Cloudflare/clef-flash: what it needs to run
Cloudflare/clef-flash is a fine-tune of Qwen/Qwen3.5-9B. Its configuration matches Qwen3.5-9B's on every field that decides memory, so Qwen3.5-9B's requirements are this repository's.

Geometrypublished data. Both configurations are published files, read at the revisions named below and compared field by field. Not a test that the model loads.Qwen3.5-9B (Qwen/Qwen3.5-9B) — every compared field is stated by both and equal.
Before you use those figures
- Its safetensors index counts 9,409,813,744 parameters against the base's 9,653,104,368 (2.5% apart). The compared geometry is the same, so the difference is in weights this comparison does not cover, and the base's file sizes are off by about that share for this repository.
