9 of 9 models operational
Every model NovaRouter routes to, with the state that decides whether a request to it is accepted. A disabled model stays listed rather than disappearing — a 503 you can explain beats a 404 you cannot.

No availability history
NovaRouter does not probe upstreams on a schedule, so there is no uptime percentage to report — health is discovered when a request fails and moves to the next candidate in that model's chain. Every attempt is recorded against the request it belongs to, so failover is visible per request on your own usage page. Earlier versions of this page showed a 90-day uptime figure that was never measured; it has been removed rather than estimated.
6 publishers, one wire format
Every model in the catalogue answers the same OpenAI-compatible request. Each alias carries an ordered chain of upstreams, and a rate limit or 5xx from one moves to the next without a retry in your code.
Anthropic
us-east • us-west • eu-central
Fable and Claude, with the longest context windows in the catalogue and the strongest agentic coding scores.
OpenAI
us-east • eu-west • apac
GPT with broad general capability, native structured output and audio input.
us-central • eu-west • apac
Gemini, with a two-million-token context window and native multimodal input across text, image and audio.
DeepSeek
apac • us-west
Open-weight reasoning models priced near the floor, strongest on mathematics and competitive programming.
xAI
us-central • eu-west
Grok with fast reasoning over a wide context window and real-time knowledge access.
Z.ai
apac • us-west
Open-weight GLM served at the lowest cost per token, plus the catalogue's embedding model.

How routing works
- Ordered chains per model
Every alias declares its upstream candidates in order. Position 0 is tried first.
- Failover without a retry in your code
A rate limit, timeout or 5xx moves to the next candidate. A malformed request stops immediately — replaying it would fail identically.
- Bounded, then honest
One chain walk is bounded end to end. If no candidate answers, the response is a 503 that says so rather than a hung connection.
Each attempt is recorded against the request, so a completion that took three tries is visible as three attempts rather than as one slow call.
Only the attempt that succeeded contributes tokens to your usage record — a request nobody could serve records none at all.
