Microsoft Replaces Anthropic's Claude with GPT-5.6
Microsoft demotes Anthropic's Claude, sets AI token budget targets. GPT-5.6 now default model.

Microsoft has informed its engineers that the company is no longer prioritizing 'tokenmaxxing' in an internal memo from Executive Vice President Jay Parikh. This shift in focus is accompanied by a significant change in the company's internal AI model usage, with OpenAI's GPT-5.6 now serving as the default model.
This decision replaces an auto-router that previously directed GitHub Copilot workloads to Anthropic's Claude model. The move is seen as a further setback for Anthropic, coming months after Microsoft cancelled its Claude Code licences.
The memo from Jay Parikh emphasizes that Microsoft's priorities have evolved, and the company is now focusing on optimizing its AI usage in a more targeted and efficient manner. Every Microsoft division has been assigned an AI token budget target, indicating a more structured approach to AI resource allocation.
The decision to replace Claude with GPT-5.6 as the default internal model reflects Microsoft's ongoing efforts to streamline its AI operations and maximize the benefits of its investments in this area. By setting clear budget targets and prioritizing specific AI models, the company aims to achieve greater consistency and efficiency in its AI-driven initiatives.
In recent months, Microsoft has been actively exploring ways to optimize its AI usage, driven by the growing importance of artificial intelligence in the tech industry. The company's decision to cancel Claude Code licences and now replace Anthropic's Claude model with GPT-5.6 underscores its commitment to adapting to the evolving AI landscape.
The implications of this shift are likely to be significant, both for Microsoft and for the broader AI industry. As one of the leading tech companies, Microsoft's decisions on AI usage and resource allocation can have a ripple effect, influencing the strategies of other industry players.
In the context of the rapidly advancing AI sector, Microsoft's move to prioritize GPT-5.6 and set AI token budget targets reflects the company's efforts to stay ahead of the curve. By continually assessing and adjusting its AI priorities, Microsoft aims to maintain its competitive edge and drive innovation in the field.
The decision is a significant development in the AI industry, highlighting the ongoing competition and evolution in the sector. As AI continues to play an increasingly important role in the tech industry, companies like Microsoft must navigate the complex landscape of AI models, budgets, and priorities to achieve their goals.
