17,000+ LLMs Now Available on Backboard

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.
