Providers with known public APIs use their official endpoints: - meta-llama → api.llama.com/v1 - microsoft → models.inference.ai.azure.com (GitHub Models) - ibm-granite → us-south.ml.cloud.ibm.com/ml/v1 (watsonx) - tencent → api.hunyuan.cloud.tencent.com/v1 - morph → api.morphllm.com/v1 16 remaining providers without known public APIs route through OpenRouter (base_url = openrouter.ai/api/v1, OPENROUTER_API_KEY). sync-pricing.py updated with PROVIDER_API mapping.
Providers
LLM provider and model metadata for LibreFang. Each provider file defines the provider's API configuration and all available models with pricing, context windows, and capability flags.
