Definition
The product page lists Jev at $42 per billion input tokens, described as a 238x lower input price than Claude Fable 5.1, and claims 193.6x faster and 444.6x cheaper than LLMs on its own System One workflows.
The caveat belongs with the number: these are vendor benchmarks from TypeSafe's own comparison, not independent testing. The independent picture lives in community benchmarks, field reports, and the recurring finding that question design dominates outcomes.
