Could you build this?
Partial While wrapping LLM APIs with structured schemas is straightforward, extracting calibrated probability distributions across dozens of categories with high accuracy requires logit extraction and calibration techniques.
What it would actually take: The stack consists of a Node/TypeScript SDK and server interfacing with Ollama, vLLM, or OpenAI-compatible backends. The difficult aspect is probability calibration: querying model token logits directly (via top_logprobs), computing softmax across multi-token class labels, and applying temperature scaling or Platt scaling to ensure returned confidence numbers are mathematically calibrated. It requires familiarity with NLP classification evaluation, logit probability extraction, and calibration metrics (ECE).
