PromptWizard is a task-aware prompt optimization framework developed by Microsoft. It employs a self-evolution mechanism that allows large language models (LLMs) to generate, critique, and refine their own prompts and examples, continuously improving through iterative feedback and synthesis. This adaptive approach enhances task performance through evolutionary instructions and contextually learned examples. The three key components of this framework include feedback-driven optimization, critique and synthesis of diverse examples, and self-generated Chain of Thought (CoT) steps. The significance of PromptWizard lies in its ability to significantly enhance LLM performance on specific tasks by optimizing prompts and examples to improve model performance and interpretability.

Phi-4 is the newest member of Microsoft's Phi series of small language models, featuring 14 billion parameters and excelling in fields requiring complex reasoning, such as mathematics. Phi-4 achieves a balance between size and quality by leveraging high-quality synthetic datasets, carefully curated organic data, and innovations in post-training. It represents a technological advancement in small language models (SLMs) by Microsoft, pushing the boundaries of AI capabilities. Phi-4 is available on Azure AI Foundry and will launch on the Hugging Face platform in the coming weeks.

Florence-2 is a high-performance visual foundation model developed by Microsoft, utilizing a prompt-based approach to handle a wide range of visual and vision-language tasks. This model can interpret simple text prompts and perform tasks such as image description, object detection, and segmentation. It is trained on the FLD-5B dataset, containing 5.4 billion annotations across 126 million images, demonstrating expertise in multi-task learning. Its sequence-to-sequence architecture allows for strong performance in both zero-shot and fine-tuning settings, proving to be a competitive visual foundation model.

PowerToys is a system utility suite launched by Microsoft, aimed at advanced users to enhance productivity and system experience. It includes a variety of practical tools, such as a color picker, window management, and file explorer plugins, to help users better manage their Windows systems.

Copilot+ PC, the latest AI-driven high-performance Windows PC launched by Microsoft, boasts a powerful new silicon chip capable of over 400 trillion operations per second, all-day battery life, and access to cutting-edge AI models. It empowers users to perform unprecedented tasks on their PC, such as quickly searching and recalling content on their PC via the Recall feature, generating and refining AI images almost in real-time on the device using Cocreator, and bridging language barriers by translating audio from over 40 languages into English with Live Captions.

Copilot Pro is a paid upgrade version of Copilot released by Microsoft. By providing prioritized access to the latest AI models such as GPT-4, it significantly enhances users' creativity and work efficiency. This service can be bundled with Microsoft 365 subscriptions and supports the direct use of Copilot features within Office applications such as Word and Excel, helping users draft documents, emails, and presentations much faster.

Deep Search is a new search feature introduced by Microsoft Bing, which leverages generative AI models such as GPT-4 to expand and understand complex search queries, providing more relevant and comprehensive search results. This feature can delve deeply into the web to find information unattainable by general searches. Key features include: understanding search intent, extending search terms; deeply searching related pages; and sorting results by relevance. It is suitable for cases where general searches are insufficient and more comprehensive and accurate answers are needed. Empowered by AI, it significantly enhances the quality of Bing search.
