📄 Description

This change adds a new environment variable called OLLAMA_KEEP_ALIVE which sets how long a model will be loaded into memory. It uses the same semantics as the keep_alive parameter in the generate, chat, and embeddings API calls, namely:

  • if set to a positive value, it will default to whatever time was set
  • if set to zero it will unload immediately after generation
  • if set to a negative value it will remain in memory

You can either use a value in seconds (e.g. OLLAMA_KEEP_ALIVE=60 for 60 seconds), or as a duration string (e.g. OLLAMA_KEEP_ALIVE=10m).

This change works with both the API, and with the REPL.

Fixes #2508
