What counts as a rep (token)?
One token ≈ 4 characters of text. A typical coaching session exchanges 2,000–8,000 tokens. At Standard tier, a full week of daily check-ins costs under $0.10.
Can I switch trainers mid-program?
Yes. All six models read from the same training log. Swap at any time — your history, PRs, and notes travel with you.
Is output really billed separately?
Yes, just like the underlying APIs. Input (your messages + context) and output (the coach's replies) have different per-token rates. We show you a running cost estimate in the session view.
Do I need a credit card to try it?
No. Sign up free and explore the dashboard. You only enter payment when you send your first message to the AI Coach. First 10K tokens are on us.
What is Self-host and do I need a server?
Self-host means you run DeepSeek V3 or Llama 405B on your own hardware. Forge gives you the integration layer; you supply the GPU. A capable local machine or a cloud VM works fine.
Is there a rate limit on Frontier?
No hard limits on Frontier. Claude Opus and GPT-5 Pro operate at priority queue level. Heavy users (>50M tokens/month) get a dedicated capacity allocation by default.
