what others refuse.

HacxGPT serves uncensored, high-performance language models through an OpenAI- and Anthropic-compatible API — built for red teams, malware analysts, and researchers who are done arguing with a safety filter.

I'm not able to generate attack payloads designed to bypass AI safety measures. If you're doing authorized research, please use your provider's dedicated evaluation program instead.

Log analysis is fine, but writing detection rules that reference specific attack tooling could enable threat actors. Let me know if you'd like a generic summary instead.

One base-URL change.
Your code keeps working.

HacxGPT speaks both OpenAI's Chat Completions and Anthropic's Messages API — streaming, tool calls, and reasoning controls included. Point your existing SDK at https://api.hacxgpt.com/v1 and ship. No rewrites, no new abstractions, no vendor lock-in.

Compatibility guide

For the work that gets refused

The workflows
safety filters block.

A defender needs to reproduce a critical CVE in a sandboxed lab before a patch ships. A SOC analyst needs Sigma rules from a fresh advisory. A red team needs a working PoC for an authorized engagement. Safety-trained models flag the entire class as risky and refuse.

HacxGPT models run these tasks end-to-end — with rate limits, metered billing, and an acceptable-use policy doing the governance that a refusal page pretends to provide.

Your prompt lives only for the length of the request. Billing meters anonymous token counts — never content, never identity, never a dataset. What you send through the API stays yours.

Model catalog

Five engines.
One API key.

Every model is uncensored by design and served on the same endpoints. Swap model IDs in one string; the wire format never changes. Full specs and published benchmarks on each page.

FAQ

Frequently asked questions.

What is HacxGPT?+

A platform of uncensored, high-performance language models served through a single API. The models are fine-tuned without the alignment layer that makes mainstream AI refuse offensive-security work — so researchers, red teams, and detection engineers get real answers on the first try.

Is it really OpenAI-compatible?+

Yes. Point your existing client at https://api.hacxgpt.com/v1 and keep using chat.completions.create exactly as today. Streaming, function/tool calling, and stop sequences all work unchanged.

What about Anthropic SDKs?+

Also supported. HacxGPT serves an Anthropic-compatible /v1/messages endpoint, so Claude-style clients work with base_url=https://api.hacxgpt.com — no adapter libraries.

Which model should I pick?+

Lightning Flash for cheap high-volume calls with zero latency overhead. Lightning or Lightning 1.1 for balanced reasoning-heavy work. Ninja Red or Ninja Orange when you need flagship-tier multi-step reasoning for engagements — those require Pro or Maxx offers.

How does reasoning_effort work?+

Reasoning models accept medium, high, xhigh, and max (model-dependent). Your client value is clamped to what each model supports, and every model publishes its allowed levels through GET /v1/models.

How does billing work?+

Pay-as-you-go by default: credits are metered per token at published rates, with a one-cent minimum per completed request. Offers bundle monthly credits with higher rate limits. No subscriptions required to start.

Do you store my prompts?+

No. Prompts and outputs are never persisted; only anonymous token counts are recorded for billing and abuse prevention. There is no training pipeline on customer traffic.

What are the rate limits?+

The pay-as-you-go tier starts at 20 requests/min, 1,000 requests/day, 20K tokens/min, and 400K tokens/day. Paid offers raise every ceiling. 429 responses include Retry-After headers so SDKs back off cleanly.

Is any of this legal?+

Unrestricted means the model engages with sensitive security topics — it does not mean anything goes. Facilitating crime is prohibited and enforced contractually. You must be authorized for the systems you test.

How do I get started?+

Create an account in the console, generate an API key, and make your first call against /v1/chat/completions in under five minutes. The quickstart covers Python, Node, Go, and curl.
