What is MegaBrain University?
Free MegaBrain guides on running AI agents (Claude Code, Codex, Hermes Agent, OpenClaw, OpenWork, OpenCode, Kilo Code) on Claude, GPT, Gemini and open models with one API key, and on what those agents can do for a business.
Which agent should I pick?
For an assistant in Telegram, WhatsApp or Slack with scheduled jobs: Hermes Agent or OpenClaw. For documents and files without coding: OpenWork. For software development: Claude Code on Claude models, Codex on GPT-6, or OpenCode and Kilo Code on any model.
Do I need Anthropic, OpenAI or Google accounts?
No. One MegaBrain key reaches Claude, GPT, Gemini, Grok, Kimi, GLM, DeepSeek, Qwen and MiniMax. You change models by changing the ID; the key and base URL stay the same.
How do I pay?
Pay as you go: each request is paid at the model’s price from a prepaid balance you top up by card. No subscription. Prices are in the model catalog.
