DeepSeek V4 Flash Local Deployment Hits 16k Output Limit
El_90 · reddit · 2026-08-05
A developer encountered an output length limitation while locally deploying the DeepSeek-V4-Flash-0731 model. When running inference using llama-server, the model's output is forcibly cut off at 16k tokens, reporting a maximum output limit reached, even when the context size is configured to 128k.
The author notes this isn't due to an infinite loop, but naturally occurs during complex tasks like asking the model to plan and implement an entire project based on a PRD. They suspect this might be a hard constraint specific to this model and are seeking community confirmation.
