Originally created by @kim-gtek on GitHub (Nov 21, 2024).

I noticed that OPENWEBUI takes 2-4 seconds longer to load chats.

By looking at the logs, the problem is clear, before every chat OPENWEBUI calls

get_all_models()

I have fixed this issue by adding the environment variables:
backend/open_webui/config.py
Line 533:

ALL_MODELS_CACHE_TTL = "1800"
OPENAI_MODELS_CACHE_TTL = "1800"
OLLAMA_MODELS_CACHE_TTL = "1800"

These are imported into the following files:

backend/open_webui/apps/main.py
Line 1007:

@cached(ttl=MODELS_CACHE_TTL) # Cache variable to control get_all_models()
async def get_all_models():

backend/open_webui/apps/ollama/main.py
Line 260:

@cached(ttl=OLLAMA_MODELS_CACHE_TTL)
async def get_all_models():

backend/open_webui/apps/openai/main.py
Line 372:

@cached(ttl=OPENAI_MODELS_CACHE_TTL)
async def get_all_models() -> dict[str, list]:

Obviously importing from aiocache import cached to each file, and adding the corresponding environment variable to from open_webui.config import (
