Anthropic marketing (and even supposedly technical write ups) sadly has become more hyperbole and less substance over time imo. This technology is so impressive on its own, really feels like shootings themselves in the foot in the long run, but what do I know

Case in point here where they conveniently fail to report the false positive rate, while also saying that if it wasn’t for Address Sanitizer discarding all the false positives this system would have been next to useless

But on the other hand the claude app is garbage… https://github.com/anthropics/claude-code/issues/22543 obviously native apps can be garbage too, but I must say electron apps have a surprisingly high incidence of terrible performance issues, unsure if it’s a correlation or causation issue

LangGraph implements a variant of the Pregel/BSP algorithm for orchestrating workflows with cycles (ie. not DAGs) and parallelism without data races. You can design your graph as a state machine if you so desire

Hi do you mind sharing more what you mean by "the api makes excessive calls"?

Hi, you don't have to use langchain tools or ToolNode with langgraph, you can absolutely write your custom tool handling logic. In langgraph nodes are just functions that can do whatever you want, seems to be some misconception somewhere?

FWIW we have first class support for subgraphs in the library, would love to know what issues you faced there. Support for subgraphs in the studio is coming soon.

A topological sort can't be used for graphs with cycles

Fwiw we didn't start with Pregel, but instead reached for it when we saw issues (described elsewhere in this thread) with the previous approach

The value of using pregel is supporting cyclical graphs, with concurrent tasks, but completely deterministic behavior (eg. doesn't matter that task A this time happens to finish before task B, its results will be applied in a predetermined order, etc)

Pregel actually doesn't require the structure of the graph to be declared ahead of time, the next set of tasks (functions) to run is computed at the beginning of each step, so in theory the graph topology could be entirely dynamic. Langgraph supports dynamic topologies too, ie. don't declare any hard edges, add a conditional edge after every node

I'm one of the authors so my opinion would be biased ha

Langgraph is not a no-code tool for visual programming, it's an implementation of the Pregel algorithm for execution of cyclical computation graphs (ie not DAGs)
