Thanks for the Prompt Enhancing models
- What is the difference of these two PE models? Special fine-tuning for t2i,i2i? Could we use one of it, to do PE(in different llm workflow with different system prompt)?
- Could we just use qwen3vl_8b_int8_convrot.safetensors to do PE(in different llm workflow with different system prompt)?
From the original repo:
Both checkpoints are fine-tuned Qwen3.5-VL 9B, not the official base model:
stock architecture (model_type: qwen3_5,Qwen3_5ForConditionalGeneration,
hybrid linear/full attention, thinking on by default), post-trained weights.
Theirchat_template.jinjaandtokenizer.jsonare byte-identical, which is
what makes one codebase honest rather than merely convenient.Each task has its own checkpoint and its own system prompt. They are not
interchangeable and there is no merged prompt: the answer contract is part of
what each model was trained on. Point--ckptat one and give it that model's
prompt (via--system-prompt, or ship it assystem_prompt.txtinside the
checkpoint directory and it is picked up automatically).Pointing
--ckptat the official open-source Qwen3.5-VL 9B release will load and
generate, but it was never trained against either system prompt, so it does not
reliably emit the answer JSON -- expectparse_ok: falseon most rows.
So technically you can do it but your milage may vary
Thank you @Novmik . Based on your info I do further search.
Yes. It just like Chatgpt image 2.x , the background system fine-tuning the prompt heavily, to make a simple idea to a masterpiece.
In local, to make the same effects, same quality, QI2.1 rely heavily on PE too.
