Anthropic
Anthropic powers Jorv Builder's brain — the Claude model that reads your project, plans the work, and drives the conversation in the cockpit. Claude Opus (1M context) is the default.
Anthropic is required. Without an Anthropic key, the brain has nothing to run on. Other providers (OpenAI, Gemini, Ollama) are supplementary, used for drones, audits, and voice.
What Jorv Builder does with Anthropic
- Streams brain responses for the main Orbit chat
- Calls Claude with the project's PRODUCT.md / ARCHITECTURE.md bound as files (via the Files API for caching)
- Uses
messages.stream()with prompt caching breakpoints to minimise token spend across the session - Sends tool-use requests to Anthropic for every action Orbit takes (read_file, write_file, run_command, etc.)
Setup
- Get a key at console.anthropic.com.
- Settings → AI Models → Anthropic → paste → Test.
Cost expectations
- Brain (Opus): ~$15 / Mtok input, ~$75 / Mtok output (before cache discounts).
- Cache hits drop input cost by 90% — typical sessions hit the cache heavily after the first few turns.
- Daily spend for moderate use: typically $1–$5.
The cockpit's costs panel breaks down spend per session and per day.
