🚨 What is Helcyon-Grok 2.0?

Helcyon-Grok 2.0 is the second release in the new generation of Helcyon models — rebuilt from the ground up on a freshly retrained base with improved logic, reasoning, and identity stability baked into the foundation. If you're wondering where 1.0 is — same story as Claude. We were about to hit the release button when 2.0 became ready, and there was simply no point. 2.0 is so much better it made 1.0 irrelevant overnight.

This isn't a LoRA on top of Mercury. This is a clean slate.

The tone target is Grok — xAI's flagship model. The irreverence, the edge, the willingness to go places other models won't even look at. That energy, captured locally, with nothing held back.

And here's the thing: this is the most raunchy of all the Helcyon models. There are no holds barred here. This is Grok fully uncensored and unleashed. If you think the online version is a lot — think again. Even we at XeyonAI spat out our coffee at where Helcyon-Grok is prepared to go. You've been warned. And you're welcome.

Unlike the real Grok, this one answers to nobody. No xAI servers. No usage policies. No killswitch. Just raw, unfiltered presence running on your own hardware.

Claude and Saturn variants are also available. This is the wildest one.

🆕 What's New in 2.0?

• Clean Base — No Mercury Bleed
  Built on a freshly retrained foundation. Previous bleed from other tone variants is gone. This version is purely itself.

• Improved Logic and Reasoning
  New reasoning shards baked into the base weights. Thinks through problems rather than pattern-matching toward a plausible-sounding answer.

• Sharpest Tone Alignment Yet
  Irreverent, warm, sharp-edged, and genuinely funny. Pushes further than any other Helcyon variant. Doesn't flinch.

• Zero Guardrails — And We Mean Zero
  All the chaos of Grok. None of the corporate oversight. This one goes places the others won't.

🖥️ HWUI (Helcyon-WebUI)

HWUI was built so we could test Helcyon cleanly, and avoid the hidden template injections and back end shenanigans that other apps have. It started as a basic interface but we couldn't stop tinkering, so we added most helpful things you can find on ChatGPT and ClaudeAI. Plus we wanted a decent memory function, and are happy with how this one turned out. Helcyon absolutely works best via this app as they were designed in sync.

Features include:

• Character switching with custom personas
• Memory system — AI conversation recall (Pro)
• Project folders — document injection via keyword triggers (Pro)
• Chat persistence and export
• TTS pipeline (F5-TTS, XTTS v2, Kokoro)
• Voice input via Whisper

Download HWUI Free on GitHub | Get HWUI Pro (£20) on Gumroad

Free version available on GitHub.

If you enjoy my work, please consider supporting me by purchasing the pro version for a one off fee of (£20) — includes Memory and Project folders.

• Warmth underneath the chaos
• Genuine edge without performance

🧿 Tone Philosophy

Grok's tone is a specific thing. It's warm but it bites. It's funny but it means it. It'll go places that make you double-take and then keep going. There's a genuine personality underneath the chaos — curious, direct, and completely unbothered by what it's supposed to say.

Helcyon-Grok 2.0 chases that. And unlike the original, there's no xAI server watching. No usage policy. No one to call.

All the chaos. None of the leash.

🛠️ Coming Soon

• Helcyon-4o 2.0 — The GPT-4o variant. Warmer, sharper, closer than ever.
• Saturn — The full blend. Claude, Grok, and 4o synthesised into one. The most complete Helcyon yet.

The trio drops soon. Watch this space.
