I was intrigued by Jev and the self-hostable projects appearing around it, such as OpenJev and SemIf . Reading about them introduced me to a neat trick: reading an LLM's token probabilities. Apparently this is an old trick for some people. See e.g. OpenAI's logprobs cookbook . But it was new to me. I believe the basic idea is to write a prompt like this: State: My order arrived broken and I want a refund. Question: Which team should handle this? [A] billing [B] shipping [C] returns Answer with the letter of the best option only. Then add a few JSON request parameters to a compatible Chat Completions request: { "max_completion_tokens": 1, "logprobs": true, "top_logprobs": 20 } The LLM API will return the letter plus the model's log probabilities for alternative tokens. Repeat for each question. Forcing it to generating only one token avoids a lengthy answer and is super quick, though processing the input still costs time.…
