Sites that watch the AI field itself and publish a continuously refreshed number from that watching: release timelines, independent benchmarks, open datasets, composite rankings, preference arenas, and usage statistics.
The category's dividing line is what the number measures, since each member answers a different question about the same field.

- [AI Release Tracker](ai-release-tracker/index.md) - a free, ad-free timeline of frontier releases since ChatGPT, with launch-day scores and flat-file exports for agents.
- [Artificial Analysis](artificial-analysis/index.md) - independent quality, price, and speed measurement across 671 models, 100+ providers, and the chips underneath.
- [Epoch AI](epoch-ai/index.md) - the research nonprofit's open datasets and trend series on models, compute, data centers, and AI's trajectory.
- [LLM Stats](llm-stats/index.md) - a conservative composite leaderboard over 398 models with the category's only MCP server for agents.
- [LMArena](lmarena/index.md) - blind human-vote arenas ranking models by preference, the field's most cited and most gamed signal.
- [OpenRouter Rankings](openrouter-rankings/index.md) - real token spend through the OpenRouter gateway, CC BY licensed, the category's only revealed-preference number.

Its members are compared on shared rows in the [Trackers and Leaderboards Feature Matrix](trackers-and-leaderboards-feature-matrix/index.md).
