OpenRouter's free tier gives you 50 requests a day until you spend $10. Groq gives 14,400 on its 8B model. Both numbers are from the official docs.
On published daily volume Groq's free tier is far larger than OpenRouter's — 14,400 requests per day versus 50 — but the two are not really competing on the same axis. OpenRouter sells breadth of model choice behind one key; Groq sells speed and headroom on a short model list. Below are both providers' own numbers, checked against their documentation on 26 July 2026.
OpenRouter's free model variants (any model ID ending in :free) are limited by lifetime credit purchases, not by your current balance:
| OpenRouter free models | RPM | RPD |
|---|---|---|
| Under $10 purchased (all time) | 20 | 50 |
| $10 or more purchased (all time) | 20 | 1,000 |
Source: OpenRouter API limits documentation. The distinction matters more than it looks. A positive balance is not enough — the platform tracks what you have ever spent. A brand-new account testing free models gets 50 requests per day, which one enthusiastic debugging session will exhaust before lunch.
Groq is currently the only major free provider still publishing a full per-model table. Verbatim from its rate-limit docs:
| Model | RPM | RPD | TPM | TPD |
|---|---|---|---|---|
| llama-3.1-8b-instant | 30 | 14,400 | 6,000 | 500,000 |
| llama-3.3-70b-versatile | 30 | 1,000 | 12,000 | 100,000 |
| openai/gpt-oss-120b | 30 | 1,000 | 8,000 | 200,000 |
| qwen/qwen3.6-27b | 30 | 1,000 | 8,000 | 200,000 |
| whisper-large-v3 | 20 | 2,000 | — | — |
The 288x gap between 50 and 14,400 requests per day is real but it compares OpenRouter's entry state against Groq's best model. Two fairer readings:
So the accurate statement is narrower than the headline: Groq is dramatically more generous if a small fast model does your job, and roughly comparable if it does not.
Model breadth. OpenRouter fronts hundreds of models from many vendors behind one key and one billing relationship, including proprietary models Groq does not host at all. If your work involves evaluating models against each other, that catalogue is worth more than any rate limit. Groq's list is short by design — the speed comes from running a narrow set of models on its own hardware.
They are also complementary in a way that is easy to miss: Groq's ceiling is per-model, OpenRouter's is per-account. Hitting one does not imply hitting the other.
Both expose OpenAI-compatible chat-completions endpoints, so the only differences your code sees are the base URL, the model identifier, and which error arrives when you run out. That is a small enough surface to abstract away entirely.
freelm pools OpenRouter, Groq, Gemini, Cerebras, NVIDIA NIM and Mistral behind a single call, retries on the next provider when one returns 429, and opens a circuit breaker rather than hammering a provider that is already refusing you:
pip install freelm
With both providers in the pool, Groq absorbs the bulk of small-model traffic while OpenRouter covers the models Groq does not host — and neither one going down takes your application with it. Setup is in the freelm documentation, and the wider provider landscape is covered in our review of free OpenRouter alternatives.
Q: Is Groq's free tier better than OpenRouter's?
A: On published daily volume, yes, and by a wide margin. OpenRouter caps free-model use at 50 requests per day until you have purchased $10 of credits, after which it rises to 1,000 per day. Groq publishes 14,400 requests per day for llama-3.1-8b-instant with no purchase requirement. OpenRouter's advantage is not volume — it is breadth of model choice behind one key.
Q: How many requests per day does OpenRouter's free tier allow?
A: 50 per day if your lifetime credit purchases are under $10, and 1,000 per day once you have bought at least $10 of credits. Both share the same 20 requests-per-minute ceiling. The threshold is measured against historical purchases, not your current balance.
Q: Which Groq model has the highest free daily limit?
A: llama-3.1-8b-instant at 14,400 requests and 500,000 tokens per day. Moving to llama-3.3-70b-versatile drops that to 1,000 requests and 100,000 tokens per day.
Q: Should I use both OpenRouter and Groq together?
A: Usually yes. They fail in different ways and at different times, so a client that routes across both survives either one rate-limiting you.
