Could you build this?
Partial A basic wrapper around open-weights LLMs for classification is straightforward, but implementing exact constrained logprob extraction and mathematical confidence calibration across diverse open models requires non-trivial inference engineering.
What it would actually take: Requires an inference server setup (vLLM, TGI, or llama.cpp) exposing token-level log probabilities, structured decoding engines (like Outlines or Guidance), and statistical temperature scaling/isotonic regression calibration modules. Vibe coders can handle the API interface, but low-level logprob extraction and calibration math require ML systems expertise.
