Key points
- Three Jinja templates added to Qwen3.8-Flash-Next, including a Sharp‑naze‑chattemplatev1.4.jinja with a terseness block from Sharp v22.5.0.
- Terseness is on by default; disable with chattemplatekwargs or --chat-template-kwargs '
- {'terse': False}
The author notes that the templates were tested against 158 assertions in jinja2 and 16/16 cases in llama.cpp, with no changes to the base prompt. The Sharp variant improved edit‑format compliance from 77% to 46% on a fine‑tuned Qwen model. The post also lists fixes that address developer role merging, reasoning effort mapping, and clearer tool‑call errors. The base template is credited to Unsloth, with additional ideas from froggeric and peculiar‑ragdoll.
