Microsoft has significantly boosted the capabilities of its Copilot AI assistant by upgrading the "Think Deeper" feature with OpenAI's latest o3-mini-high model. This upgrade effectively provides all Copilot users, regardless of subscription status, with access to advanced AI reasoning capabilities previously exclusive to paid ChatGPT Pro users. The o3-mini-high model, known for its efficiency and intelligence, allows Copilot to tackle complex queries with greater depth and accuracy.This move marks a significant step in democratizing access to powerful AI tools. Initially, Microsoft had introduced the "Think Deeper" feature, powered by OpenAI's o1 models, with usage limits. However, due to positive user feedback, these limits were removed, and now, the underlying model has been upgraded to the more efficient o3-mini-high. This enhancement enables Copilot to deliver fresher insights and more relevant answers, keeping pace with the rapidly evolving world of AI.OpenAI's o3-mini model, including the high setting, is designed to provide comparable intelligence to the earlier o1 models, but with improved speed and cost-effectiveness. By integrating this model into Copilot, Microsoft is offering a compelling alternative to ChatGPT, which has seen significant user adoption.Despite providing free access to advanced AI models, Microsoft faces challenges in user acquisition for Copilot. The company has resorted to promotional tactics within its Bing search engine, particularly when users search for rival AI assistants, demonstrating its commitment to expanding Copilot's user base. The update to the "Think Deeper" feature is a strong move that could potentially shift the competitive landscape in the AI assistant market.
