jev was really exciting to us since it’s a reprisal of how we think a lot of systems with AI should be built!
think about it this way: when starting a project you don’t start with big behemoth k8s clusters (à la frontier models/ harnesses), you start with smaller units (jev) and iterate as needed
we learned A LOT when simple decisions from LLMs were the paradigm (which is what langgraph was built around), to see this type of model stack rank next to models of today (*on subset of tasks) makes us really excited for the future

jev and langgraph are a great combo!
modeling agents as complex systems, with AI imbued in them, makes a ton of sense
langgraph is the best way to model them as such, and using Jev inside langgraph to turbo charge all the small decisions that need to be made is awesome combo

@LangChain Interrupt26 in NYC was amazing! 🗽
The energy of a sold out venue of agent builders from enterprises all over the world was so inspiring. @craigirwin and I spent the day demoing @CopilotKit and answering questions.
The favorite topic: how your app can have automatic learning built in 🤯

the biggest lesson that i took away from our jev webinar w/ @allietheicon is that jev actually enables REAL TIME inference
this is because jev is fast and cheap. you can:
- do content filtering on a stream in real time
- add guardrails that don't really impact ux
- monitor (and steer) agent trajectory w/o prohibitive cost
there's a lot more to say here but i find these examples in particular very compelling
curious what others are doing in real time w/ jev!

I built a starter app for @LangChain's new Managed Deep Agents product
Allows you to perform due diligence on @Shopify and get a cited research report
Langchain is moving fast - and the product is super easy to use.
Give it a try!

Parallel is now built into @LangChain managed agents.
And that’s a wrap on Interrupt NYC.
See you in London!
The talks may be over, but the Interrupt Reception sponsored by @tavilyai has just begun!
Try out LangSmith Fine-Tuning today with our dedicated CLI smithtune
A huge part of post training is finding and processing the right data. Our CLI handles pulling, selecting, processing trajectories from LangSmith, training on @FireworksAI_HQ and @baseten, then evaling with LangSmith.
Let me know what you think!

Final sessions of Interrupt NYC
🎙️ Fireside Chat w/ @RogoAI CEO & Co-Founder @gabestengel
🎙️ Evaluating Agentic AI at Scale with @linkedin
🔢 at @LangChain we've been putting a lot of thought into safe storage of user memories.
🔐 We wanted a secure way for a distributed agent to manage memory without it leaking outside of its intended context.
Here's a quick overview of the system and how to add user and agent memory to your managed deep agent - it's a single line of Python or TypeScript

A few things you can build:
1️⃣ Annotation queues: Review and label one (or many) runs at a time
2️⃣ Experiment comparisons: Compare outputs and metrics across experiments side by side
3️⃣ Trace reviews: Build trace or thread history views to inspect app behavior

Introducing LangSmith Custom Apps
Create any interface from your agent data with a prompt. If you can think it, LangSmith can build it.
Now GA.
Ok, this is insanely cool
@langchain is launching a model-tuning service w/@FireworksAI_HQ & @baseten
You can fine-tune your own custom model with the LangSmith Traces you already have - then compare & deploy! 👀

Proud to be a launch training partner for @LangChain's LangSmith Fine-Tuning and smithtune.
LangSmith traces → managed SFT on Fireworks → eval → deploy. One CLI, no training infra.
Get a Fireworks API key:
Then run smithtune:
