Bring your own key
Anthropic · available now
On any paid tier, paste your own Anthropic API key in the brand
dropdown. Your dropdown shows ∞, and AI calls
run on your key — no meter, no Composure rate limits.
Composure validates the key with a tiny test call before saving
and keeps it scoped to your account. Remove it any time to fall
back to your subscription ink.
Coming after beta
Any major provider, plus local models.
Out of beta, you'll be able to bring an OpenAI, Google, or other
provider key — Composure will route each call to that provider's
tier-equivalent model (their Opus-class for deep reasoning, their
Sonnet-class for mid-weight, their Haiku-class for fast). You'll
also be able to point Composure at a local model (Ollama,
LM Studio) for fully self-hosted operation.
