Pygar contains model-provider integrations for Anthropic, OpenAI, Google and xAI. A request may use different configured providers for classification, panel reasoning, synthesis or resilience fallback; not every provider processes every request.

The provider used depends on the reasoning model selected for the run, the role being performed, service availability and the platform's current configuration. This article describes the implemented routing capability; it does not assert that every integration is enabled in every environment.
