SoloTagger v0.20: Improved Caption Output Quality

solo Mar 12, 2026 Notes Original content from sololo.xyz. Please credit the source when reposting: https://sololo-au8.pages.dev/article/26-solotagger-v020-improved-caption-output-quality

  SoloTagger is an LLM-based image captioning tool.  
## What's Changed
1. The prompt passing mechanism has been optimized, significantly improving caption output quality.
2. The default temperature has been changed from 0.1 to 0, reducing model hallucinations.

## Note:
1. The prompt is the most important factor affecting caption output quality. Please refine and adjust it according to your specific needs.
2. In my own experience, with a well-crafted prompt, Qwen3.5-9B-UD-Q5KXL.gguf produces better output quality than llama-joycaption-beta-one-hf-llava.i1-Q6_K.gguf.
3. Among the Qwen3.5 series, models smaller than 9B produce noticeably lower output quality.
