What we checked
Four different kinds of evidence, and what each one showed| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Not measured yet | we measured it |
| How its API is set up | A combination of settings no other listing in the catalogue uses | api_d34d4a9e |
| How much it can read and write | Reads up to 128,000 tokens at once, writes up to 50,000 | its own listing |
| Whether it thinks before answering | Reasons when asked to, at high, medium, low, none, medium by default | its own listing |
