MedusaGemma-E4B-MLX-4Bit

Tagline: One spine. Many heads.

Started as a MacBook Pro experiment and grew into a full composite release.

Model Summary

MedusaGemma-E4B-MLX-4Bit is the compact Apple Silicon build of MedusaGemma-E4B: a fused local model for offline inference, reasoning, and practical work.

Parameter note: E4B-family model: approximately 4.5B effective parameters / ~8B including embeddings; the MLX 4-bit export stores fewer values because of quantization.

What Went Into It

This is the 4-bit MLX release for Apple Silicon local use. The donor lineage and adaptation work are baked in so this repo is a single downloadable model artifact.

Primary lineage:

google/gemma-4-E4B-it
DavidAU/gemma-4-E4B-it-The-DECKARD-HERETIC-UNCENSORED-Thinking
DavidAU/gemma-4-E4B-it-The-DECKARD-V2-Strong-HERETIC-UNCENSORED-Thinking
Jiunsong/supergemma4-e4b-abliterated

Stamsam custom dojo / training

The adaptation stack was built on:

pocket-polymath-seam-adapter
pocket-polymath-legacy-adapter
pocket-polymath-legacy-4096-adapter
pocket-polymath-broad-growth-adapter
pocket-polymath-ultimate-dojo-adapter

Synthetic dojo data came from glm-5.1:cloud via Ollama, plus Gemini-generated material from the same workflow.

Quantization Notes

Format: MLX
Quantization: 4-bit
Target hardware: Apple Silicon

Best For

fast Apple Silicon local inference
offline assistant work
structured reasoning and business analysis
general writing and summarization
practical code generation
integration with the Pocket Polymath stack

Keep In Mind

The bare MLX build can still make arithmetic mistakes without the stack.
The bare MLX build can still miss exact refusal behavior without the stack.
The bare MLX build can still miss strict formatting constraints without validators.

Evaluation Snapshot

Fresh full holdout: 40/40
External-lite cleaned: 256/265, 96.6%
MBPP repair mode: 20/20 final on the cleaned slice and fresh holdout
Reasoning leaks: 0
Bad claims: 0

Safety and Reliability

The Pocket Polymath stack adds:

reasoning leak guard
missing-data refusal router
arithmetic router
structured-output validators
completion checks
optional sandboxed code verifier/repair mode
