Changelog

New models the day they ship, and everything else we changed, newest first.

  1. Claude Fable 5.1 and GPT-5.6 mini join the pool

    Both are routable today under prism/auto. Fable 5.1 lands at the top of the quality table for reasoning tasks; GPT-5.6 mini takes the fast tier's second slot behind Llama 4 Maverick.

  2. Per-key spend alerts

    Set a daily or monthly budget on any key and get an email or webhook at 50, 80 and 100 percent. Keys can now downgrade to the fast tier instead of hard-stopping when they hit the cap.

  3. Policies as files

    Routing policies can be committed to your repo as YAML and pushed with the CLI. The dashboard editor still works and writes the same format.

  4. Median overhead down to 38 ms

    The router now holds warm connections to every provider region and skips the scoring lookup for pinned models. p50 overhead dropped from 61 ms to 38 ms.

  5. EU data residency

    Team and Enterprise keys can be pinned to the Frankfurt region. Requests, logs and scoring samples never leave the EU.
