Introducing Onyx Legion: Many Minds, One Answer

Today we're launching Onyx Legion, the first multi-AI deliberation platform. Instead of asking one AI and hoping for the best, Legion makes five models debate your question through four rounds before synthesizing a final answer.

The Problem with Single-Model AI

Every AI model has blind spots. ChatGPT confidently states incorrect facts. Claude hedges when it should be direct. Gemini oversimplifies complex topics. Grok injects humor where you want substance. DeepSeek excels at reasoning but misses nuance.

When you ask one AI a question, you're betting that its particular strengths match your particular need—and that its particular weaknesses won't matter this time.

Power users know this. They maintain multiple AI subscriptions. They copy-paste the same question across different chat windows. They manually compare answers, trying to triangulate the truth. It works, but it's tedious.

A Better Approach: Make Them Debate

What if instead of you comparing AI answers, the AIs compared each other's answers? What if they could critique, challenge, and refine their responses before you ever see them?

That's Legion Mode. Here's how it works:

1. Independent Answers: Five AI models (Claude, GPT-4o, Gemini, Grok, and DeepSeek) answer your question independently, without seeing each other's responses.
2. Cross-Examination: Each model reads the others' answers and critiques them. They identify errors, gaps, weak reasoning, and unsupported claims.
3. Refinement: Armed with peer feedback, each model revises its answer—defending valid points and incorporating legitimate criticism.
4. Synthesis: A final response combines the consensus, highlights key insights, and notes any remaining disagreements.

The result isn't just an average of five answers. It's a refined answer that's been stress-tested by multiple perspectives.

Why This Works

AI models catch each other's mistakes. Claude notices when GPT hallucinates a fact. GPT spots when Claude is being unnecessarily cautious. Gemini points out when others miss the broader context.

It's the same reason peer review works in science, why courts have opposing counsel, and why companies have boards instead of singular leaders. Multiple perspectives, properly structured, produce better outcomes.

Three Ways to Use Legion

Not every question needs a four-round debate. That's why we built three modes:

• Single Mode: Pick one AI. Fast and simple for quick questions. (20 tokens)
• Parallel Mode: Query all five AIs at once, see answers side-by-side. You compare. (100 tokens)
• Legion Mode: Full four-round deliberation with synthesis. (500 tokens)

Try It Free

We're launching today with a free tier: 600 tokens, enough to run a few Legion queries or a dozen single-model queries. No credit card required.

If you find it useful, subscriptions start at $9.99/month—less than a single ChatGPT Plus subscription, but with access to five models that debate each other.

What's Next

This is just the beginning. We're working on:

• Mobile apps for iOS and Android
• BYOK (Bring Your Own Keys) for users who want to use their own API credits
• Enterprise features for teams and organizations
• Additional models as they become available

We'd love to hear what you think. Try it out and let us know what questions you throw at it.

Many minds. One answer.
