 Another approach involves LLM-based function calls, where LLM decides if a specific function should be invoked based on the conversation's status during each inference. This approach enables dynamic multi-agent conversations, as seen in scenarios like [multi-user math problem solving scenario](https://github.com/microsoft/autogen/blob/main/notebook/agentchat_two_users.ipynb), where a student assistant automatically seeks expertise via function calls.
 
-### LLM Caching
-
-Since version 0.2.8, a configurable context manager allows you to easily
-configure LLM cache, using either DiskCache or Redis. All agents inside the
-context manager will use the same cache.
-
-```python
-from autogen import Cache
-
-# Use Redis as cache
-with Cache.redis(redis_url="redis://localhost:6379/0") as cache:
-    user.initiate_chat(assistant, message=coding_task, cache=cache)
-
-# Use DiskCache as cache
-with Cache.disk() as cache:
-    user.initiate_chat(assistant, message=coding_task, cache=cache)
-```
-
-You can vary the `cache_seed` parameter to get different LLM output while
-still using cache.
-
-```python
-# Setting the cache_seed to 1 will use a different cache from the default one
-# and you will see different output.
-with Cache.disk(cache_seed=1) as cache:
-    user.initiate_chat(assistant, message=coding_task, cache=cache)
-```
-
-By default DiskCache uses `.cache` for storage. To change the cache directory,
-set `cache_path_root`:
-
-```python
-with Cache.disk(cache_path_root="/tmp/autogen_cache") as cache:
-    user.initiate_chat(assistant, message=coding_task, cache=cache)
-```
-
-For backward compatibility, DiskCache is on by default with `cache_seed` set to 41.
-To disable caching completely, set `cache_seed` to `None` in the `llm_config` of the agent.
-
-```python
-assistant = AssistantAgent(
-    "coding_agent",
-    llm_config={
-        "cache_seed": None,
-        "config_list": OAI_CONFIG_LIST,
-        "max_tokens": 1024,
-    },
-)
