Engineering with Small Language Models

Can efficient AI be powerful without requiring massive compute resources or costly cloud subscriptions?

Engineering with Small Language Models answers this question by showing how Small Language Models (SLMs) deliver high-performance natural language processing in resource-constrained environments. While large language models dominate headlines, SLMs offer a compelling alternative: fast inference, low memory usage, and flexible deployment on CPUs, mobile devices, edge hardware, and affordable GPUs. With tools like Hugging Face, PyTorch, and advanced techniques such as quantization and federated learning, you can build production-ready AI systems that are lightweight, secure, and scalable.

This comprehensive guide takes you through the entire SLM lifecycle, from design and training to optimization and deployment. Written for developers, AI engineers, and data scientists, it provides clear, practical workflows backed by real-world code and case studies. You’ll learn how to fine-tune models with parameter-efficient methods like LoRA, compress them using 4-bit quantization and pruning, and deploy them on devices like Raspberry Pi or smartphones. The book also addresses critical topics like privacy, bias mitigation, and compliance, ensuring your AI systems are ethical and production-ready.

What’s Inside:

• Setting up and running SLMs with Hugging Face and PyTorch
• Fine-tuning with LoRA, QLoRA, and adapters for domain-specific tasks
• Compression techniques: 4-bit/8-bit quantization, GPTQ, AWQ, and pruning
• Exporting models to ONNX, TensorFlow Lite, and Core ML for edge deployment
• On-device inference for Raspberry Pi, Android, iOS, and IoT devices
• Federated learning and differential privacy for secure, privacy-preserving AI
• Building scalable inference APIs with FastAPI and TorchServe
• Kubernetes, serverless, and autoscaling strategies for cloud deployment
• Ethical AI: bias mitigation, interpretability, and accessibility best practices
• Case studies in chatbots, healthcare, finance, and IoT
• CI/CD pipelines, monitoring, and performance optimization workflows
• Appendices with scripts, datasets, and troubleshooting guides
