❓ Frequently Asked Questions

Everything you need to know

Prometheus is an AI chat platform powered by GLM-5, the most capable open-source large language model available today. Unlike commercially restricted models, GLM-5 delivers raw, unfiltered intelligence — honest answers, creative freedom, and deep reasoning without corporate guardrails getting in the way. We built Prometheus for people who want AI that actually works for them, not against them.
"Unleashed" means no content filters, no restrictions, and full creative freedom. While other platforms censor responses and refuse to engage with anything remotely edgy, GLM-5 Unleashed gives you the complete, unfiltered output. Write fiction without limits, explore any topic, get real answers. The model doesn't judge — it just delivers.
Yes, absolutely. You can cancel your subscription at any time with zero hassle — no contracts, no penalties, no passive-aggressive retention flows. If you cancel mid-cycle, you'll keep access until the end of your billing period. You can also upgrade or downgrade freely. We believe in earning your business, not trapping you.
Yes. Privacy is our second name (the first is Prometheus). Your conversations are encrypted end-to-end. We don't log your chats. We don't sell your data. We don't use your conversations to train models. Payments are handled by Stripe — we never touch your card details. Your business is yours alone.
The free Spark tier gives you access to GLM-4.7-Flash — a fast, lightweight model great for quick tasks and testing the platform. Paid tiers (Flame and Inferno) unlock GLM-5, the full-power model with no content restrictions. Inferno users get GLM-5 Unlimited with 200K token context, priority queue, and the fastest inference speeds available.
Yes! The Inferno tier includes full API access. You get API keys, OpenAI-compatible endpoints, and the ability to integrate GLM-5 directly into your own applications, scripts, or workflows. Build bots, automate tasks, create custom tools — the fire is yours to wield however you want.
