About

On this channel we think, plan, and build. Right now on the channel, we're on the path to evolve into Agentic engineers. Engineers that build software that works for them while they sleep. Here are principles of my engineering philosophy and ideologies this channel holds as facts. - Avoid hype, focus on real valuable tools, technology and products. - Build real products. There are enough news, hype, trend channels. Let's make something real. - Listen to feedback but always think for yourself. - Use the best technology for the job period full stop. - Keep learning, forever. - Do what you share. I don't share anything on this channel I'm not betting on with my time, energy and money. - Cancel out the noise and focus on the signal of value creation. - Great things happen in the flow. Look for it everyday. I'm not the perfect programmer, designer, or creator but to succeed you don't have to be perfect, you just have to try, over and over in success or failure.

Video Description

Can Haiku 4.5 Actually COMPETE with Sonnet 4.5? NOPE - BUT the Speed AND Cost Advantage is REAL Speed? Check. Price? Check. Performance? We're about to find out. Is the new Claude Haiku 4.5 the model that changes everything for agentic coding, or is Sonnet 4.5 still the undisputed champion? 🔥 RESOURCES FOR YOUR ENGINEERING: - Multi-Agent Observability: https://github.com/disler/claude-code-hooks-multi-agent-observability - Haiku 4.5: https://www.anthropic.com/news/claude-haiku-4-5 - Tactical Agentic Coding: https://agenticengineer.com/tactical-agentic-coding?y=aA9KP7QIQvM In this agentic coding video, we pit Claude Haiku 4.5 against Claude Sonnet 4.5 in a head-to-head agentic coding showdown. Discover how haiku 4.5 delivers blazing speeds and costs a third of Sonnet while analyzing whether this tactical agentic coding approach actually works. Our multi-agent observability dashboard reveals exactly what these models can do side by side, exploring the real-world implications of AI coding with cheaper, faster compute. 🛠️ Watch as we deploy these models through four critical challenges: file summarization with view and TypeScript discovery, feature planning with UI themes and timers, live feature implementation, and multi-agent documentation processing. Using indydevdan's tactical agentic coding framework, we'll showcase how multi-agent systems and coding agents operate in parallel, breaking down every tool call and observability metric that matters for AI engineers and software developers. 💡 For developers and AI engineers focused on maximizing efficiency, this video explores the multi agent system architecture powering Claude Code. Learn how to leverage Haiku as a scouter model for simple tasks, understand the true cost-speed-performance trade-offs, and discover when to deploy Haiku sub-agents instead of Sonnet for your agent observability needs. This is essential viewing for anyone building with AI agents in production environments. 🌟 Whether you're exploring agentic engineering or scaling multi-agent systems, this analysis of Claude Haiku 4.5 versus Sonnet 4.5 provides the tactical knowledge you need. Packed with real-time metric comparisons, cost breakdowns, and practical examples of coding agents in action, this video is your guide to the future of AI-assisted development. 🎓 Key Takeaways: Haiku 4.5 Capability: Understanding what haiku can and cannot do compared to Sonnet performance Multi-Agent Systems: See real-world multi agent implementation and coordination in action Cost Optimization: Calculate when to use cheaper models and when you need Sonnet's power Claude Code Integration: Deep dive into Claude Code features like plugins, skills, and multi-agent observability Speed Comparison: Witness the actual token throughput and response times side by side Tactical Agentic Coding: Learn proven patterns for scaling agents across your codebase 👨‍💻 Ready to master agentic coding and transform your workflow with AI agents?
