Empero Releases Qwythos-27B-v1: Open-Weights Reasoning Model Based on Qwen3.5

LinkkodeeAnnouncement

Empero has released Qwythos-27B-v1, an open-weights bf16 reasoning model published under the Apache-2.0 licence. Sized up from Qwythos-9B on a Qwen3.5-27B base, it preserves native function calling, multimodal vision, MTP, and a 1M context window.

Key points

  1. Built on Qwen3.5-27B with dense hybrid attention (Gated-DeltaNet and periodic full attention), licensed under Apache-2.0.
  2. Preserves full base capabilities without ablation: native MTP for self-speculative decoding, full vision support, and 1M context via YaRN.
  3. Native function calling works via standard tool schemas without requiring wrappers.
  4. Custom GGUF quants keep Gated-DeltaNet state tensors at Q8_0 or higher to prevent quality degradation in K-quants.
  5. Intentionally uncensored to handle cybersecurity, biomedical, and deep technical queries without refusal.
  6. Release checkpoint v1 reflects pre-reinforcement-learning state; an RL-tuned v2 is planned.

Why it matters

Fine-tuned models at the 27B scale frequently drop features like multimodal vision or multi-token prediction during adaptation. Qwythos-27B retains the entire architecture intact and fits comfortably onto consumer 24GB GPUs using the Q4_K_M quantization.

Analysis

Empero takes a transparent release approach, prioritising measured target-format acquisition and local execution over broad, unvalidated benchmark claims. Retaining Q8_0 precision for the sensitive SSM state path within lower K-quants ensures structural integrity for linear attention at a minimal size trade-off. The unaligned, uncensored nature makes it capable for research and code execution, though production deployments will require external guardrails.
