DeepSeek V4.1 Flash Abliterated

by Morph

DeepSeek V4.1 Flash Abliterated is Morph's version of DeepSeek's V4.1 Flash with its refusal behaviour removed, so it follows through on the vulnerability research, red-team and moderation-data requests that the original declines. Morph serves it on a dedicated deployment and enables it per organization. It keeps the base model's shape: text and image input, a context window of about one million tokens, tool calling and strict structured output. It reasons before answering by default, and a reasoning_effort parameter from none to max sets the thinking budget, with none switching reasoning off. It suits red-team prompt generation, abuse and moderation dataset creation, security tooling and agent evaluations where a refusal would end the task, at a Flash-tier price.
