Overview

Over dit model

DeepSeek V4.1 Flash Abliterated is a fast DeepSeek V4.1 Flash reasoning model with a 1M-token context window and tool-calling support, modified with abliteration to reduce refusal behavior; an optional thinking mode enables extended reasoning. Muapi exposes it through a single REST endpoint with async polling and Server-Sent Events streaming, so you can drop it into chat apps, agents and workflows without hosting GPUs. It is best suited to long-context reasoning, coding and tool-using agents. Pricing is pay-per-token at $0.66/M input tokens and $2.64/M output tokens, with no subscription. See also GLM 5.3 Flash Abliterated, DeepSeek R1 Llama 70B Abliterated, DeepSeek R1 Qwen 32B Abliterated. Browse the full lineup on the abliterated LLM API hub; related families: GLM Abliterated API and DeepSeek R1 Abliterated API. 'Abliterated' and 'derestricted' describe modifications that reduce the model's refusal behavior. They do not guarantee unrestricted output, and you remain responsible for complying with applicable laws and the Muapi terms of use.

How to Use DeepSeek V4.1 Flash Abliterated API

  1. Get an API key: Create a key in your Muapi dashboard.

  2. Send a prompt: POST prompt (plus optional system_prompt and max_tokens, up to 32768) to /api/v1/deepseek-v4-1-flash-abliterated. Set thinking to true for extended reasoning.

curl -X POST https://api.muapi.ai/api/v1/deepseek-v4-1-flash-abliterated \
  -H "x-api-key: $MUAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Explain how attention works in transformers.", "thinking": true}'
  1. Poll or stream: Poll GET /api/v1/predictions/{request_id}/result until status is completed, or stream tokens live from /api/v1/deepseek-v4-1-flash-abliterated/stream.
curl -X POST https://api.muapi.ai/api/v1/deepseek-v4-1-flash-abliterated/stream \
  -H "x-api-key: $MUAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Explain how attention works in transformers."}'
  1. Read the result: The generated text is returned in outputs. Usage is billed on actual token counts.

Common Questions

Frequently asked

What is DeepSeek V4.1 Flash Abliterated?

DeepSeek V4.1 Flash Abliterated is a fast DeepSeek V4.1 Flash reasoning model with a 1M-token context window and tool-calling support, modified with abliteration to reduce refusal behavior; an optional thinking mode enables extended reasoning.

What does abliterated mean?

Abliterated or derestricted models are modified to reduce refusal behavior. This lowers, but does not eliminate, refusals and does not guarantee unrestricted output.

How is DeepSeek V4.1 Flash Abliterated priced?

Billing is per token: $0.66/M input tokens and $2.64/M output tokens. A small minimum is reserved when the request starts and reconciled to actual usage.

Does DeepSeek V4.1 Flash Abliterated support streaming?

Yes. Stream tokens live from `/api/v1/deepseek-v4-1-flash-abliterated/stream` using Server-Sent Events, or poll the async endpoint.

How do I turn on thinking mode?

Send `"thinking": true` in the request body to use the reasoning variant. Leave it out for the standard, faster variant.

What is the context window?

The context window is about 1M tokens. Prompt and output together must fit inside it; `max_tokens` is capped at 32768. The endpoint accepts text input only.

Is output guaranteed to be unrestricted?

No. Abliterated models are less likely to refuse, but behavior varies by prompt and quality can differ from the base model. Evaluate it for your use case and follow applicable laws.
