I agree with this post.

Otherwise the larger picture is that MCP is a land grab for building an eco-system around integrations to get access to data. Your LLM agent is not valuable if it can't access things for you... and from a market perspective enterprise pays a lot for this stuff already, and yes MCP is not thought out at all for Enterprise really... At least thankfully they added stateless connections to the spec...

Unfortunately their blog doesn't have the example they have on x.com - https://x.com/ZyphraAI/status/1888996367923888341 - which I think is more illustrative.

your comment made me think I read it wrong, but it's not closed source, they're just moving to a source available license...

yep, agreed. I think that's another way to view the current state of "GenAI" tooling (e.g. all those complicated frameworks that received $M in funding) and why things like https://www.anthropic.com/research/building-effective-agents fall on deaf ears...

+1 for vanilla code without LangChain.

Interesting! I feel like this is a cross between https://github.com/dagworks-inc/burr (switch state for context) and https://github.com/Netflix/metaflow because the output of the "task" declares its next hop...

The challenge with this approach though is that you need to run the actual code to see what it does, or as a developer build up a mental model of the code ... but it does shine in certain use cases -- and also reminds me of https://github.com/insitro/redun because it takes this approach too.

New comment by krawczstef in "Show HN: Modeling parallel (and hierarchical) agents with Burr"

krawczstef — Thu, 21 Nov 2024 17:50:20 +0000

Forgot to mention, on the roadmap we have pluggable executors, e.g. delegating parallelism to whole agents/subgraphs to systems like "ray". Would love to collaborate with folks if that's interesting.

Show HN: Modeling parallel (and hierarchical) agents with Burr

krawczstef — Thu, 21 Nov 2024 14:46:08 +0000

Hi all, just showing a new construct in Burr (for more info on Burr see - https://news.ycombinator.com/item?id=39917364) for modeling agent / agentic parallelism. We think a "graph" mental model lends itself well to thinking about parallelism (& hierarchy) -- would love your thoughts.

Video walkthrough of notebook - https://youtu.be/G7lw63IBSmY

Why did we build this feature? The future is only going to get more complex with LLMs & agents, and having the right constructs with integrated observability will help us get there. We naturally saw people doing this and thought we could help simplify it more.

Key Features of Burr's constructs:

* you can map over dynamic values in state (e.g. run an agent in parallel over many URLs)

* you can map over dynamic actions/or sub-graphs (e.g. running different agents in parallel)

* you can do the cartesian product between the two (e.g. run over prompts and actions/agents and do it in a loop to modify them...)

More details here - https://burr.dagworks.io/concepts/parallelism/.

Things not mentioned but useful in this parallel context, Burr comes with pluggable durability/persistence/memory (see https://burr.dagworks.io/concepts/state-persistence/).

We'd love to get any early feedback from the HN community, ideas for where you'd like the framework to go, or UI/UX experiences in this space. We will be in the comments for the next few hours to respond! Or leave an issue or discussion here - https://github.com/dagworks-inc/burr. Thanks!

Looks great. But being burned by other "abstractions", e.g. LangChain, I'm weary of the oversimplification. How are you not going to make those same mistakes?

@staranjeet we should get you plugged in as part of persistence with https://github.com/dagworks-inc/burr !

krawczstef — Wed, 04 Sep 2024 00:11:22 +0000

Yep. When I was designing https://github.com/dagworks-inc/hamilton part of the idea was to make it easy to understand what and where. That is, enable one to grep for function definitions and their downstream use easily, and where people can't screw this up. You'd be surprised how easy it is to make a code base where grep doesn't help you all that much (at least in the python data transform world) ...

Wow. Implemented pregel to run a 3 node graph... Jokes aside, that's an interesting thesis to have in there...

krawczstef — Fri, 09 Aug 2024 18:23:24 +0000

Really? Can you point to code for that? To me it's just a way to describe a graph and execute it, exactly like https://github.com/dagworks-inc/burr (I'm an author).

Here's a blog post that I just pushed that doesn't use them at all - https://blog.dagworks.io/p/building-a-conversational-graphdb (we have more on our blog - search for RAG).

[disclaimer I created Hamilton & Burr - both whitebox frameworks] See https://www.reddit.com/r/LocalLLaMA/comments/1d4p1t6/comment... for comment about Burr.

getting into enterprise is hard, so probably trying open source to help with that.
