Investing.com -- Claude AI is Anthropic’s suite of frontier large language models, designed for advanced reasoning and built with an emphasis on safety and reliability.

The company is expanding global access to these models after announcing new strategic partnerships with Microsoft and NVIDIA.

Anthropic’s lineup includes three widely used model families: Claude Opus, Claude Sonnet and Claude Haiku.

On Tuesday, Microsoft, NVIDIA and Anthropic announced new strategic partnerships.

Microsoft said as part of its partnership with the company, customers of Azure AI Foundry will now be able to access “Claude Sonnet 4.5, Claude Opus 4.1 and Claude Haiku 4.5,” describing them as part of a broader collaboration to bring Anthropic’s frontier AI to more businesses.

With this expansion, Claude becomes “the only frontier LLM model available on all three of the world’s most prominent cloud services.”

Claude Sonnet sits at the centre of the lineup. It is designed to offer a balance of power and efficiency, positioned between the lightweight Haiku and the flagship Opus model.

The partnerships announced this week revealed that Anthropic is scaling its “rapidly growing Claude AI model on Microsoft Azure, powered by NVIDIA,” committing to purchase $30 billion of Azure compute and up to 1 gigawatt of additional capacity.

NVIDIA will work directly with Anthropic “to optimize Anthropic models for the best possible performance, efficiency and TCO,” while tuning future NVIDIA architectures for Claude workloads. NVIDIA and Microsoft plan to invest up to $10 billion and $5 billion, respectively, in Anthropic.

Microsoft will also continue supporting Claude across its Copilot products, including GitHub Copilot.
