Hey, I accepted an update this morning, and since then, the message i wrote prior to that will not be sent no matter what i do. Nothing happens after hitting Chat or Chat with codebase.
I have a long thread using this chat. It’s stuck only while using this one, which was open when i accepted the upgrade. composer and new chats work fine.
I tried starting a new chat window, and it works, but it doesnt hold any memory from my main progress. Seems like the project will be set back a lot if i give up on this chat window.
Exactly, I am having the same problem with recently. It wouldn’t respond in a chat after reopening the app. It forcing me to open new chats with absolutely no memory of was being built so far every time. It has become very annoying and sets back development time a lot. They have to fix this issue soon.
You can copy your previous chat conversation, save it to a file, and attach it to the context. It’s not very convenient, but it might work as a temporary solution.
Main models like GPT-4 or Claude 3.5 Sonnet are limited by their context windows. Conversations can’t go on indefinitely—they have fixed token limits. Every part of the conversation—code snippets, instructions, past messages—takes up space in this context. When the window overflows, the model “forgets” the earliest parts of the dialogue. This isn’t a Cursor problem; it’s a limitation of all AI. That’s just how they work, unless you’re using a model with a long context window.
Here’s an interesting post on how to work with large projects:
But recently when I use Claude’s latest model, the output is very laggy, while the GPT-4 model isn’t. This must be a Cursor issue. When I use Claude on the official website or use third-party applications to call Claude’s latest model API, the output isn’t laggy.
