Integrations via third-party REST endpoints and community-provided APIs/clients (raw GitHub JSON, REST wrappers)
- Extensible UI built with modern web frameworks (community projects indicate Svelte frontend) and browser extensions/scripts that enhance functionality
- Self-hostable / reproducible components and examples (open-source repos, schemas, examples)
Best for
- Model selection for product teams: Compare candidate LLMs across real user prompts and leaderboards to pick the best model for chat, coding, or multimodal features.

- Open reproducible evaluations: Engineers and auditors download daily JSON snapshots or use the arena-rank library to reproduce leaderboard computations and verify rankings or experiments.
- Community-driven model vetting: Model authors and community members submit models and prompts to gather broad human preference feedback and discover failure modes or strengths.
- Integrating ranking data into tooling: Data analysts and devs consume the REST API or GitHub JSON snapshots to build dashboards, cost-effectiveness comparisons, or automated model-selection pipelines.
- Benchmarking multimodal capabilities: Teams compare image, video, and code-generation models on task-specific leaderboards to identify top performers for specialized workflows.
- Compare and rank LLMs and multimodal models for selection and procurement decisions
- Collect human preference data and crowd-sourced evaluations for model research
- Integrate leaderboard snapshots into analytics dashboards or cost-effectiveness tools
- Export structured benchmark data for offline analysis, reproducible research, or model tracking
- Provide demo/chat endpoints for stakeholders to interactively test model behavior
- Build custom tooling around Arena data (scripts, exporters, UI unlockers, Chrome extensions)
