Prompt Caching With Provider Native Support

via “prompt-caching-with-provider-native-support”

Unified API for 100+ LLM providers — OpenAI format, load balancing, spend tracking, proxy server.

Unique: Automatically detects provider support for prompt caching and applies cache_control headers without code changes. Tracks cache_creation_input_tokens and cache_read_input_tokens from provider responses to calculate cost savings. Supports both system prompt caching (for consistent instructions) and context caching (for large documents).

vs others: Automatic detection vs manual cache_control header management; transparent cost savings tracking vs manual calculation; works across multiple providers vs provider-specific implementations
