What's New
Backboard now gives developers access to 17,000+ LLMs through a single API — the largest model library available on any AI platform, enabling flexible, cost-efficient multi-model routing across all major providers.
Scale of Access
17,000+ models from OpenAI, Anthropic, Google, Meta, Mistral, Cohere, AI21, DeepSeek, and dozens more.
New models added automatically as providers release them — no SDK updates needed.
Unified model metadata — context window sizes, pricing, capabilities, and latency benchmarks for every model.
Intelligent Routing
Cost optimization: Route to the cheapest model that meets your quality threshold.
Latency optimization: Prefer faster models for real-time applications.
Capability matching: Automatically select models with required features (vision, function calling, JSON mode).
Fallback chains: Define ordered model preferences with automatic failover.
Context Window Management
Automatic detection of each model's context window size.
Adaptive truncation and summarization when switching between models mid-conversation.
No more silent context overflow — the system warns and adapts before tokens are lost.
How to Use It
Browse the Model Library in your dashboard or use the GET /v1/models endpoint to search and filter. Any model can be used by passing its ID to the model parameter in chat completions.
