AMA of course but here are the things people asked.
What model does it use?

It uses (As base GPT-OSS 120B heretic but fine-tuned and has specific GPU inference tunnings for abliteration) pingu-unchained model also can be accessible on https://pingu.audn.ai and https://platform.audn.ai (used specific model pingu-unchained-3-mcp)
How is it unlimited AI usage for flat $200 fee?
Most openclaw users choose mac mini or mac studio, the core problem with them actually they are not multi session friendly. Openclaw by nature spawns another and another agent and LLM costs roof so easily. Therefore we are proposing a shared GPU with isolated microVMs module. When you become a subscriber for that month you become a tenant at the same VM. Like we share apartments we can share 1 H100 based VM and it runs 7/24 and has all good things cloud computing offers. Backups, revisions, no data loss, recovering to an old state and more.
Is it open-source and is it always synced with OpenClaw?

Yes like Openclaw it's opensource and it's actual fork of OpenClaw. We constantly sync the new version on Github you can see the history here: https://github.com/audn-ai/penclaw We are looking for maintainers before the open release of our Platform section which has Filesystem, Isolated micro-vm, meta-claw (Cursor Like Agent Retrofit), cloud terminal, marketplace (One-click Mcp and skills deploy). If you are interested please send an email to ozgur@audn.ai
Is it secure?

A third party red teaming cybersecurity team found it's vulnerabilities before everyone else so we patched them all. But if you use penclaw do find exploits on penclaw.ai we ofc would be happy.
Is there anything interesting done with penclaw AI?
Penclaw has an MCP/skills connection called audn sec qa. We used penclaw to conduct automated attack taxonomies on voice and text AI agents using that MCP. AI took the prompts and discovered the agents by having a conversation and conducted prompt injection and similar attacks.
Usual OpenClaw features what about them?
