Nex-N2.5 is an agentic model built to turn goals into working, verified outcomes. Its core strength is agentic coding within a visual feedback loop: it can explore codebases, implement multi-file changes, run commands, launch applications, interact with browser and desktop interfaces, and test software from the user's perspective. When observed behavior does not match the intended result, Nex-N2.5 can diagnose the issue, revise its implementation, and test again. This makes it especially effective for autonomous software engineering, GUI-based QA, computer-use automation, deep research, and scientific workflows where success must be demonstrated in the environment, not merely inferred from generated code.

Throughput is how fast the model writes (tokens per second, higher is better). Time to first token is how long before the answer starts (lower is better).
Share of requests served without a server error. Client errors (4xx) do not count.
Works with the OpenAI SDK pointed at our base URL. Every parameter is in the API reference.

On NagaAI, Nex-N2.5-Pro costs $0.0375 per 1M input tokens and $0.125 per 1M output tokens. You pay only for what you use, with no subscription.
Nex-N2.5-Pro reads up to 262.1k tokens in one request, counting the prompt and the answer together.
Yes. Nex-N2.5-Pro can call your functions as tools and can answer in a JSON schema you give it.
It takes text and images as input and returns text.
