MiniCPM-V-4.7-1B-DSpark GGUF

Q8_0 GGUF conversion of openbmb/MiniCPM-V-4.7-1B-DSpark for use with Magnitude.

This is a speculative drafter for openbmb/MiniCPM-V-4.7-1B and its tokenizer. It requires the corresponding target model and a runtime with DSpark support; it is not a standalone language model. The draft has five layers and proposes 15 tokens per forward pass.

• Conversion: F16 intermediate, then Q8_0, using llama.cpp revision 43fe9c64281ef735046adc025e9e7559a1f659a5 with the workshop's explicit drafter metadata handling.

Draft metadata

• dflash.attention.causal = false: the draft block uses bidirectional attention.
• dflash.sample_from_anchor = true: proposal selection starts at the anchor row.
• Causality is supplied explicitly for conversion from the DSpark reference implementation; the upstream checkpoint configuration omits it. Tokenizer dispatch uses the target's Qwen3.5 text tower.
• Tensor mappings and draft hidden states, Markov logits, confidence, and proposal selection were checked against reference code with shared synthetic target inputs. These are conversion checks, not end-to-end generation or performance measurements.
