@hackproduct9: Anthropic didn’t just release a new model. They introduced a new mental model. For years, the conversation was: 🧠 Ask AI a question ⚡ Get an answer Fable 5 and Mythos 5 shift the focus toward: 🎯 Give AI a goal ⏳ Let it work for hours 📦 Come back to completed work The interesting part isn’t that Fable 5 is better at coding. The interesting part is that Anthropic created a new capability tier: Mythos. Think of it as: Haiku → Sonnet → Opus → Mythos And for the first time, a Mythos-class model is available publicly through Fable 5, while Mythos 5 remains available to vetted organizations with fewer restrictions. (TechCrunch) My biggest takeaway: The skill gap for AI engineers is changing. Less focus on: • Prompt tricks • Chat interfaces • One-shot outputs More focus on: • Agent design • Context engineering • Evaluation systems • Tool orchestration • Long-running workflows The next frontier isn’t better answers. It’s longer autonomy. Save this cheat sheet for Q3 planning. Follow @hackproduct for practical AI engineering breakdowns. ##AIEngineering##Claude##Anthropic##LLM##Agents
