Incorrect deprication instructions given for ChatOpenAI class

[lineality]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain_openai import ChatOpenAI

Error Message and Stack Trace (if applicable)

The problem is ~80 seconds of extreme CPU ramping lag, not an error message.

Description

An incorrect message may be printed to terminal:
"langchain_core/_api/deprecation.py:119: LangChainDeprecationWarning:
The class ChatOpenAI was deprecated in LangChain 0.0.10 and will be
removed in 0.3.0. An updated version of the class exists in the
langchain-openai package and should be used instead. To use it
run pip install -U langchain-openai
and import as from langchain_openai import ChatOpenAI."

when there is no actual problem, only the erronious deprication warning, the line
used in the code is:
from langchain_community.chat_models import ChatOpenAI

The warning says "from LangChain import ChatOpenAI" is deprecated, but that is
a non sequetor, as "from LangChain import ChatOpenAI" is NOT BEING USED.

And the above suggestion is broken: from langchain_openai import ChatOpenAI (DO NOT USE THIS)

Do NOT use this:
# from langchain_openai import ChatOpenAI # do NOT use this, it is broken or wrong or both
This causes a massive rampup in cpu usage for ~80-90 sec before completing the process.
This may not happen, or it may always happen, randomly, for the exact same task.

the working solution is:
from langchain_community.chat_models import ChatOpenAI # correct source

"langchain_community" is a correct source

from langchain_openai import ChatOpenAI is the way to use this

Do you have a flame chart for the "massive rampup in cpu usage"?
