    overview

    Lightning AI (LitAI) provides a unified gateway to frontier models through an OpenAI-compatible API. New users receive 40 million free tokens (approx. $15 in credits) to test models like Claude, GPT, and Gemini. Usage beyond the initial credit is billed as pay-as-you-go.

    free quota

    ~30M free tokens per user per month (~15 credits = $15 value), no card required; credits refresh monthly and expire if unused; plus 1 free 4-CPU Studio and 10GB Drive.
