The AI Supercomputer: Powering ChatGPT and Large Language Models

🔋Microsoft Azure has built an AI supercomputer to support large language models, such as ChatGPT, with hundreds of billions of parameters.

⚡️The AI supercomputer in Azure can train models that are even larger than GPT-3, such as Microsoft's Megatron-Turing with 530 billion parameters.

🌐Azure's specialized hardware and software stack enables the efficient training and inference of large language models at global scale.

🚀Project Forge, a containerization and global scheduler service, ensures reliable and uninterrupted training of AI models.

🔬Low Rank Adaptive (LoRA) fine-tuning technique allows efficient customization of foundational models for specific domains or datasets.

What is an AI supercomputer?

—An AI supercomputer is a specialized hardware and software infrastructure built to support the training and inference of large language models and other AI workloads at scale.

How large are the language models supported by Azure's AI supercomputer?

—Azure's AI supercomputer can train models with hundreds of billions of parameters, larger than GPT-3's 175 billion parameters. For example, Microsoft's Megatron-Turing has 530 billion parameters.

How does Azure ensure the reliability and uptime of the AI supercomputer?

—Azure uses Project Forge, a containerization and global scheduler service, to enable transparent checkpointing for uninterrupted training. It also collaborates with hardware partners to implement technologies like Checkpoint/Restore In Usermode (CRIU) for GPUs.

Can I customize a foundational language model for specific domains?

—Yes, Azure supports the fine-tuning of foundational models using techniques like Low Rank Adaptive (LoRA) fine-tuning. This enables customization for specific domains or datasets, such as healthcare or enterprise data.

Is the AI supercomputer available for Azure customers?

—Currently, Project Forge is being used for Microsoft services like GitHub Copilot. However, Microsoft is working on making it directly available to customers in the near future.
