FAQ

Frequently asked questions

Do I need a DeepSeek account to use DeepSeek in Aider?

No — one CompanyFabric key covers DeepSeek V4 and every other model in the library. Billing is one prepaid balance with exact per-call metering; BYOK at 0% is available if you already have provider keys.

What does DeepSeek V4 cost in Aider?

$0.3 / M input · $0.9 / M output — the same metered price as any other route to the model. Set a per-key budget cap to bound what the tool can spend.

Can I switch models later without touching Aider again?

Yes — the endpoint stays the same; the model is a string. Any catalog id works in the same configuration, including cheaper tiers for bulk work.
