Turning GLM-5.3-Flash into a Jev-like decision model
The authors demonstrate turning an off‑the‑shelf LLM (GLM‑5.3‑Flash) into a fast, typed decision model by prompting it to output only an option index and reading the token logits. Using vLLM’s allowed_token_ids and logprob_token_ids they achieve Jev‑level accuracy and speed, even for image inputs, without any fine‑tuning.
