Di chapter na di main knowledge wey you need to understand di new AI wey dey work sharp-sharp and how to use am for different computer setups. ## Chapter Plan and How to Learn Step by Step ### **[Section 1: Microsoft Phi Model Family Fundamentals](./01.PhiFamily.md)** Dis first section go talk about Microsoft Phi model family wey dey perform well even though e no dey use plenty computer power. E go cover: - **How Dem Take Design Am**: How Microsoft Phi family start from Phi-1 reach Phi-4, and di "textbook quality" training wey dem use plus di scaling wey dey happen when you dey use am. - **Efficiency-Focused Design**: How dem make di model dey use less parameters, fit work for different things like pictures and text, and how e dey work well for CPU, GPU, and edge devices. - **Special Skills**: Di different types like Phi-4-mini-reasoning for maths, Phi-4-multimodal for vision-language tasks, and Phi-3-Silica wey dey work inside Windows 11. Dis section dey show say you fit get better performance and efficiency if you sabi train and design di model well. ### **[Section 2: Qwen Family Fundamentals](./02.QwenFamily.md)** Di second section go talk about Alibaba Qwen models wey be open-source and dey perform well. E go focus on: - **Open Source Power**: How Qwen models start from Qwen 1.0 reach Qwen3, with training wey cover 36 trillion tokens and fit speak 119 languages. - **Smart Reasoning Design**: How Qwen3 dey use "thinking mode," mixture-of-experts, and di special types like Qwen-Coder for coding and Qwen-Math for maths. - **Flexible Deployment**: How di model fit range from 0.5B to 235B parameters, wey fit work for mobile phones or big enterprise setups. Dis section dey show how open-source AI fit dey accessible and still perform well. ### **[Section 3: Gemma Family Fundamentals](./03.GemmaFamily.md)** Di third section go talk about Google's Gemma models wey dey focus on multimodal AI and research. E go cover: - **Innovation Through Research**: How Gemma 3 and Gemma 3n dey use Per-Layer Embeddings (PLE) and dey optimize for mobile devices. - **Multimodal Power**: How e dey combine vision and language, audio processing, and function calling for better AI experience. - **Mobile Optimization**: How Gemma 3n dey perform well with small memory size and parameters. Dis section dey show how research fit bring better AI wey everybody fit use. ### **[Section 4: BitNET Family Fundamentals](./04.BitNETFamily.md)** Di fourth section go talk about Microsoft BitNET wey dey use 1-bit quantization for super-efficient AI. E go cover: - **Quantization Revolution**: How di model dey use ternary weights {-1, 0, +1} to make am fast and save energy. - **Optimized Inference**: How di bitnet.cpp implementation dey work with special kernels and fit work for different platforms. - **Green AI**: How e dey help save energy and make AI deployment easy for everybody. Dis section dey show how quantization fit make AI dey fast and still perform well. ### **[Section 5: Microsoft Mu Model Fundamentals](./05.mumodel.md)** Di fifth section go talk about Microsoft Mu model wey dem design for Windows devices. E go cover: - **Device-Focused Design**: How di model dey work inside Windows 11 devices. - **System Integration**: How e dey improve Windows 11 functionality with native AI. - **Privacy First**: How e dey work offline and keep user data safe. Dis section dey show how specialized models fit make Windows 11 better while keeping privacy intact. ### **[Section 6: Phi-Silica Fundamentals](./06.phisilica.md)** Di last section go talk about Microsoft Phi-Silica wey dey work inside Windows 11 Copilot+ PCs with NPU hardware. E go cover: - **Efficiency Metrics**: How Phi-Silica dey perform well with low power consumption. - **NPU Optimization**: How e dey use Neural Processing Units for better performance. - **Developer Tools**: How e dey work with Windows App SDK and prompt engineering. Dis section dey show di latest way to use hardware-optimized language models for Windows 11. ## Wetin You Go Learn After you finish dis chapter, you go sabi: 1. **Model Design**: Understand di different ways to design SLMs and how e dey affect deployment. 2. **Balance Between Performance and Efficiency**: How to choose di right model based on di computer power and wetin you need am for. 3. **Deployment Options**: Di difference between proprietary models like Phi, open-source like Qwen, research-based like Gemma, and efficient ones like BitNET. 4. **Future Trends**: Wetin dey come next for AI and how e go affect deployment. ## How to Use Am Practically Dis chapter dey focus on how you fit use di models with: - **Code Examples**: Ready-made code wey you fit use for training, optimizing, and deploying di models. - **Performance Tests**: Compare di models based on speed, efficiency, and use cases. - **Security**: How to make sure di deployment dey safe and reliable. - **Framework Integration**: How to use di models with tools like Hugging Face Transformers, vLLM, ONNX Runtime, and others. ## Future Plans for Technology Di chapter go end with talk about: - **Model Design Growth**: How di design of efficient models dey improve. - **Hardware Development**: How new AI hardware dey change deployment. - **Ecosystem Growth**: How different models dey work together better. - **Enterprise Use**: How companies fit plan to use AI well. ## Real-Life Examples Each section go show how you fit use di models for: - **Mobile and Edge Devices**: How to deploy AI for devices wey no get plenty resources. - **Business Use**: How to use AI for business intelligence, automation, and customer service. - **Education**: How AI fit help for learning and creating content. - **Global Use**: How AI fit work for different languages and cultures. ## Standards for Technical Excellence Dis chapter dey focus on how to make sure di models dey ready for production with: - **Optimization Skills**: How to use quantization and manage resources well. - **Performance Monitoring**: How to collect metrics and check performance. - **Security**: How to protect privacy and follow compliance rules. - **Scaling**: How to plan for more computational needs. Dis chapter na di base wey you need to sabi how to deploy SLMs well. E go give you di theory and practical skills wey you need to make di models work for your organization and prepare for di future. Di chapter dey connect di latest AI research with how to use am for real life, showing say modern SLMs fit perform well, dey efficient, dey cheap, and dey good for di environment. --- **Disclaimer**: Dis dokyument don use AI translet service [Co-op Translator](https://github.com/Azure/co-op-translator) do di translet.
