OpenAI API
Last reviewed: 2026-05-23
Our take
OpenAI is the default building block for GTM AI workflows. We use it directly for high-volume cheap dispatch (GPT-4o-mini) and reasoning-heavy tasks (o3). Pair with Anthropic Claude Sonnet for long-context analysis where Claude beats GPT-4o consistently. For GTM teams, OpenAI's Realtime voice API is the breakout — replaces Demodesk for AE-coaching prototypes.
Who it's for: Any GTM team building AI workflows directly. Engineers + RevOps automating.
Pricing
Custom
Pay-per-token. GPT-4o input $2.50/M, output $10/M. GPT-4o-mini $0.15/$0.60. o3 reasoning model premium. Realtime API per minute.
