Today I got the best feedback from a user. “Would prefer to have my workout ready instead of needing to talk to AI every time” also “Would love that remembers exactly what workout did I do. Even with context loops for the agent the non deterministic part always changes the results a bit. But letting AI build a workout every time, it’s very token intensive, but I know exactly what to do to avoid this.

@hrprtsingh9 The approval is quick just 2 clicks, check the proposal, then approve and it’s ready. But proposing does take a while since the agent have to run a series of tools for context. I’m still trying to find the right balance and handle the non-deterministic part.

@natan_RIAL Human-in-the-loop for workout plans is smart. Nobody trusts AI with their body yet. How fast is the approval flow — does it feel like friction or safety?

Here is an example of a human-in-the-loop agent I built for my app. The agent would run tools to get user context, and then propose a workout. User needs to approve or requests edits. The workout proposal is part of my state, which follows the workout model type so I can reuse in UI. If approve, I run a tool to write in DB and create workout for the user. Since the proposal is part of state, the agent can iterate on it as long as the graph loop is open.

@sydneyrunkle @hwchase17 Great post. When would you recommend middleware over just building directly in LangGraph? For those of us already comfortable with graphs, what's a good reason to switch?

new series this week -- how to use middleware to customize your agent harness! case 1: business logic and compliance some compliance logic needs to live outside of the prompt. for example, use langchain's builtin PIIMiddleware to mask/redact/hash/block PII.

Just made my app freemium to see how it goes. A lot of people liked the features but not everybody was willing to add their credit card right away mostly in Latin America. Of course the AI coaching feature is still paid but I made common GPS, lift tracking, Apple Watch integration free up to a certain point. I got 3 trials last night so will see.

What makes someone a founder? I really struggle to call myself a founder until my app is better positioned. Like anybody can be a founder tomorrow if they deploy a website, add a stripe button, and post about it.

How many people is using @LangChain langsmith to Eval their agents? It’s pretty good UI. I used the @OpenAIDevs openAI API rn, and I just noticed a couple improvements thanks to this.

I love building agents, apps, websites, play with the terminal. But, I feel like I have to read sometimes so I stay well rounded. Reading “The Changing World Order” by Ray Dalio right now

What do you think of this langgraph agent. I made a carrousel generator for personal brands at the link below. Really curious if people want image generation or App Store marketing images. pixel-carrousel-frontend.vercel.app
