About
SpaceXAI builds the Grok family of frontier models, known for strong reasoning performance and a distinct personality, and — since acquiring Cursor (Anysphere) — the most widely used AI code editor and Composer, its coding model tuned for speed inside the agent loop.
On Brainbase, Grok models are platform-billed and run inside any open harness — OpenCode or Qwen Code — selected per task like any other platform model.
The Cursor CLI runs as a native harness: bring your Cursor API key, and turns are served by Composer and billed to your Cursor account — no platform model routing involved.
Available on Brainbase:
- Grok: SpaceXAI's frontier reasoning line, with 500k tokens of context, including Grok 4.6, Grok 4.5
- Composer: Cursor's frontier coding model, native to its agent, including Composer 2.5
Run these models in Cursor CLI, Codex, OpenCode, or Qwen Code — selected per task like any other platform model.
