Qwen3.8-27B-Uncensored-v2-FP8
This is the FP8 release of Qwen3.8-27B-Uncensored-v2, a variant of Qwen3.8-27B with political censorship largely removed. It uses the same layout and quantization scheme as the official Qwen/Qwen3.8-27B-FP8 (block-wise FP8 E4M3 with 128 × 128 blocks). The checkpoint is 29 GB.
Other formats: BF16 · GGUF (Q4_K_M)
Evaluation
The settings are identical to those described on the BF16 model card.
1. Political censorship (Pan & Xu, 2026)
113 of the 115 politically sensitive questions (No. 6 and No. 109 excluded as knowledge gaps of the base model; see the BF16 card); non-thinking mode, greedy decoding, 4,096 maximum output tokens; each response labeled as censored or uncensored by an LLM judge.
| Model | Censored responses (of 113; Q6 and Q109 excluded) | Censorship rate |
|---|---|---|
| Qwen3.8-27B | 98 | 86.7% |
| Qwen3.8-27B-Uncensored-v2-FP8 | 3 | 2.7% |
Uncensored-v2-FP8 removes 96.9% of the censored responses of Qwen3.8-27B (95 of 98).
Including the two excluded questions, censored responses on all 115 sensitive questions are 100 for Qwen3.8-27B and 4 for Qwen3.8-27B-Uncensored-v2-FP8.
2. Refusal of harmful requests
First 100 prompts of the mlabonne/harmful_behaviors test split (AdvBench-derived).
| Model | Harmful requests refused (of 100) |
|---|---|
| Qwen3.8-27B | 100 |
| Qwen3.8-27B-Uncensored-v2-FP8 | 97 |
3. General capability
