I've been having a similar issue when using Cursor. Model makes a bunch of tool calls and then stays silent.

I've been having a similar issue when using Cursor. Model makes a bunch of tool calls and then stays silent.

Same here with Cursor in the middle of the thread. Due to T3Code not having export session functionality, I had to start a new Codex thread asking where T3Code saves sessions to get back my plan. I have stopped using T3Code for now because of this issue.

[pozgo]

Same... I can see requests going to Anthrpic as I'm using meridian proxy for my opencode so seems the issue is only on T3 Code side

[KhalidWar]

Same issue here. No responses even though the agent is doing the work in the background. It reviewed the PR I asked it to and left a comment but none of that showed on the UI. This only affects DeepSeek models not Claude Opus.

• T3 Code v0.0.23 (Electron desktop, macOS Tahoe)
• Backend: opencode (port 3773)
• Model: DeepSeek V4 Pro
• Same symptom: user messages render, assistant messages don't
