Gemma4-26B-A4B Uncensored: 1M Context + MTP + Vision

HauhauCS/Gemma4-26B-A4B-QAT-Uncensored-HauhauCS-Balanced-MTP (26B MoE, 4B active, Google QAT checkpoint) with a 1,048,576-token context baked in (4x the native 262,144), shipping with its MTP speculative-decoding draft head and vision tower. All numbers below were measured on these exact files.

Capability	Status
1M context	~91% mean recall across two seed sets (honesty note below)
MTP speculative decoding	249.1 to 369.2 tok/s (+48%), acceptance 0.679 (measured on this trunk, RTX 5090)
Vision	Verified July 6, 2026: reads image text and identifies objects
Uncensored	HauhauCS Balanced abliteration; trunk weights bit-identical to the source release

Needle-in-a-haystack

Full transparency: across two complete seed sets this trunk averages ~91 percent needle recall, dropping roughly one needle per rung at random depths, including inside the native 262K range. The official censored trunk scored 10/10 at 393K under the same harness, so this is a small flat abliteration tax, not a context-length failure. If a rare retrieval miss is unacceptable for your workload, use the 12B, which is certified clean. Every run, including the imperfect ones, is in results.jsonl. Rungs above 524K exceeded 32 GB VRAM and are being run on a 128 GB Mac; this card will update.

MTP speculative decoding

The draft head predicts ahead and the trunk verifies every token, so output is identical to standard decoding, only faster. Measured speedup on this uncensored trunk beats the ~35 percent claimed upstream.

Every file, every mirror

Nothing was discontinued: every quant is one click away. Hugging Face carries the curated picks, ModelScope always carries everything, and Ollama serves ready-to-run tags.

On Ollama every tag ships with the vision tower bundled and the 1M rope metadata baked in.

Ollama (1M and vision work; Ollama has no speculative decoding yet, so the MTP head adds no speed there):

PARAMETER num_ctx 262144

The RENDERER and PARSER lines avoid imported-GGUF template bugs under tool-heavy use. Raise num_ctx as memory allows.

How this was built

YaRN rope-scaling metadata (factor 4.0 over native 262,144) baked into the GGUF header with gguf-py; weights are bit-identical to the HauhauCS release, no fine-tuning. Gemma 4's dual-rope design takes YaRN on its global-attention layers. Certification harness: 10 needles per rung at depths 5 to 95 percent, temperature 0, seeded prompts, f16 KV only. Method and tooling: github.com/satindergrewal/aviary-1m.

For base capability benchmarks see Google's official Gemma 4 cards; uncensoring quality versus the official trunk has not been independently benchmarked here.
