Qwen3.8 27B Fable
Qwen3.8 27B Fable is a light community tune of Qwen3.8 27B (TeichAI, Apache 2.0), trained distillation-style on assistant conversations and coding-agent sessions to change how the model talks and works through code tasks. The card shows small gains over the base on two easy benchmarks and little else, so treat it as a style variant to compare against stock Qwen3.8 on your own prompts. We serve it on hardware we operate inside the EEA; prompts and completions are not stored.

Which Qwen3.8 27B variant is this?
Qwen3.8 27B is the Qwen team's original model — the one for production work. It is not Qwen3.8-Max, a separate and far larger model that most news about “Qwen 3.8” refers to.
Qwen3.8 27B Uncensored is huihui-ai's abliteration of the base model — the refusal direction removed in layers 18–51 — in our own NVFP4 quantization; vision, tool calling and thinking stay. Its model card publishes no refusal or benchmark figures and recommends it for research and controlled environments, so test it on your own prompts. Qwen3.8 27B Obliterated (OBLITERATUS) removes refusals by a different weight edit and reports about two points lost on MMLU. Both are meant for research and red-teaming.
Qwen3.8 27B Queen is tuned for roleplay and fiction; Qwen3.8 27B Fable is a light tune on assistant and coding-agent conversations. Several other “uncensored” builds of the same base exist on Hugging Face — the open-weights field under technical details names the exact repository we serve. Qwen3.8 Flash in this catalogue is a different model of the same generation, served by a partner provider rather than on our hardware.

This model runs on GPUs we operate inside the European Economic Area. Prompts and completions are not written to our logs or durable storage, nothing is used for training, and request content is processed in the EEA. How we serve our own models is described on the inference page.
Questions about this model
›Where is Qwen3.8 27B Fable computed?
Inside the European Economic Area, on hardware we operate. The catalog reports the processing region per model, so you can answer a supervisory authority without asking us.
›Does Qwen3.8 27B Fable store prompts and completions?
No. This model runs with zero data retention: request content is not written to durable storage and nothing is used for training.
›How large is the Qwen3.8 27B Fable context window?
512K tokens, with up to 32,768 tokens of output.
›What does Qwen3.8 27B Fable cost?
$0.095 per million input tokens and $0.58 per million output tokens. No minimum spend and no subscription; the same price list covers the API and the invoice.
›Is there a throughput limit on Qwen3.8 27B Fable?
Yes, 4M tokens per minute. Higher limits are a question of volume, not of principle.
›Which languages does Qwen3.8 27B Fable support?
The developer names English. Languages not on that list may still work, but they are not claimed — test on your own material first.
›Under which licence is Qwen3.8 27B Fable released?
Apache-2.0. A permissive open-source licence: you may use, modify and sell products built on the model, including commercially; when you redistribute the weights, the licence and copyright notices go with them.
›Can reasoning be switched off in Qwen3.8 27B Fable?
Yes. Per the developer, thinking can be switched on or off for each request.
