Nimbus-2 · long-horizon reasoning is live

Generative intelligence for the AGI era

Nimbus-2 plans, codes, and ships. One API call streams production-grade answers, decisions, and code at 842 tokens per second.

Demo: the Nimbus API streams a summarized code review in real time.

Built for builders

Everything you need to ship generative features — nothing you don't.

Long-horizon reasoning

A 1M-token context window with chain-of-thought planning that stays on task across entire codebases.

Developer-first API

Typed SDKs for Python, Go, and TypeScript, structured JSON outputs, and token-level streaming by default.

Aligned by design

Constitutional guardrails, automatic PII redaction, and full audit logs on every single request.

How it works

From API key to production in three steps.

01

Get an API key

Create a workspace, grab a key, and pick the model that fits your latency budget.

02

Send a prompt

POST JSON to /v1/chat with tools, schemas, and system instructions attached.

03

Stream tokens

Token-level SSE streams land in your app with a sub-200ms time-to-first-token.

Frequently asked questions

What is Nimbus-2?

Nimbus-2 is our frontier generative model: a 1M-token, tool-using reasoner tuned for coding, analysis, and long-horizon planning tasks.

How does pricing work?

You pay per token, never per seat. The Developer tier includes 1M free tokens each month; Scale adds priority routing and an SLA.

Is my data used for training?

No. API inputs and outputs are never used to train our models, and a zero-retention mode is available on every plan.
