Common questions

Do credits expire?

Top-up credits never expire. Subscription credits are granted on each paid billing period and behave like paid credits in your account.

Why are searches so cheap?

GPU Brain runs retrieval locally instead of calling a paid embedding API on every search, so the cost per lookup stays low.

What do subscriptions include?

Pro Monthly is $8 USD/month with 2,000 recurring credits. Pro Annual is $80 USD/year with 25,000 recurring credits. You can still buy top-up credits for heavier import or agent workloads.

Can I use GPU Brain as a Claude MCP tool?

Yes. Use the hosted MCP JSON-RPC endpoint at https://gpubrain.app.nz/mcp with a gb_... API key, or run gpubrain-cli mcp --api-url https://gpubrain.app.nz locally for stdio-based clients.

Can I self-host for free?

Absolutely. The full source is at github.com/codex-infinite/gpubrain. You need a Postgres server with the pgvector extension installed.

Will my integration break if you improve the search engine?

No. The REST, CLI, and MCP contracts are intentionally stable, so GPU Brain can improve retrieval under the hood without changing how your agents call memory.
