Jev vs frontier LLMsLIVE DEMO

Same input, same decision — two very different bills

Pick a model and a use case, run a decision, and watch how a chat-shaped LLM and TypeSafe AI's Jev handle the exact same call. Simulated for clarity — timing and reasoning text are representative, cost is computed live from each vendor's published price per token.

    Simulated for illustration — reasoning text, timing, and token counts are representative, not live API calls. Cost is calculated from each vendor's published input-token rate (output tokens are typically priced higher, so this understates the real gap). Jev's per-decision figures are TypeSafe AI's own published benchmark; independent evals aren't out yet. Full sourcing: cost-comparison.html.
