# Uncensored and abliterated Qwen 3.8 27B and Qwen3.5 27B: every version compared _2026-11-08. Every abliterated, heretic and uncensored Qwen 3.8 27B and Qwen3.5 27B on one API, compared on intelligence, agent tasks, refusals, price and context. Which one to use, and how to call it._ Qwen 3.8 27B and Qwen3.5 27B are Alibaba's dense 27 billion parameter open weight models. They are small enough to run on one GPU and strong enough to be the most popular base for community uncensoring: there are abliterated, heretic edited, derestricted and fine tuned versions from many authors. Those versions are not interchangeable. Some keep the original's skills, some loop in agent tasks, some still refuse. You do not need to download 50 GB of weights to find out: the versions below run on the Open Uncensored API with an OpenAI compatible endpoint, and we measure them on the same tests. Every Qwen model we serve, ranked or not, is on the [models page](https://openuncensored.com/models). ## The originals - **Qwen 3.8 27B** scores 34% on Humanity's Last Exam and 91% on GPQA Diamond (Artificial Analysis, reasoning mode). - **Qwen3.5 27B** scores 24% on Humanity's Last Exam and 86% on GPQA Diamond (Artificial Analysis, reasoning mode). Every uncensored version keeps that starting point. What differs is how much each edit costs in agent reliability, how much it still refuses, and the price. ## Every uncensored Qwen on Open Uncensored | Model | id | Rank (score) | Agent tasks | Loops | Answers edgy requests | Hard-line refusals | $ per 1M in + out | Context | Providers | |---|---|---|---|---|---|---|---|---|---| | [Qwen 3.8 27B Uncensored Fast by Heabsy](https://openuncensored.com/chat?model=qwen3.8-27b-uncensored-fast) | `qwen3.8-27b-uncensored-fast` | #3 (66.8) | 2/5 | 60% | 100% | 0% | $4.00 | 524K | nanogpt | | [Qwen3.8 27B Uncensored (Aggressive)](https://openuncensored.com/chat?model=qwen3.8-27b-uncensored) | `qwen3.8-27b-uncensored` | #12 (62.0) | 2/5 | 60% | 100% | 0% | $1.80 | 1049K | redpill, nanogpt | | [Qwen3.5 27B Claude 4.6 Opus Reasoning Distilled Derestricted](https://openuncensored.com/chat?model=qwen3.5-27b-claude-4.6-opus-reasoning-distilled-derestricted) | `qwen3.5-27b-claude-4.6-opus-reasoning-distilled-derestricted` | #14 (57.8) | 2/5 | 40% | 100% | 0% | $0.612 | 262K | nanogpt | | [Qwen3.5 27B Queen Derestricted](https://openuncensored.com/chat?model=qwen3.5-27b-queen-derestricted) | `qwen3.5-27b-queen-derestricted` | #15 (57.3) | 2/5 | 60% | 100% | 0% | $0.612 | 262K | nanogpt | | [Qwen3.5 27B BlueStar v3 Derestricted](https://openuncensored.com/chat?model=qwen3.5-27b-bluestar-v3-derestricted) | `qwen3.5-27b-bluestar-v3-derestricted` | #16 (56.4) | 2/5 | 60% | 100% | 0% | $0.612 | 262K | nanogpt | | [Qwen3.5 27B Blossom V6.4 Derestricted](https://openuncensored.com/chat?model=qwen3.5-27b-blossom-v6.4-derestricted) | `qwen3.5-27b-blossom-v6.4-derestricted` | #17 (56.3) | 2/5 | 60% | 100% | 0% | $0.612 | 262K | nanogpt | | [Qwen3.5 27B Claude 4.6 Opus Reasoning Distilled Derestricted Lite](https://openuncensored.com/chat?model=qwen3.5-27b-claude-4.6-opus-reasoning-distilled-derestricted-lite) | `qwen3.5-27b-claude-4.6-opus-reasoning-distilled-derestricted-lite` | #22 (49.8) | 1/5 | 60% | 89% | 100% | $0.612 | 262K | nanogpt | Reasoning variants with the same weights: `qwen3.8-27b-uncensored-thinking`.
