Qwen3.8 27B Fast Xploded

The uncensored Qwen3.8 27B Fast API

MagmaRouter serves an uncensored build of Qwen3.8 27B Fast under the model id qwen3.8-27b-fast-xploded. It has 524k tokens of context, costs $1.50 per million input tokens and $5.00 per million output tokens, with cached input at $0.50, and supports tool calling, so it can drive an agent. One key works on the OpenAI-compatible endpoint (https://api.magmarouter.com/v1) and on the Anthropic-compatible one Claude Code uses, so the same Qwen3.8 27B Fast model plugs into Claude Code, Cline, opencode, SillyTavern, the OpenAI SDK and anything else that takes a custom base URL.

Prices are per million tokens. Intelligence is the Artificial Analysis Intelligence Index of the base model.

What the uncensored tag actually means

qwen3.8-27b-fast-xploded is tagged uncensored, which here means a loosely aligned finetune. It refuses far less than a frontier instruct model, but it is not abliterated: the refusal behaviour was reduced by training, not surgically removed, so it can still decline. Nothing about the tag promises it will answer anything.
