Sources and licenses

Where every number and headline on this site comes from, what we're allowed to do with it, and when it was last updated. If a source is unavailable, we keep showing its last good data and say so.

Epoch AI Benchmarking Hub

Used for
Benchmarks: the Epoch Capabilities Index and 5 benchmarks Epoch runs itself.
Data
Downloadable CSV archive, updated daily by Epoch.
License
CC BY 4.0. Epoch: "free to use, distribute, and reproduce provided the source and authors are credited." Benchmark data Epoch collects from other projects keeps its original license, so we don't include it.
Credit
Epoch AI, ‘Capabilities & benchmarking’. Published online at epoch.ai. Retrieved from https://epoch.ai/benchmarks.
Our copy
benchmarks.json (the subset we show, same license).

OpenRouter Models API

Used for
Free models and the homepage highlights.
What we take
Model metadata only: name, provider, date added, context length, price and the free flag, from the public models endpoint.
Terms
OpenRouter Terms of Service. Credited as "Model list and prices: OpenRouter". We don't republish the raw file.
Not used
The optional benchmark scores in OpenRouter's data come from Artificial Analysis, whose terms don't allow republishing them. We leave them out.

News feeds

We show the headline, source, date and link only. No article text or images. Each feed's terms were checked before adding it.

Considered and left out for now: feeds whose site terms prohibit automated collection or data extraction (for example the OpenAI, NVIDIA and AWS sites), and vendors without a public feed.

Update schedule

A script fetches every source once a day (11:17 UTC), checks the data, and proposes the update for review. Nothing goes live until a person approves it. If a source fails, its last good data stays up with its original date.

Snapshots in this build: benchmarks 270 models, OpenRouter 468 models, news 80 headlines.
