Is Thesys worth the price?
Thesys offers a fair pricing structure, especially with its generous Free tier providing 5K API calls and $10 in LLM credits.
The Build tier at $49/month for 25K calls is competitive for small teams, though the per-call overage of $0.002 can add up. The Grow tier at $499/month for 500K calls offers better value for scaling teams with a lower overage cost.
