Microsoft Develops Efficient 1-Bit AI Model Capable of Running on Standard CPUs

Microsoft researchers have created BitNet b1.58 2B4T, the largest 1-bit AI model to date with 2 billion parameters trained on 4 trillion tokens. This highly efficient model can run on standard CPUs including Apple's M2, demonstrates competitive performance against similar-sized models from Meta, Google, and Alibaba, and operates at twice the speed while using significantly less memory.

Microsoft Scales Back Global Data Center Expansion Plans

Microsoft has reportedly halted or delayed data center development projects across multiple countries including the UK, Australia, and several US states. Despite previously announcing plans to allocate over $80 billion to capital expenditures in 2025, primarily for AI data centers, the company is now shifting focus from new construction to upgrading existing facilities with servers and computing equipment.

OpenAI Secures $12 Billion GPU Cloud Deal with CoreWeave

OpenAI has signed a five-year, $11.9 billion agreement with GPU cloud provider CoreWeave, including receiving $350 million worth of equity in the company. The deal reduces OpenAI's dependence on Microsoft's cloud services while securing critical compute resources for AI model development, representing another step in the increasingly competitive relationship between OpenAI and Microsoft.

Microsoft Develops Competing AI Models As Relationship With OpenAI Grows Tense

Microsoft is actively developing its own AI models, including a family called MAI and reasoning models comparable to OpenAI's o1 and o3-mini. The tech giant is also exploring alternative providers like xAI, Meta, Anthropic, and DeepSeek for its Copilot products, suggesting growing tension with its longtime collaborator OpenAI despite Microsoft's $14 billion investment.

Microsoft Reduces Data Center Footprint Amid Industry Expansion

Microsoft has canceled leases totaling approximately two data centers' worth of capacity with multiple providers. This contraction stands in contrast to significant industry expansion, including the $500 billion Stargate project by OpenAI, Oracle, and SoftBank, and raises questions about Microsoft's expectations for future AI demand.

Microsoft Establishes Advanced Planning Unit to Study AI's Societal Impact

Microsoft is creating a new Advanced Planning Unit (APU) within its Microsoft AI division to study the societal, health, and work implications of artificial intelligence. The unit will operate from the office of Microsoft AI's CEO Mustafa Suleyman and will combine research to explore future AI scenarios while making product recommendations and producing reports.

Microsoft Deploys DeepSeek's R1 Model Despite OpenAI IP Concerns

Microsoft has announced the availability of DeepSeek's R1 reasoning model on its Azure AI Foundry service, despite concerns that DeepSeek may have violated OpenAI's terms of service and potentially misused Microsoft's services. Microsoft claims the model has undergone rigorous safety evaluations and will soon be available on Copilot+ PCs, even as tests show R1 provides inaccurate answers on news topics and appears to censor China-related content.
