Using o1-pro with Jev
Jev is TypeSafe AI's System One model. It reads each request first and decides which model in your pool answers, with a calibrated confidence on that call. o1-pro does the answering when Jev sends it work, or when you name it yourself. o1-pro falls in the llm11-smart band, and the labs and limits it meets make it eligible for that pack. Today it is the most expensive model in that pack's live pool, which makes it the one a failed check escalates to.
Jev is new, so we have not published results for o1-pro with and without it, and this page does not invent any. Every response comes with a receipt that names the model that answered and what it cost against your most expensive model, so you can measure the pairing on your own traffic.
What a request costs
List price arithmetic, the same sum a receipt does. llm11 adds nothing per request; the only fee is on buying credits.
| Request | Tokens in / out | One | A thousand |
|---|---|---|---|
| Short chat turn | 500 / 200 | $0.195 | $195.00 |
| Question over retrieved documents | 4,000 / 500 | $0.900 | $900.00 |
| Long document summary | 30,000 / 1,000 | $5.10 | $5100.00 |

Same OpenAI request shape. Naming the model pins it, so nothing is routed, and the answer is still checked.

- Is o1-pro a System One model?
- No. o1-pro answers requests. The System One model is Jev, which decides which model answers each one, so the two do different jobs and llm11 uses both.
- How much does o1-pro cost?
- $150 per million input tokens and $600 per million output tokens. A 4,000 token prompt with a 500 token answer costs about $0.900, so a thousand of them is about $900.00. llm11 passes provider list price through and charges 5% when you buy credits.

- 200,000 tokens, with up to 100,000 tokens in a single reply.
- Does o1-pro support tool calling and structured output?
- The catalogue lists structured output and reasoning controls, but it does not list tool calling.
- Can I use o1-pro through llm11?
- Yes. Set model to openai/o1-pro on the OpenAI-compatible endpoint and the request goes to it directly, with verification still running.
