Open full-size diagram: B.R.A.I.N. versus Gemini Gemini is a replaceable provider. It supplies reasoning, Live interaction, and embeddings; it does not own B.R.A.I.N. identity, canonical memory, beliefs, provenance, or source artifacts. Finalized transcripts, normalized events, session state, and usage estimates persist locally. Raw PCM is forwarded transiently and is not retained as durable audio. | Provider capability | Accepted configuration | | ------------------- | -------------------------------------- | | Live interaction | `gemini-3.1-flash-live-preview` | | Document embeddings | `gemini-embedding-2` at 768 dimensions | | Live guardrail | Accepted server default | | ------------------------ | ----------------------- | | Concurrent Live sessions | 1 | | Maximum session duration | 600 seconds | | Reconnects | 1 | | Daily audio allowance | 1,800 seconds | | Estimated daily cost cap | \$1.00 | These are fail-closed local guardrails. Provider billing remains authoritative. A missing provider secret fails closed; browser clients never receive it.
