AI Tech Weekly

## AI Infrastructure and Strategic Partnerships

Recent weeks have underscored the intensifying race for AI compute capacity. On September 22, chipmaker NVIDIA and OpenAI announced a landmark letter of intent to deploy at least 10 gigawatts of NVIDIA’s next-generation data-center systems for OpenAI’s AI infrastructure, with NVIDIA committing up to $100 billion in progressive investments tied to each gigawatt deployment. The partnership marks one of the largest-ever pledges to AI compute and cements NVIDIA’s central role in powering frontier models, setting the stage for the next era of AI research and applications from superintelligence to real-time multimodal agents ([reuters.com](https://www.reuters.com/business/nvidia-invest-100-billion-openai-2025-09-22/?utm_source=openai)).

Complementing NVIDIA’s direct investment, CoreWeave, a specialized cloud provider for GPU workloads, expanded its AI partnership with OpenAI on September 25 by signing a new contract worth up to $6.5 billion—bringing their total collaboration to $22.4 billion this year. This expansion supports OpenAI’s “Stargate” infrastructure project targeting 10 gigawatts of compute, illustrating how multiple hardware and cloud players are rallying to meet the surging demand for training and serving advanced AI models ([reuters.com](https://www.reuters.com/business/coreweave-expands-openai-pact-with-new-65-billion-contract-2025-09-25/?utm_source=openai)).

## Corporate AI Ecosystem Moves

Tech incumbents continue to diversify their AI stacks. On September 24, Microsoft announced it will integrate Anthropic’s Claude models—Claude Sonnet 4 and Claude Opus 4.1—into its Microsoft 365 Copilot assistant. This shift allows enterprise users to choose between OpenAI’s GPT models and Anthropic’s offerings within tools like Researcher and Copilot Studio, reflecting Microsoft’s strategy to avoid overreliance on any single AI supplier and to broaden capabilities by incorporating third-party models even when hosted on competing clouds like AWS ([reuters.com](https://www.reuters.com/business/microsoft-brings-anthropic-ai-models-365-copilot-diversifies-beyond-openai-2025-09-24/?utm_source=openai)).

Meanwhile, Meta Platforms has also been active on the AI product front. On September 23, Meta announced that its Llama large language model would be made available to U.S. allies in Europe and Asia—including governments and institutions in France, Germany, Italy, Japan, South Korea, NATO, and EU organizations—following U.S. federal approval for Llama’s use by government agencies. Meta is partnering with Microsoft, AWS, Oracle, and Palantir to support deployments, aiming to foster innovation and reduce dependency on rival AI providers ([reuters.com](https://www.reuters.com/business/retail-consumer/metas-llama-be-made-available-us-allies-europe-asia-2025-09-23/?utm_source=openai)).

Adding to its AI content offerings, Meta unveiled “Vibes” on September 25—a dedicated AI-powered short-video feed accessible via the Meta AI app and meta.ai website. Vibes enables users to generate, remix, and share fully AI-created or AI-enhanced videos, with built-in cross-posting to Instagram and Facebook stories and reels. The platform taps third-party video-generation models and underscores Meta’s push to drive engagement and ad revenue through generative AI experiences ([reuters.com](https://www.reuters.com/business/meta-unveils-new-ai-video-feed-vibes-2025-09-25/?utm_source=openai)).

## Government, Regulation, and Legal Developments

AI’s rise has drawn legal scrutiny and regulatory action. On September 25, a U.S. federal judge preliminarily approved a $1.5 billion copyright settlement in a class-action lawsuit against Anthropic, brought by authors alleging the company unlawfully used pirated books to train its Claude models. While the judge had earlier deemed the training uses “fair,” he found Anthropic liable for storing millions of unauthorized books in a centralized library. The settlement—if granted final approval after author notifications and claims processes—could set a precedent for similar cases against OpenAI, Microsoft, and Meta, signaling a new phase in holding AI developers accountable for training-data practices ([reuters.com](https://www.reuters.com/sustainability/boards-policy-regulation/us-judge-approves-15-billion-anthropic-copyright-settlement-with-authors-2025-09-25/?utm_source=openai)).

In parallel, Elon Musk’s xAI secured a significant government contract on September 25: the U.S. General Services Administration (GSA) will purchase licenses for xAI’s Grok 4 and Grok 4 Fast chatbots at a nominal rate of $0.42 per agency under its “OneGov Strategy.” The 18-month deal—set to run through March 2027—reflects federal efforts to streamline AI procurement and diversify vendor options, although Grok has faced criticism for occasional biased or erroneous outputs. xAI engineers will assist with deployment and security standards, joining a cohort of suppliers that includes OpenAI, Meta, and Google ([reuters.com](https://www.reuters.com/world/us/musks-xai-provide-grok-chatbot-us-federal-agencies-2025-09-25/?utm_source=openai)).

However, xAI has also turned to the courts: on September 25, the Washington Post reported that xAI filed a lawsuit in the U.S. District Court for Northern California accusing OpenAI of stealing trade secrets through former xAI employees who allegedly transferred proprietary code and business plans. xAI claims these hires were orchestrated to undermine its competitive position—a move OpenAI disputes. The suit highlights the high stakes and fierce rivalries shaping the AI landscape ([washingtonpost.com](https://www.washingtonpost.com/technology/2025/09/25/musk-xai-openai-lawsuit-trade-secrets/?utm_source=openai)).

## Talent and Workforce Expansion

As competition heats up, AI firms are scaling their global footprints. Anthropic announced plans on September 26 to triple its international workforce and quintuple its applied AI team in 2025, citing surging demand for its Claude family of models—now used by over 300,000 enterprise customers, 80 percent of whom are outside the U.S. New offices are slated to open in Tokyo, Dublin, London, and Zurich, with country leads being recruited across Asia-Pacific, Europe, and beyond. This expansion reflects Anthropic’s ambition to rival entrenched players like OpenAI and Microsoft in key global markets ([cnbc.com](https://www.cnbc.com/2025/09/26/anthropic-global-ai-hiring-spree.html?utm_source=openai)).

## Research, Product Releases, and Emerging Tools

On the product front, OpenAI continues refining its developer tools. On September 23, the company updated its Model Release Notes to announce that GPT-5-Codex—a variant of GPT-5 optimized for coding tasks—became generally available in the Responses API. GPT-5-Codex offers fast interactive edits, extended autonomous processing for complex jobs, multimodal support (including images and screenshots), and real-time collaboration features across terminals, IDEs, and mobile environments. This release further solidifies Codex’s role as a versatile AI coding companion for developers worldwide ([help.openai.com](https://help.openai.com/en/articles/9624314-model-release-notes%23.eot?utm_source=openai)).

Microsoft, too, is piloting new AI experiences within its products. In mid-September, the company launched Windows AI Labs—a preview program allowing select users to test experimental AI features in core Windows applications starting with Microsoft Paint. Separately, Edge’s AI roadmap was detailed by Microsoft AI chief Mustafa Suleyman, who described plans to evolve Edge into an “agentic browser” where Copilot handles routine tasks like price comparisons and content synthesis, all as opt-in features that respect user privacy and choice ([timesofindia.indiatimes.com](https://timesofindia.indiatimes.com/technology/tech-news/microsoft-launches-windows-ai-labs-for-testing-experimental-ai-features/articleshow/124061860.cms?utm_source=openai)).
