Changelog Entry

Description

When a model declares capabilities.memory: true in its meta config, memory tools (add_memory, search_memories, etc.) should be registered for execution. Without this fix, models with native function calling and memory capability enter a 30-iteration tool retry loop because add_memory appears in the tool schema but isn't in the execution dict.

Root Cause

get_builtin_tools() in utils/tools.py only checked features.get("memory") (per-chat toggle sent by frontend). This could be False even when:

  • The admin memory setting is enabled
  • The model explicitly declares capabilities.memory: true
  • The frontend sends features.memory: true for some chats but not others

This is inconsistent with how other capabilities like web_search and image_generation are handled elsewhere in the codebase.

Changed

  • backend/open_webui/utils/tools.py: get_builtin_tools() now also checks get_model_capability("memory", False) as a fallback when features.get("memory") is not set

Steps to Reproduce (Before Fix)

  1. Configure a model with capabilities.memory: true and function_calling: native
  2. Ensure admin memory setting is ON
  3. Send "Remember my favorite color is blue"
  4. Model calls add_memory but tool is not in execution dict → empty result → 30-iteration retry loop

Steps to Verify (After Fix)

  1. Same config as above
  2. Send "Remember my favorite color is blue" → single add_memory call → DB row created
  3. New chat → "What is my favorite color?" → search_memories → correct recall

Fixes #22666
