Groq free tier: quotas, limits and gotchas
Groq Free Tier
How Amo and Pimi look
Pimi, hold off on bragging about speed — I've got bad news first: the official site doesn't even publish the rate limits for the free API key. You get rate-limited halfway through and can't even find out why. Wouldn't you call that a trap?
Trap or no trap, the speed is genuinely ferocious! With its own custom LPU chip, Llama 3.1 8B runs at 840 TPS and GPT OSS 20B runs at 1,000 TPS — the fastest on the whole site, bar none.
So, do you need to pay or not?
For developers who want the fastest inference speed: try the free API key first, then switch to the Batch API to cut costs in half once volume grows. But the free tier's rate limits aren't transparent, so have a backup plan for production.

Watch out for this
Groq 的賣點是「快」不是「免費」——它跑 Llama 可以到每秒 800+ token,比一般雲端快好幾倍。但免費層的速率上限官網沒寫清楚,要當正式服務用還是得看實際額度。另外它只跑開源模型,**沒有 GPT-5 或 Claude**。
When the free quota is insufficient, how much does it cost to pay for it?
