/ 01

OpenAI-compatible

Drop-in replacement for the OpenAI SDK.

Same endpoints, same request/response shape. Point your existing client at api.brainstormrouter.com — no code change beyond the base URL.

/ 02

Thompson-sampling routing

Cost × latency × quality, optimized continuously.

Provider mix optimized by observed signals — cost, latency, quality benchmarks. Per-tenant routing weights can be locked or learned.

/ 03

Audit-grade logs

Every request, replayable.

Request logged with provider chosen, prompt hash, response hash, billing line. Replayable end-to-end for compliance + debugging.

/ 04

Providers

7 providers, growing.

Anthropic (Claude), OpenAI (GPT), Google (Gemini), xAI (Grok), Mistral, Perplexity, DeepSeek + open-weights. New providers added without API changes.

/ 05

Tenant isolation

RLS on the audit log.

Per-tenant API keys. Cross-tenant analytics architecturally impossible. Enterprise tenants can export their full audit chain.
