Microsoft Shifts AI Strategy: Confirms Plan to Reduce Reliance on OpenAI

Microsoft is embarking on a major strategic realignment in artificial intelligence, with its AI chief confirming plans to significantly reduce reliance on OpenAI, according to multiple industry reports. While the two companies have maintained a high-profile partnership since 2019 — including a $13 billion investment by Microsoft and exclusive licensing of OpenAI’s GPT models — internal documents and executive statements now indicate a deliberate shift toward in-house AI development. This transition, described as a move toward "AI self-sufficiency," marks a pivotal moment in the evolution of corporate AI strategy and could reshape the competitive landscape of generative AI.

According to MSN Technology, Microsoft’s leadership has internally acknowledged that the current partnership model, while initially beneficial, is no longer sustainable as a long-term foundation. The company aims to build and deploy proprietary AI models that match or exceed the performance of OpenAI’s offerings without external dependencies. This includes accelerating development of its own models under the Microsoft Phi and Phi-3 series, as well as expanding its Azure AI infrastructure to support end-to-end training and inference capabilities.

Seeking Alpha reports that the restructuring of the Microsoft-OpenAI deal, finalized in late 2025, included revised terms that reduced Microsoft’s financial exposure to OpenAI’s cash-burning operations. OpenAI, despite its technological lead, has struggled with profitability and has increasingly sought capital infusions from Big Tech. Microsoft’s decision to pivot away from this funding dependency signals a broader industry trend: major tech firms are moving from partnership models to vertical integration in AI.

While Microsoft will continue to offer ChatGPT via its Copilot interface for the foreseeable future, internal teams are already training next-generation models on Azure’s supercomputing clusters using proprietary datasets. Sources within Microsoft’s AI research division confirm that the company has recruited over 500 additional AI researchers since 2024, many from top academic institutions and rival firms like Anthropic and DeepMind. This talent surge is directly tied to the internal goal of releasing a flagship model — internally codenamed "Aurora" — by late 2026, which would rival GPT-5 in capability while being fully owned and operated by Microsoft.

The move also has implications for OpenAI’s business model. With Microsoft no longer acting as a primary financial backer, OpenAI is reportedly exploring alternative funding avenues, including potential IPO plans and partnerships with non-tech entities. Meanwhile, Microsoft’s shift is expected to strengthen its position in enterprise AI markets, where clients increasingly demand data sovereignty, compliance control, and vendor independence.

Analysts note that this transition is not abrupt but phased. Microsoft will maintain its current integration with OpenAI’s models for at least 18 months to ensure customer continuity. However, internal memos obtained by industry insiders suggest that future updates to Microsoft Copilot will increasingly prioritize Azure-hosted models over OpenAI’s API. This gradual migration minimizes disruption while maximizing long-term control.

For investors and enterprise clients, Microsoft’s strategy signals a maturation of AI from experimental collaboration to core infrastructure. The company’s ability to deliver high-performance AI without external dependencies could set a new standard for the industry — one where technological leadership is defined not by partnerships, but by self-reliance.
