Concurrency Support

Concurrency Support

Ollama is designed to handle multiple requests concurrently, allowing you to serve several clients or processes at once. By default, the Ollama server runs as a long-lived process and accepts parallel HTTP requests over its OpenAI-compatible API endpoints (e.g., /v1/chat/completions).

Key concurrency features:

• Each request spawns its own model evaluation stream

• Server manages batching and queuing under the hood for fair scheduling

• Safe to send simultaneous requests from different threads, processes, or machines

• Built-in load balancing across multiple Ollama instances
