Accept turns on our own product analytics and lets the daily.dev ad pixel report to daily.dev; Decline keeps both off. The Reddit ad pixel runs either way, on our public pages and when you sign up or buy, to measure our ads. The daily.dev pixel loads on our public pages and at sign-up too, but reports nothing unless you accept. Ad pixels may set their own cookies and never see your chats. See our Privacy Policy.

Changelog

Model changes

When a model leaves Vani Chat or the Vani API, we list it here: when it happened, why, and what to use instead. We also mark notable new models. Newest first; dates are in UTC.

  1. Retired

    • Kimi K3.1 Pro Derisked · Moonshot AI

      moonshotai/kimi-k3.1-pro-derisked

      Use instead: GLM 5.3 Derisked

    Removed from Vani Chat and the Vani API, a day after it launched. API requests that name it are refused. GLM 5.3 Derisked remains available.

  2. New model

    • Kimi K3.1 Pro Derisked · Moonshot AI

      moonshotai/kimi-k3.1-pro-derisked

    Kimi K3.1 Pro with the refusal layer removed, running on Vani's own servers. For adults (18+): in Vani Chat on Plus and higher, and on the Vani API.

  3. Temporarily unavailable

    Our provider stopped serving these two models (Kimi K2.7 Code on 4 November, MiMo V2.5 on 20 October), so every request failed. Failed requests were never charged. We've hidden both in Vani Chat and the API, and will bring them back if they are served again.

  4. Removed from the API

    • Seedream 4.0 · ByteDance

      bytedance/jimeng-image-4.0

    Removed from the Vani API because it could not be served reliably there. It is still available in Vani Chat and Studio.
