Type-Safe Streaming & Invoke

LangGraph 1.1 introduces version="v2" — a new opt-in streaming format that brings full type safety to stream(), astream(), invoke(), and ainvoke().

What's changing

v1 (default, unchanged): stream() yields bare tuples like (stream_mode, data) or just data. invoke() returns a plain dict. Interrupts are mixed into the output dict under "__interrupt__".

v2 (opt-in): stream() yields strongly-typed StreamPart dicts with type, ns, data, and (for values) interrupts fields. invoke() returns a GraphOutput object with .value and .interrupts attributes. When your state schema is a Pydantic model or dataclass, outputs are automatically coerced to the correct type.

invoke() / ainvoke() with version="v2"

from langgraph.types import GraphOutput
result = graph.invoke({"input": "hello"}, version="v2")
result is a GraphOutput, not a dict
assert isinstance(result, GraphOutput)
result.value       # your output — dict, Pydantic model, or dataclass
result.interrupts  # tuple[Interrupt, ...], empty if none occurred

With a non-"values" stream mode, invoke(..., stream_mode="updates", version="v2") returns list[StreamPart] instead of list[tuple].

stream() / astream() with version="v2"

for part in graph.stream({"input": "hello"}, version="v2"):
    if part["type"] == "values":
        part["data"]        # OutputT — full state
        part["interrupts"]  # tuple[Interrupt, ...]
    elif part["type"] == "updates":
        part["data"]        # dict[str, Any]
    elif part["type"] == "messages":
        part["data"]        # tuple[BaseMessage, dict]
</tr></table>
