multi-provider-ai-orchestration

Parse multiple keys from one field (comma or newline separated) and expand each into a separate failover node in the provider chain. When an error message contains 429, rate, quota, or limit, the logic continues to the next key of the same provider, then to the next provider.

Use group orchestration with three modes: parallel runs all models simultaneously via Promise.allSettled, pipeline feeds each node's output into the next with assigned roles, and synthesis collects parallel answers and merges them through a synthesizer model.

Yes, by chaining several free-tier providers ordered by tier and enabling failover. When one provider's limit is exhausted, requests automatically move to the next node, and local models like Ollama can serve as a final fallback tier.

Yes, users describe a provider with a JSON config containing a name and an http/https endpoint, plus an optional responsePath for extracting text. The system validates the config and builds the provider without using eval on arbitrary code.

Some providers accept Anthropic-format requests, so an existing Anthropic client works by only changing the base_url and API key. The dated model snapshot file lists which providers are currently compatible, such as DeepSeek's Anthropic endpoint.

Avoid it for simple single-provider API calls where only one model is involved, since the chain and failover logic add unnecessary complexity. It is designed for apps that need continuity across keys, providers, or cooperative multi-model workflows.
