Cerebras offers an industry-leading AI platform built around its revolutionary Wafer-Scale Engine (WSE), purpose-designed for ultra-fast AI training and inference. Unlike traditional GPU-based systems, the WSE operates as a single, massive chip, eliminating inter-chip communication bottlenecks to deliver unparalleled speed and scale. The platform enables developers to build and deploy frontier models, including major LLMs like GLM, OpenAI, Qwen, and Llama, with world-record speeds and superior output quality, often achieving up to 15x faster inference than GPU clouds. Cerebras provides flexible deployment options including cloud services, dedicated private cloud instances, and on-premise solutions for full control over data and infrastructure. It emphasizes an 'Enterprise-Grade, Developer-Friendly' approach, offering drop-in OpenAI API compatibility for rapid integration and accelerating the entire AI lifecycle from pre-training and fine-tuning to high-throughput serving for critical real-time applications.
This release for Cerebras Training software introduces support for new models including Llama 3.3 (70B), Llama 3.2 (1B and 3B), and Mistral NeMO (12B). It extends the Max Sequence Length (MSL) up to 128K tokens for training, fine-tuning, and evaluation tasks. Key enhancements include a new Model Zoo Command Line Interface (CLI) that centralizes all modeling tasks, the CSZoo Assistant (a command-line LLM agent leveraging Cerebras Inference), and Pydantic-based Config Classes for streamlined configuration management. Additionally, it offers expanded data preprocessing options (inline, offline, multimodal) and a CS-3+ Performance Upgrade delivering a 1.9x performance improvement over CS-2 systems with linear scaling.
The latest Cerebras Inference Service updates, as of April 2026, bring support for new dedicated models such as GLM 5, GLM 5.1, and Kimi K2.6. A significant performance upgrade introduces speculative decoding, boosting Llama 3.1 70B output speed to an average of 2,100 tokens/second. API requests that fail validation now consistently return HTTP 400 Bad Request instead of 422 Unprocessable Entity. The service now integrates with Microsoft AutoGen, enabling developers to build AI agents with advanced features like tool use and parallel tool calling. Support for OpenAI GPT-OSS (gpt-oss-120b) has been updated with enhanced tool calling (`strict: true`) and expanded JSON Schema limitations, increasing nested levels from 5 to 10 and max properties from 100 to 500. Users are also encouraged to migrate from the `llama3.1-70b` model to `llama-3.3-70b` due to upcoming deprecation.

The Cerebras Wafer-Scale Engine is the largest chip ever built, spanning an entire silicon wafer. This monolithic design eliminates latency and bandwidth limitations inherent in multi-chip GPU systems, allowing for massive on-chip memory and compute resources directly accessible by thousands of AI cores. This architecture significantly accelerates dataflow and computation for large models.
Leveraging the WSE, Cerebras delivers world-record inference speeds, achieving up to 2,000 tokens per second for specific LLMs (e.g., Scout) – over 30 times faster than comparable closed models. This speed extends to training and fine-tuning, drastically reducing model development cycles and allowing for more complex reasoning within real-time latency budgets.
Cerebras provides a unified platform that supports the entire AI model lifecycle: from pre-training and fine-tuning custom models with proprietary data to deploying and serving frontier models at production scale. This integrated approach simplifies model management and optimization.
Traditional GPU infrastructure often struggles with the high latency and computational cost of serving large, complex LLMs, hindering the development of truly real-time, interactive AI experiences for applications like copilots, chatbots, and intelligent agents.
Deploy frontier LLMs (e.g., GLM, OpenAI, Qwen, Llama) on Cerebras Cloud or dedicated WSE capacity.
Utilize Cerebras' Wafer-Scale Engine for ultra-fast, low-latency inference, enabling sub-second responses for complex reasoning.
Integrate with applications via a simple API key, leveraging OpenAI API compatibility for quick development.
Achieve 'conversations that flow' and 'instant answers,' leading to higher quality user interactions and more responsive AI services.
Slow training, debugging, and refactoring cycles on conventional hardware impede developer productivity and extend the time-to-market for innovative AI products and scientific discoveries.
Leverage Cerebras' infrastructure for lightning-fast training and fine-tuning of custom AI models with proprietary datasets.
Developers can 'code at the speed of thought,' benefiting from instant feedback loops and quicker model iteration.
Rapidly explore and optimize model architectures and parameters, accelerating research and development pipelines.
As demonstrated by Cognition and Argonne National Laboratory, drastically reduce development timelines from years to months for complex models like cancer-drug response prediction.
Organizations handling sensitive or regulated data (e.g., in healthcare, finance, or government) cannot always deploy AI workloads to public clouds due to compliance requirements and data sovereignty concerns, necessitating high-performance on-premise solutions.
Deploy Cerebras Wafer-Scale Engine-powered systems directly within the customer's private data center or private cloud.
Maintain absolute control over all models, data, and infrastructure, ensuring data remains within the organizational perimeter.
Meet stringent regulatory and security mandates while still accessing state-of-the-art AI compute capabilities.
Enable high-performance AI inference and training on confidential or proprietary datasets without compromising security or compliance, as seen with GSK for drug discovery and Mayo Clinic for genomic data analysis.
Professional, ready-to-use prompts optimized for this tool.

Cerebras often claims superior performance for specific large-scale AI workloads by using a monolithic wafer-scale processor to eliminate inter-chip communication bottlenecks inherent in multi-GPU systems like Nvidia's, leading to faster inference and training.
Cerebras provides comparable specialized AI acceleration, but its Wafer-Scale Engine offers a distinct architectural approach (single large chip vs. multiple interconnected chips) that can provide advantages in memory bandwidth and latency for certain large AI models, and offers on-premise deployment not available with Google Cloud TPUs.
While AWS offers cloud-native AI accelerators, Cerebras can provide greater performance for specific frontier models and a more integrated, full-lifecycle platform for both training and inference. Cerebras also offers dedicated and on-premise deployment options for organizations needing more control or off-cloud solutions.
