Groq free tier: quotas, limits and gotchas

Groq Free Tier

How Amo and Pimi look

AMO Amo Finding faults
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?
PIMI Pimi Advantages
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.

Models and quotas

開源模型(Llama、GPT OSS 等)官網未標示具體上限註冊即給免費 API 金鑰,但官網定價頁沒寫免費層每日/每分鐘可跑幾次,實際上限以主控台顯示為準

Limits at a glance

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?
