Groq's free tier bills declared tokens, not generated ones, causing errors

Groq's free tier charges for the maximum number of tokens a user declares in a request, rather than the number of tokens actually generated. This can lead to "Request too large" errors even for small prompts if the declared `max_tokens` is high. The billing is based on a shared 8,000 tokens per minute (TPM) budget across all models, meaning a single large declaration can consume the entire minute's allowance. This behavior is particularly problematic for AI agents, which often include tool schemas in their prompts, leading to unexpected token consumption and errors. AI

IMPACT This billing model could negatively impact developers building AI agents on Groq's free tier, potentially increasing costs or causing unexpected errors.

RANK_REASON The item details a specific operational quirk and billing model of an existing AI inference service, rather than a new release or major industry shift.

    Groq's free tier bills the tokens you ask for, not the ones you get

    <p>I lost an afternoon to a 413 that made no sense. A twenty-token prompt, a model with a 131k context window, and Groq answering <code>Request too large</code>. The request was not too large. The number I had <em>declared</em> was.</p> <p>Here is the whole mechanism, plus a swee…
