Using GPT-6.1 Sol 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. GPT-6.1 Sol does the answering when Jev sends it work, or when you name it yourself. GPT-6.1 Sol falls in the llm11-balanced band, and the labs and limits it meets make it eligible for that pack. Packs keep a spread of eight models per band, and it is not one of the eight today, so it is only picked when you name it in a custom pool.
Jev is new, so we have not published results for GPT-6.1 Sol 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.

|---|---|---|---|
| Short chat turn | 500 / 200 | $0.00300 | $3.00 |
| Question over retrieved documents | 4,000 / 500 | $0.013 | $13.00 |

Packs keep a spread of eight models per band, and it is not one of the eight today, so it is only picked when you name it in a custom pool. Routing decisions are made by Jev, TypeSafe AI's System One model.
- Is GPT-6.1 Sol a System One model?
- No. GPT-6.1 Sol 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 GPT-6.1 Sol cost?
- $2.00 per million input tokens and $10 per million output tokens. A 4,000 token prompt with a 500 token answer costs about $0.013, so a thousand of them is about $13.00. llm11 passes provider list price through and charges 5% when you buy credits.
- What is the GPT-6.1 Sol context window?
- 1,050,000 tokens, with up to 128,000 tokens in a single reply.
- Does GPT-6.1 Sol support tool calling and structured output?
- The catalogue lists tool calling, structured output and reasoning controls.
- Can I use GPT-6.1 Sol through llm11?
- Yes. Set model to openai/gpt-6.1-sol on the OpenAI-compatible endpoint and the request goes to it directly, with verification still running.
- Does Jev route to GPT-6.1 Sol?
- Routing decisions are made by Jev, TypeSafe AI's System One model. GPT-6.1 Sol falls in the llm11-balanced band, and the labs and limits it meets make it eligible for that pack. Packs keep a spread of eight models per band, and it is not one of the eight today, so it is only picked when you name it in a custom pool.
