Groq's API remains free in October 2026 — no credit card, no trial clock — gated only by rate limits that were tightened in late 2026. It is still the fastest way to run open models (Llama family, Qwen) at zero cost, thanks to Groq's LPU inference hardware: responses stream at hundreds of tokens per second, which makes free-tier experimentation feel like a paid tier.
Here are the exact mechanics as of October 1, 2026.
Last verified: October 1, 2026. Groq tunes quotas frequently; the console's rate-limits page always shows your live numbers per model and plan.
What the free tier includes
- Zero-cost access to the model catalog. Free-plan keys can call the production models — the Meta Llama 4 family, Qwen3, and Whisper for transcription. The catalog rotates as models deprecate; see console.groq.com/docs/models.
- No card, no expiry. The free tier is a standing plan, not a trial: it never converts to paid without you doing it explicitly.
- Rate limits in four dimensions: requests per minute (RPM), requests per day (RPD), tokens per minute (TPM) and tokens per day (TPD) — evaluated per model and per plan.
What tightened in 2026
Multiple developer reports through 2026 describe the same trajectory: the free tier's daily request ceiling dropped (to the order of a thousand requests per day, with some models lower), and the paid Developer plan took over as the "real usage" tier with limits on the order of 1,000 RPM and far higher token budgets. The practical reading:
- Free is for development, prototyping, personal projects — it remains generous for interactive use.
- The moment your workload is batch or production, Groq expects you on a paid plan. That's fair — the LPU speed is the product.
How to get a Groq API key (1 minute)
- Sign in at console.groq.com (Google account works).
- Go to API Keys → Create API Key.
- Copy the
gsk_…key — it's shown once. - Paste it into your tool. In SynthHires:
/space/models→ Groq card. It's encrypted locally with AES-256-GCM and never leaves your browser.
Every Llama-family model in the Space's model picker activates the moment the key lands.
Free tier vs Developer plan (directional)
| Dimension | Free plan | Developer plan |
|---|---|---|
| Price | $0 | Pay-as-you-go |
| Card required | No | Yes |
| Requests/minute | Low tens | ~1,000+ (per model) |
| Requests/day | ~1,000 | Effectively unlimited by plan design |
| Token budgets | Tight per-model TPM/TPD | Large per-model TPM |
| Best for | Prototyping, tinkering, learning | Production, agents, batch |
Exact numbers vary per model — treat this table as shape, not contract, and confirm in the console.
Is Groq's free tier still worth it in 2026?
Yes — with the right expectations. No other free tier combines this speed with open models: at hundreds of tokens/second, Groq free is the best "feels like real product" sandbox available. Stack it with Gemini's free Flash tier and OpenRouter's :free models and you can run serious experimentation at literally $0/month — see the full breakdown in our free AI API keys guide.
FAQ
Is the Groq API free in 2026?
Yes. The free plan requires no credit card and has no time limit; access is gated by rate limits (RPM/RPD/TPM/TPD per model). Limits were reduced during 2026 — the daily request ceiling is now on the order of a thousand requests per day depending on the model.
Which models can I use on Groq's free tier?
The production catalog at the time you call it — currently the Meta Llama 4 family, Qwen3, and Whisper for transcription. Check the live model list at console.groq.com/docs/models, because Groq deprecates and adds models continuously.
What is the Groq API key format?
Groq keys start with gsk_ — for example gsk_1a2B3c.... The Space auto-detects the provider from that prefix when you paste. If a key is rejected, regenerate it in the console and re-paste; keys are shown only once.
How fast is Groq, really?
Fast enough that speed is the product: Groq's LPUs stream open models at hundreds of tokens per second — an order of magnitude above typical GPU serving for many models. On the free tier you get the same speed with tighter volume caps.
Groq vs Gemini free tier — which should I pick first?
Both, they're complementary: Groq gives you speed on open models (Llama/Qwen), Gemini gives you Google's frontier Flash models. Keys take a minute each and stack in a BYOK workspace like SynthHires. Our Gemini free tier explainer covers Google's side.
Grab the gsk_ key, paste it, and you're streaming open models at $0 — the Get API keys guide has every other provider, and the October 2026 price table shows what paid inference costs when you outgrow free.
