Nox Vela 2.5 (New)

Everyday model · Released in Nox: November 9, 2026 · Page last updated: November 10, 2026

The fast everyday model on every plan — now reads images

Vela 2.5 is the everyday model of the Nox family and the default for everyday chat on every plan, including Free. It replaced Vela 2.1 in November 2026 and keeps the Vela line's headline property — speed — while reading photos directly instead of handing them to a separate vision model.

Vela 2.5 is the newest generation of Nox's fast models. It is powered by Claude Haiku 5.5, a model made by Anthropic and used through Anthropic's API; Nox runs its emergency check before every answer and sends the model Nox's own medical instructions and tools. It keeps replies quick and well organised, and it is the model everyday chat runs on by default.

It reads images natively: attach a photo — a label, a lab report, a screenshot — and Vela 2.5 reads it itself. Earlier Vela models were text-only and relied on a separate vision model for photos.

It carries the family's shared tools: inline charts, connected-app actions, and consent-gated live web access with cited sources.

Copy box: when a reply contains text you will paste somewhere else (a message to send, an email, a prompt, an answer for a form), Vela 2.5 puts just that text in its own box with a Copy button. One tap copies exactly what is in the box, and the explanation stays outside it.

Long conversations — requests over 100,000 tokens — are available on MAX and above. On other plans, Vela 2.5 covers everyday conversations of normal length.

Vela 2.5 is available on every plan, including Free, and is the active everyday model. Nox has not published benchmark results for Vela 2.5; earlier HealthBench figures shown elsewhere on this site belong to the models they name.
