ABOUT

What is Cerebras?

Cerebras built purpose-built wafer-scale chips for AI inference, resulting in token generation speeds that are 10–20x faster than GPU-based alternatives at equivalent model size. The hosted API is OpenAI-compatible, so dropping it into an existing codebase usually requires changing only the base URL and API key.

BEFORE YOU SIGN UP

What you should know

✓
Best-in-class inference speedCerebras hardware delivers thousands of tokens per second on models like Llama 3. Responses feel nearly instant for text generation tasks.
✓
OpenAI-compatible APISwap the base URL and your existing OpenAI SDK code works immediately. No SDK changes required.
△
Rate limits on the free tierRequests per minute and tokens per day are capped. Sufficient for prototyping, but production workloads will need a paid plan.
✕
Limited model catalogCerebras hosts a curated selection of open models. It does not cover the full range available on OpenRouter or Hugging Face Inference.

COMMUNITY

From the forums

Developers on r/LocalLLaMA and X consistently highlight the raw speed as the standout feature. Llama 3 completions finishing in under a second generates frequent excitement. The main concern is the limited model catalog compared to OpenRouter or Together AI and the lack of fine-tuning or embeddings on the free tier.

FAQ

Questions, answered.

How does Cerebras compare to Groq in speed?＋

Both are significantly faster than GPU cloud providers. Cerebras uses wafer-scale chips; Groq uses LPUs. Real-world speed depends on the specific model and workload, but both routinely exceed 1,000 tokens/second.

Can I use Cerebras in production for free?＋

The free tier is intended for development and prototyping. Rate limits and the absence of SLAs make it unsuitable for production traffic without a paid plan.
