clef-bf16 (bf16)

Full-precision (bf16) PyTorch port of Cloudflare/clef, for vLLM / TGI / Xinference / transformers users who don't want the GGUF quant.

• Format: pytorch_model.bin (bf16). safetensors conversion in progress.
• Architecture: identical to the original — drop-in for AutoModelForCausalLM.from_pretrained("rty813/clef-bf16").
• Also loads in vLLM (vllm serve rty813/clef-bf16) and Xinference (search "clef").

Clef

• Announcement: Clef decision models on the Cloudflare blog
• Decision Index leaderboard: clef-evals.workers-ai-mle.workers.dev

Clef is a 27B multimodal model that turns a state and a schema of typed questions into decisions. It reads the state as text, JSON, images, or video, and returns a probability for every allowed option of every question in a single forward pass. There is no free-form text generation and no output parsing.

The Clef API is fully compatible with Jev and SystemOne.

Clef is post-trained from Qwen/Qwen3.8-27B. See Clef-Flash for the smaller, faster variant.

Model

• Backbone: Qwen/Qwen3.8-27B with its vision encoder, stored as standard sharded safetensors.
• Joint schema head: a small transformer head that reads the backbone's final hidden states, routes evidence from the state to each question, and scores all options of all questions jointly.
• Output: one logit per allowed option for each question. Apply a softmax per
