Bottom line: Groq (GroqCloud) is not a chatbot app — it is a very fast API for running open AI models, and its Free plan is genuinely usable: 30 requests a minute, with daily caps that vary by model. For developers prototyping an app, bot, or coding assistant, it is one of the most generous free inference offers available. The catch: the token ceilings bite sooner than the request counts suggest.
Free-plan details checked October 16, 2026, against Groq’s published rate-limit documentation and pricing coverage. This is a research-based review; we do not claim hands-on testing.
What does Groq do?
Groq runs large language models on its own custom LPU chips, built for speed. Through the GroqCloud console and API you can call open models — Llama, OpenAI’s open-weight GPT-OSS models, Qwen, and Groq’s own Compound systems — plus Whisper for speech-to-text. The API is OpenAI-compatible, and a browser playground lets you try prompts without code. The headline feature is raw pace: responses stream noticeably faster than the same models on ordinary GPU hosting, which makes chatbots, voice assistants, and coding tools built on Groq feel snappy.
What is actually free on Groq?
The Free plan costs $0 and does not require a credit card to start. Rate limits apply per organization, so extra API keys do not multiply your allowance. The pattern across the main chat models is:
- 30 requests per minute on the principal chat models.
- 1,000 requests per day on widely used models such as GPT-OSS 120B and 20B and Qwen3-class models, with a much higher daily request allowance on small guard models.
- Token ceilings: roughly 8,000 tokens per minute and 200,000 tokens per day on those flagship open models — this is usually the limit you hit first.
- Speech included: Whisper speech-to-text is part of the free offer, metered separately in audio requests (reported at 2,000 a day).
Read that token math honestly: 200,000 tokens a day is plenty for a personal assistant or a day of prototyping, but not enough to serve a public app — and a coding agent dragging large files into every request can burn it in a handful of turns.
What does the paid Developer plan add?
Adding billing moves you to pay-per-token Developer pricing with substantially higher rate limits and batch processing. Published per-token prices are low — the cheapest models start at a few cents per million input tokens — so paying buys headroom and reliability, not different models. Enterprise adds custom limits and support.
Pros and cons of Groq’s free plan
Pros
- Real free plan with strong models, not a time-limited trial
- Extremely fast responses — speed is the product, and it shows
- OpenAI-compatible API makes switching and testing easy
- Speech-to-text through Whisper is included on the free offer
Cons
- Daily token ceilings (about 200K on top models) cap serious agent work
- Open models only — no native GPT, Claude, or Gemini flagship access
- Limits vary by model and change over time; you must check your console
- It is a developer tool: no polished consumer chat app
Who is Groq best for?
Developers prototyping AI features and indie hackers building chat or voice tools who care about latency. If you just want to chat in a browser, use a free chatbot; if you want an API key that makes open models feel instant, start here.
Frequently asked questions
Is Groq really free?
Yes. The Free plan is $0 with rate limits (30 requests a minute, model-dependent daily caps). Paid Developer usage is billed per token.
Does Groq require a credit card for the free plan?
No. You can create an account and an API key and start on the free limits without adding payment details.
Which models can I use free on Groq?
Open-weight models: Llama-family, GPT-OSS 120B and 20B, Qwen, Groq Compound, and Whisper for speech-to-text. The catalog changes as models launch and retire.
Is Groq the same as Grok?
No. Groq is an inference company with custom LPU chips; Grok is xAI’s chatbot. The names are confusingly similar, the products are unrelated.
Verdict: The best free way to feel how fast open models can run. Generous for prototypes, honest about its ceilings — watch the daily token budget, not the request count.
