[Question] consult about eino's functions

[h1ap]

I would like to consult about whether the functions of eino and langgraph are aligned, and if not, what are the differences in their features. Thank you.

Common core:

• both have component abstraction and implementations for LLM application development: ChatModel, Retrievers, Tool, etc.
• both have strong Graph orchestration capabilities: control flows, callbacks, checkpoint & interrupt.
• both have strong streaming support.

langgraph's strength:

• more feature complete in certain areas, such as memory components
• richer eco-system.

eino's strength:

• built-in type safety and performance built on strength of golang language, better for scaling
• more focused set of APIs and deeper functionality in certain areas, such as workflow API

EDIT: Is it the Checkpointer?

Hi, I'm on my phone now and so it's difficult to look through code.. if you don't mind me asking so naively.

I haven't seen any references to memory.. is there any sort of memory built in (whether abstractions or a simple message state that's always sent to the model).

[shentongmartin]

no built-in memory abstraction. They should be handled external to graph execution. However, the built-in state (and checkpoint) mechanism can be used to persist messages within a single graph run.
