Every model release, on one timeline.

This page makes factual claims about other companies’ products, so it says how confident it is in each one rather than presenting everything with equal weight.

• Provider API means the entry, including its release date, was read straight from the lab’s own model-list endpoint.
• Official means it came from an announcement, model card, or changelog published by the lab.
• Unconfirmed means it is widely reported but has not been checked against a primary source yet. Those entries are marked on the model.

Benchmark figures are almost always self-reported by the lab that built the model, measured with its own harness. They are useful for tracking one lab’s progress over time and unreliable for ranking labs against each other, so each figure shows who ran it and when.

Where a release date could not be sourced, this page says so instead of guessing. Timeline generated 10 Sep 2026.
