Build a MemGPT Discord Agent in LangGraph Cloud

In this tutorial, we create a MemGPT-inspired Discord agent using LangGraph Cloud, enabling chatbots to remember user interactions across conversations for a more personalized experience.
Key components of the MemGPT agent:
1. Core memories: Persistent user information
2. Recall (semantic memories): Context-based retrieval
3. Management via tool use
We'll cover:
- Implementing the agent graph
- Deploying the agent on LangGraph Cloud
- Creating the Discord bot
- Writing tests and evaluations for the agent
By the end of this tutorial, you'll understand how to build, deploy, and evaluate a Discord bot with long-term memory capabilities.

This is epic! Glad to see you put memgpt together. Fingers crossed to get access to langgraph cloud soon 💜

[@arush7169]

Awesome walkthrough! It\'d be fantastic to see some advanced TypeScript examples. I\'m interested in creating a robust help desk solution.

[@Ankitamahato-ze5ix]

Great video! I\'d love to see more TypeScript content. Could you do an advanced tutorial on integrating LangChain into a support ticketing system?

[@IdPreferNot1]

Want to commit to LangGraph for agents but no LangGraph Cloud access :(

[@kapilsonawane2208]

Thanks for the great content! More TypeScript tutorials would be super useful, especially if you cover complex applications like support ticket management systems.

[@Vimlesh-qf8fw]

Loving these LangChain videos! Can you include some advanced TypeScript tutorials? Specifically, something on developing a custom support platform would be great.

[@lala-kq5ho]

MemGPT is amazing

[@AdityaKumar-zt4rz]

This was really helpful, thanks! Any chance you could cover more TypeScript, especially how to build a sophisticated customer service system?

[@robboerman9378]

Oof, this is so cool. So many ideas triggered ❤ if only I could use LanGraph Cloud 😢

[@ikurious]

Unlisted?

[@93simongh]

I wish you'd also show how to build these in a self hosted, local environment.

[@themax2go]

won't do it cuz it'd take away their revenue

[@datawarrior2023]

This is great, but showing us things we can't do since not all of us are privileged enough to have access to LangGraph Cloud without even mentioning it isn't available, is not cool.
