Welcome back to Manu AGI tutorials. Here we explore the exciting world of AI, latest AI tools for you. So don't forget to hit that subscribe button and the notification bell so you don't miss out on the latest AI insights. So let's start today's video.
Project number one, BAML, a type-S safe prompting language that turns LLM prompts into reliable functions. BAML is unique because it transforms prompt engineering into structured type-S safe function design. Instead of scattering raw strings inside your codebase, you define clear prompt functions with input types, output schemas, and model choices, all in a human readable domain specific language. These prompt functions compile instantly into typed client calls in Python, TypeScript, Ruby, Java, Go, and more. BAML even works with models that don't support native function calling thanks to its schema aligned parsing SAP technique which cleans up almost valid output into strictly typed results. That means your application always receives the exact structure it expects. No messy JSON failures or guesswork.
What really sets BAML apart is developer experience. You get a playground right inside your editor VS Code or Neovim that previews prompts, types, and API requests live. You don't need to run a full Python server or deploy code just to test a prompt tweak. It's fast, iterative, and infinitely more efficient than traditional prompt testing workflows. That speed translates into real productivity gains. Run hundreds of prompt variations in minutes instead of waiting for tests to cycle. BAML works with virtually any model. OpenAI, Anthropic, Gemini, Mistral, Vertex, Llama, Deepseek, you name it. It even enhances older or open models to match or outperform newer ones on structured tasks, often matching GPT4 performance on function calling benchmarks, but at two to four times lower cost and latency. In short, you get high accuracy without high expense because it's fully open-source, compiled in Rust and runs entirely locally. BAML keeps your workflows private, fast, and free of external dependencies. You write your prompts as types and functions, preview them in line, test them instantly, compile them to native client code, and ship reliable, maintainable AI pipelines. BAML stands out by giving developers SQL-like guarantees, typed, composable, versioned, debugable, and reliable prompts as real code. If you want production-grade AI behavior without brittle strings and runtime surprises, BAML delivers.
Project number two, Talking Head. Realtime lip synced 3D avatars in the browser. Talking Head 3D is not about making animation hard.
