DeepRails suits developers shipping LLM features who want an API that detects and corrects hallucinations, plus teams wanting a fixed-quote custom AI build, starting with a free Playground tier.
DeepRails has a free Playground tier with no credit card and no ticket support. Basic is $49 per month for 1 seat with $50 free credits and calls from $20 per 1k. Pro is $149 per month for 10 seats with $150 free credits, from $18 per 1k calls, custom guardrails and HallucinationSafe certification.
Enterprise is $499 per month with unlimited seats, $500 free credits and calls from $15 per 1k. Consulting is a fixed quote after a discovery call. An annual option saves 2 months on Basic. Prices checked on 2026-10-01.
