Description

In new docs it is written that you can force tool call model_with_tools = model.bind_tools([tool_1], tool_choice="tool_1") but in v1 section it is written

# No longer supported
model_with_tools = ChatOpenAI().bind_tools([some_tool])
agent = create_agent(model_with_tools, tools=[])

# Use instead
agent = create_agent("openai:gpt-4o-mini", tools=[some_tool])

please address this issue and mention how to force tool call properly

Those docs refer to passing a pre-bound model into the create_agent factory. Forcing tool calls like you are used to in previous versions is still supported - https://docs.langchain.com/oss/python/langchain/models#forcing-tool-calls
