TIL people still fall for eh I mean use Langchain. Sorry, low value comment; I don’t know how to do that differently; it is such bad garbage since day one and strangely it did not improve. Sorry anyway for the comment, at least it was not LLM generated?
Yes, I also thought it's crap the moment I saw they need langchain to develop a harness.
The fact that Stripe are touting a production product that (at face value) benefits their business seems to suggest that maybe crap is subjective and as ever, being overly opinionated in an emerging space might actually be a blocking mindset rather than a positive one.
It might also suggest they went with the first LLM recommendation, like Anthropic choosing React for Claude Code.
To make your comment more high value, could you explain why you think langchain is bad?
It (and most other systems) abstract the wrong concepts when you want to create an agent. They promote what was likely never a great strategy but even parsimoniously what are strategies that were good ideas months or a year back.
For example how langchain or whatever else handles subagents and deep research is laughable even today.
So whats the recommendation? Just use pydantic and code everything up yourself. Maybe strands I dont know.
Which specific strategies do you think are outdated, and what would you recommend instead? This sounds more like a criticism of older versions of LangChain than its current APIs. The post also uses deepagents, a separate package in the same ecosystem. Is there something in the current implementation of either that you’re referring to?
Instead of spending half the comment reflecting on your post why not point out what you don’t like about it or some better alternatives?
I have a hard time keeping up with the space. Is langchain old news? Is there a page that kind of shows what the status quo for tooling is?
+1 would love to know as well. I have generally found the open source space to be lacking in this area and hoping it catches up!
There's like 1000 langchain alternatives and none are good, they're all vibe-coded unstable projects.
I use Apache Burr but it's not as good as LangChain. I just don't want to use software whose website has a pricing page if it's not a SAAS.
Totally, I find LangChain is the Vercel of ML
For what reasons?
It's a lot of sugar and high level abstractions on top of existing things, I find using the existing things not that complicated or difficult and I struggle to see the value on using the framework as it doesn't sit well with my way of abstracting the stack.
Ahhh I built an internal set of agents to run our company (finances, all info in the karpathy-style LLMWiki and a database of clients, contracts, billing, time tracking, all managed by MCPs, etc) and it's also called Kai (company name is Kaizen)
Happy to be in such good company!
All hand written or did you have any underlying libraries that you used?
But no darkmode support? … :D
I read a buzz word "Knowledge AI Platform" but I did not see any specific feature helpful for knowledge management like verification or transparency. It is more like any generic Agent builder. Maybe it meant to justify building something internally.
None of these have been especially impressive.
I think that’s because none of them go past “I’ve set up agents to be orchestrated this way” and that’s about as impressive as “look at my cloudformation template”.
This site could use a bit more line height, more paragraphs, or less text overall.
Somebody probably mentioned this already or maybe its just me but: The "endless scroll" this page does is neat, to say the least.-
I just hear Steve Ballmer yelling
[Bad mental image ... can't unsee ...] :)
Oldies let's gather here.
There's quite a bit of cool stuff in the console too! The one in the top right corner
oh not these guys again. These are just so idiotic.
Spotify built some nonsense like this too and made ridiculous claims that it saves 90 percent of tokens. I guess anything goes these days.
They don't really say why they built their own rather than using one of the open source solutions like https://github.com/bionic-gpt/bionic-gpt
Size and scale, I would think. An out of the box solution probably doesn't quite have the same capabilities as something they can (and now have to) manage in it's entirety.
Stripe probably WANTS to be opinionated about how their company works with the tools.
In the first paragraph:
so is it like CloudflareOS ? https://github.com/cloudflare/cloudflare-os
seems every company that has spare engineering resource all builds such thing internally
Dammit, I just named my newborn son Kai.
Very cool demonstration of managed agents built for the needs of their own business.
I think this is where a lot of companies are going to go: on-prem platforms that give various teams access to agents that are as powerful as coding agents, but much more managed and governed.
I'm betting on this with my open source project, Lightspeed: https://github.com/smartcomputer-ai/lightspeed
Your project seems way better than the stuff they built, nice work.
I like it, very smart for agents at scale.
Dang it, I just named my newborn son Kai. At least I didn’t go with Alexa..
It’s a cool name! Don’t let Stripe make you doubt that haha
The article reads like slop, to be honest.
It's very close to the direction we're taking for windmill.dev, we call it "operator builders" rather than focus on "knowledge graph" which the article is very light on details of.
What I'm mostly reading is a developer platform and runtime where users can build agents that can run tools and for that you need a secure code runtime, ACL/permissions, easy way to build apps or what cloudflare OS call gadgets. We're betting on this too at https://github.com/windmill-labs/windmill, very curious to see if that's the future for most enterprise and if a model where everyone vibe-code/fork cloudflare OS to their enterprise need is the future, or a more exhaustive/enterprise platform like ours does.
