The Gemma Abliterated API gives you programmatic access to Gemma 4 26B A4B Abliterated, Gemma 4 31B Gembrain Abliterated and Gemma 4 31B SDFT Abliterated through one Muapi API key. Every endpoint takes the same request body: prompt, optional system_prompt, max_tokens, and image_url on vision-capable models.Abliterated models are language models modified to reduce their built-in refusal behavior. Abliteration and related techniques (obliteration, derestriction) lower how often a model declines a request; they do not guarantee unrestricted output, remove every limit, or change Muapi's acceptable-use policy. You remain responsible for how you use the output.

This page covers Gemma 4 26B A4B Abliterated, Gemma 4 31B Gembrain Abliterated and Gemma 4 31B SDFT Abliterated on Muapi. Gemma 4 26B A4B with refusal behavior reduced through abliteration: an efficient mixture-of-experts chat model with a 65K-token context window, text in and text out. Gemma 4 31B Gembrain with refusal behavior reduced: image input, a 262K-token context window, and a flat token rate for general and creative chat.

Submit a prompt, optionally with a system_prompt to set persona and tone and an image_url on vision-capable models, and poll for the generated text. Typical uses include creative writing, red-team and safety research, evaluation against the unmodified base model, and applications where a base model's refusals get in the way of legitimate work. Abliterated models are language models modified to reduce their built-in refusal behavior. Abliteration and related techniques (obliteration, derestriction) lower how often a model declines a request; they do not guarantee unrestricted output, remove every limit, or change Muapi's acceptable-use policy. You remain responsible for how you use the output.
Every endpoint accepts the same request body and returns text through the shared result endpoint, so switching models is a one-line change.
Abliteration and related techniques lower how often the model declines a request. Behavior varies by model and prompt, and is not a guarantee.
Set a system_prompt to steer persona, tone, and output format for creative, analytical, or evaluation work.
Billing follows the token counts each call returns. There is no subscription and no model hosting to manage.
Pass an image_url to Gemma 4 31B Gembrain Abliterated, Gemma 4 31B SDFT Abliterated.
Reduced refusals do not mean no rules. Muapi's acceptable-use policy and applicable law still apply to what you generate.

An abliterated language model is a model whose refusal behavior has been reduced by editing the internal direction that drives refusals, usually without retraining from scratch. Related terms such as obliterated and derestricted describe similar techniques. The result tends to decline fewer requests than the original model, but it is not a guarantee and quality can differ from the base model.
Gemma 4 26B A4B Abliterated, Gemma 4 31B Gembrain Abliterated and Gemma 4 31B SDFT Abliterated. Each is a separate endpoint with its own model name in the URL.
Billing is per token, deducted after each call from the counts the model returns. Rates start at $0.30 per million input tokens; see the pricing table for every model.
No. Reduced refusals do not mean unrestricted output, and each model's knowledge and quality still bound the answer. You are responsible for how you use the output, and requests that violate Muapi's acceptable-use policy or the law are not permitted.
Yes on Gemma 4 31B Gembrain Abliterated, Gemma 4 31B SDFT Abliterated: add an image_url next to your prompt. The others are text-only.
POST to /api/v1/<model-name> returns a request_id. Poll /api/v1/predictions/{request_id}/result until the status is completed, then read the text from outputs.
Yes. All 3 models here support tool calling: Gemma 4 26B A4B Abliterated, Gemma 4 31B Gembrain Abliterated and Gemma 4 31B SDFT Abliterated. In Claude Code, set ANTHROPIC_BASE_URL to https://api.muapi.ai/anthropic and ANTHROPIC_AUTH_TOKEN to your Muapi API key, then start it with claude --model gemma-4-26b-a4b-abliterated (also set ANTHROPIC_DEFAULT_HAIKU_MODEL and ANTHROPIC_SMALL_FAST_MODEL to the same id). Codex CLI works too: add a model provider with base_url https://api.muapi.ai/openai/v1 and set model to the same id. Quality varies by model and smaller models can skip steps on multi-file tasks, there is no prompt caching so every turn is billed for the whole conversation so far, and each response is capped at 16,384 tokens.
