Frequently Asked Questions
Everything you need to know. Start building with confidence.
Agent Builder pricing has four tiers: Free, Build, Grow, and Custom. Each plan includes a set number of C1 API calls per month plus a tiered set of platform features. LLM token costs are billed separately at your model provider’s rates — passed through directly with no markup.
No. Every plan includes unlimited team members. You only pay based on API usage, not how many people are on your team.
On the Free plan, your agents stop responding once you hit 3,000 calls. On Build and Grow you can continue beyond your included calls at $0.002/call (Build) or $0.001/call (Grow) — no hard cutoff, so your end users are never interrupted. Custom plan limits and overage rates are negotiated.
Build is for small teams shipping their first production agents — 25K calls/month, custom styling, whitelabeling, and bring-your-own-identity. Grow steps up to 500K calls/month at a lower per-call overage, plus mid-market features like RBAC, audit logs, custom domains, conversation analytics, BYOK, SSO/SAML, and priority Slack support.
Bring Your Own Identity (BYOI) lets you connect your own auth provider so end users log in with your identity system — available on Build and above. Bring Your Own LLM Key (BYOK) lets you use your own provider API keys for full control over model spend — available on Grow and above.
Yes. Thesys is SOC 2 Type II, ISO 27001, and GDPR compliant. Your users’ conversations are private to your organization and are never used to train models. Grow adds RBAC, audit logs, and SSO/SAML. Custom adds dedicated infrastructure, custom data retention, and HIPAA compliance support.
Custom is for organizations that need negotiated usage limits, dedicated infrastructure or VPC deployment, custom development, dedicated support, and enhanced compliance guarantees. Pricing is tailored to your needs — contact sales for a quote.
