Use any arbitrary state graph or message graph with opengpts through the API server created by langchain-cli.

  • launched as a single docker compose
  • postgres database shared between langgraph api and opengpts backend (different schemas)
  • to add a custom graph you'd edit langgraph.json and point it to your custom graph, adding any needed dependencies

build:
context: backend
ports:
- "8100:8000" # Backend is accessible on localhost:8100
depends_on:
langserve:

Hi @nfcampos thanks greatly for your work on this branch with the new version of langgraph-cli. Just wonder if there is any plan to merge this new architecture into master for us to allow us better use or adapt to new backend? Thanks and happy to know any possible future plans for opengpts project!
