Flint is hosted by a single provider through OpenRouter, carries a 262,144-token context window, supports tool calling and JSON output via response_format without JSON-schema enforcement, and is offered free with rate limits.

It is suited for investigating codebases, fixing bugs, implementing features, and writing tests.\n\nThis model is hosted by one provider. OpenRouter forwards every request to it directly — no routing decisions to make.\n\nPerformance\n\nThroughput is how fast the model writes (tokens per second — higher is better). Latency is total round-trip time (lower is better). TTFT is time-to-first-token — how long before you see anything appear (lower is better).\n\nUptime\n\nUptime is the percentage of the past 3 days that at least one provider was responding to requests. Availability is the percentage of time that inference was successfully served. OpenRouter continuously monitors and uses the next-best provider when one returns an error.\n\nApps\n\nPublic apps that send the most traffic to this model. Good signal for what real production workloads look like — and a hint at which use cases this model is best suited for.\n\nActivity\n\nToken volume and request traffic to this model over time.\n\nAPI\n\nDrop-in code to call this model. OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. The only thing that changes between models is the model slug below.\n\nUptime (3d)The model was reachable.

You can access per-provider uptime data programmatically through the Endpoints API.
