DeepSeek V4 Flash Free: output truncated mid-sentence without warning

Issue

DeepSeek V4 Flash Free model frequently stops output mid-sentence without any error or warning message. This makes normal conversation nearly impossible.

Symptoms

• Output cuts off after 1-2 lines
• Stops mid-sentence
• No error code or warning returned
• Requires repeated retries to complete a response
• Happens consistently across different prompts

Steps to Reproduce

1. Use DeepSeek V4 Flash Free model
2. Enter any prompt
3. Output stops abruptly after ~1-2 lines without completion signal

Environment

• OS: Windows 11
• Terminal: PowerShell 7
• OpenCode: latest version

Suggestion

Consider adding client-side auto-retry or a friendly warning when output is truncated, so users know the response was incomplete.
