MiniCPM-o 4.5 — Sculpt Aggressive (keep_frac=0.7)

30% compression — maximum compression

Structurally pruned from openbmb/MiniCPM-o-4_5 using Dystrio Sculpt. Only the Qwen3-8B LLM backbone is pruned — vision (SigLip2), audio (Whisper), and TTS (CosyVoice2) modules are untouched.

Compression Details

• keep_frac: 0.7 (30% of MLP intermediate neurons removed)
• Method: Structural pruning with live teacher distillation (alpha=0.5)
• Repair: Full repair pass with workload-matched training data
• Architecture: All multimodal modules preserved; only LLM MLP layers compressed

Intended Use

Drop-in replacement for MiniCPM-o 4.5 with reduced memory footprint. Suitable for:

• LoRA fine-tuning on memory-constrained GPUs
• File description and indexing workloads
• Multimodal inference with lower VRAM requirements
