Strengths and weaknesses
Jev
- Returns typed values and probabilities, so there is no prose to parse and no retry logic
- Roughly 70-500ms end to end, with questions in one request evaluated in parallel
- $0.042 per million input tokens with free output, far below frontier LLM rates for classification
- Confidence values let code act automatically, queue for review, or escalate
- Available through OpenRouter, Cloudflare Workers AI, Vercel AI Gateway, Netlify and LangChain
- Generates no text at all: no replies, summaries, code or explanations
- Text input only; no image, audio or video support
- It can only choose from an answer space you define, so it cannot surface a category you did not list
- 64k tokens per request, with 32k for state plus the longest question, rules out very long documents
- Calibration holds across batches, not individual answers, so high-stakes decisions still need review
