Using GPT-3.5 Turbo 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-3.5 Turbo does the answering when Jev sends it work, or when you name it yourself. At list price GPT-3.5 Turbo falls in the llm11-balanced band, but no pack routes to it because its context window is under 32K tokens, the floor for pack members. You can still pin it: pass openai/gpt-3.5-turbo as model and routing steps aside while verification still runs.
Jev is new, so we have not published results for GPT-3.5 Turbo 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 | $0.00055 | $0.550 |
| Question over retrieved documents | 4,000 / 500 | $0.00275 | $2.75 |
| Long document summary | 30,000 / 1,000 | $0.017 | $16.50 |
