Groq API免费额度指南2026
Groq以定制硬件上的惊人token速度闻名。免费额度让它成为2026年原型开发默认选择。
Groq API Free Tier 2026: The Fastest LLM Inference, Now With a Real Free Plan
Groq runs LLMs on custom LPU (Language Processing Unit) hardware, achieving output speeds of 1,000+ tokens per second on models like Llama 3.3 70B - an order of magnitude faster than GPU clouds. Its free tier has made it the default place developers prototype in 2026.
What the Free Tier Gives You (2026)
- Access to fast open models: Llama 3.3 70B, Llama 3.1 8B, Qwen2.5-72B, and others
- Generous rate limits for development (roughly 30 requests/minute on free)
- OpenAI-compatible API - swap base URL and key
- No credit card required to start
Getting Started
# 1. Sign up at console.groq.com, create an API key
# 2. OpenAI-compatible call
from openai import OpenAI
client = OpenAI(api_key="gsk_...", base_url="https://api.groq.com/openai/v1")
resp = client.chat.completions.create(
model="llama-3.3-70b-versatile",
messages=[{"role": "user", "content": "Explain RAG in 3 sentences."}]
)
print(resp.choices[0].message.content)
Speed Reality
| Model | Groq output speed |
|---|---|
| Llama 3.1 8B | 1,500+ tok/s |
| Llama 3.3 70B | 800-1,000 tok/s |
| Qwen2.5-72B | 700+ tok/s |
For comparison, typical GPU clouds deliver 50-150 tok/s on the same models.
Best Use Cases
- Agent loops - the speed makes multi-step tool calling feel instant
- Batch processing - summarize thousands of items quickly
- Streaming chat UX - output arrives faster than you can read
- Prototyping - free tier means zero-cost iteration
Limits to Know
- Free tier has lower rate limits and no SLA (production should use paid)
- Model list changes; check console for current offerings
- Context windows are competitive (128K on several models) but check per model
FAQ
Is Groq free forever? The free tier is ongoing with rate limits; paid tiers remove limits and add models.
Why is Groq so fast? LPU hardware is a deterministic architecture optimized for sequential token generation, unlike GPUs designed for parallel matrix math.
Groq vs together.ai vs OpenRouter? Groq for max speed and free prototyping; Together for fine-tuning + inference; OpenRouter for one-key access to every model.
