Why we're meaningfully cheaper.
We aggregate demand across thousands of teams, then negotiate or source bulk credits from verified partners. You see one clean invoice.
- Bulk-tier provider credits
Direct partnerships with select frontier providers and verified resellers — at volumes individual startups cannot reach.
- Open-weight model arbitrage
For Llama, Mistral, Qwen and DeepSeek we route to the cheapest healthy host (Groq, Together, Fireworks, AWS).
- Smart caching & batching
Semantic cache hits, request deduplication, and Anthropic batch API routing reduce cost up to a further 70%.
"We replaced four provider integrations with a single Blue Box endpoint. Our infra bill dropped 41% and our on-call rotation got way quieter."
Ship AI faster, cheaper, with one API.
Three plans — Pro, Scale, and Enterprise — built for teams of any size.
