Questions about this entry
Short answers drawn from the linked project or page.
Clone the repo, run uv sync to install pinned dependencies, export TYPESAFE_API_KEY with a key from the TypeSafe console, then run uv run jupyter lab notebooks/. The notebooks also read the key from a .env file.
No. Every notebook ships with its outputs saved, so the full workshop, including real API responses, can be read on GitHub without a key or any calls.
A full top-to-bottom run of all five notebooks costs under one cent. Jev is priced at $0.042 per million input tokens with output free, and the porch example used 1,229 input tokens for about $0.00005.
TOP-25-USE-CASES.md is a grouped top-25 with article links, and JEV-USE-CASES-WILD.md catalogs 82 verified real-world builds with a live-build shortlist and a sources section.
Only model_router.py, which uses Jev to pick a model and then calls OpenAI, so it needs OPENAI_API_KEY. The other projects, including the tool firewall and RAG reranker, run on Jev.
None. It covers what a model is, how RLHF works step by step, why RLVR produces reasoning models, and how RLCD rewards honest probabilities, with two audience quiz slides built in.
Jev takes a state, any text or JSON, plus typed questions and returns typed answers with calibrated probabilities in about 100 ms. Jev makes the decision and your code owns the action.
