Cerebras
AI inference on wafer-scale chips — 1000+ tokens/second
What is Cerebras?
Cerebras is a cloud-based AI inference platform built on proprietary wafer-scale chip technology designed to deliver exceptionally fast token generation, often exceeding 1000 tokens per second. Rather than relying on traditional GPU clusters, the service uses a unified chip architecture that minimises latency, making it particularly suited for real-time applications where response speed matters. The platform operates on a freemium model, allowing users to experiment with the free tier before paying for production workloads.
Access is provided via a simple web interface and API, so developers can integrate Cerebras inference into applications without managing hardware infrastructure. The service appeals to organisations building latency-sensitive features like live chatbots or translation tools, researchers prototyping models quickly, and cost-conscious teams that want high-speed inference without large capital expenditure. It competes on speed and efficiency rather than breadth of models.

Pros & Cons
Advantages
- Extremely fast token generation reduces latency in real-time applications
- No hardware investment needed; purely cloud-based service
- Free tier enables experimentation without committing budget
- Proprietary chip design offers performance advantages over standard GPU inference
- Simple API makes integration into existing projects straightforward
- Particularly valuable for use cases where sub-second response times are essential
Limitations
- Smaller model library compared to established providers like OpenAI or Anthropic
- Fewer integrations and third-party tools available in the ecosystem
- Newer company with smaller community and less extensive documentation
- May have capacity constraints during periods of high demand
- Pricing at scale could become costly for very high-volume production use
- Less mature track record for evaluating long-term reliability and service stability
