Nuno CamposandGitHub 4fb2aeacc7 Add checkpoint_during arg (#4169) 
- This provides a new mode of execution where only the last checkpoint
is saved
- We save the last checkpoint no matter how the agent run is terminated
(success, error, interrupt, etc)
- This cuts down on cpu time spent on checkpointing, while not losing
any resilience benefits, given individual task writes are still saved
- If an error occurs and the run is retried, any tasks that completed
successfully before will be skipped (as currently)
- checkpoint_during=True is useful when you want to time-travel to inner
steps of a run
- The default value will remain the current behavior, ie.
checkpoint_during=True

William FHandGitHub c5b118a672 Add admonitions about managed checkpointers (#4197) 
If you're deploying with langgraph API, you don't need to manually
define a checkpointer. For folks who already know they'll be developing
with the api server, I'd like to save everyone time by making this more
clear in the docs on checkpointing.

Eugene YurtsevandGitHub adac016e33 cli: support dict format for graph specification in langgraph.json (#4164) 
Allow the CLI to work with dict format for the graph specification.

```json
{
  "dependencies": ["./my_agent"],
  "graphs": {
    "agent": {
      "path": "./my_agent/agent.py:graph",
      "description": "this is my agent description"
    }
  },
  "env": ".env"
}
```

And backwards compatible with:

```json
{
  "dependencies": ["./my_agent"],
  "graphs": {
    "agent": "./my_agent/agent.py:graph",
  },
  "env": ".env"
}
```

from langchain_core.messages import BaseMessage
from langchain_openai import ChatOpenAI
from langgraph.graph import StateGraph
from langgraph.graph.message import add_messages

from langgraph.graph.ui import AnyUIMessage, ui_message_reducer, push_ui_message


class AgentState(TypedDict):  # noqa: D101
    messages: Annotated[Sequence[BaseMessage], add_messages]
    ui: Annotated[Sequence[AnyUIMessage], ui_message_reducer]


async def agent(state: AgentState):  # noqa: D103
    message = await ChatOpenAI(model="gpt-4o-mini", temperature=0).ainvoke(
        state["messages"]
    )

    # Also directly writes the message to `ui`
    push_ui_message("simple", {"hello": "123"}, message=message, state_key="ui")

    return {"messages": [message]}
