Goodbye Claude, Hello Pi

A longtime Claude Code user is switching to the open source harness Pi after accumulating frustrations. Claude Code only lets one session connect to the IDE at a time, a bug reported since December 2025 and closed as a duplicate. The author counts 244 Claude Code releases this year, with over three-quarters changing the system prompt or tool descriptions. Despite trimming 80% of the system prompt, the default Bash tool description still runs almost 3,000 tokens. The author calls Claude Code a product without strong direction and says Pi has been smooth sailing since the first few days.

The End of AI Frontiers

Large language models remain far less efficient than biological brains at learning, representing knowledge, and planning, the post argues. A child hears roughly one token per second, reaching a billion tokens only after 31 years, while GPT-4-class models reportedly use four orders of magnitude more data. The Phi model series, trained on 10 trillion tokens, still trails GPT-4 along most axes. A Portia spider plans prey-catching behavior with a brain a million times smaller than a human's, and squirrels recall cached food after months, suggesting that existing models may be far less representationally and memory efficient.

Claude Code's creator says better prompts need just 3 things, so I tested his approach

Bối cảnh của bài viết khám phá liệu chúng ta có đang quá tư duy hóa việc tạo prompt hay không. Nguyên nhân kỹ thuật được nêu ra là một phương pháp đơn giản chỉ cần 3 yếu tố: context, instruction, và input, được đề xuất bởi nhà sáng tạo Claude Code. Hệ quả khi áp dụng phương pháp này là việc tạo prompt hiệu quả trở nên dễ dàng hơn nhiều so với những cách phức tạp trước đây. Điều đáng học là ngay cả những AI model mạnh nhất hiện nay như Claude 3 hay GPT-4 vẫn phản ứng tốt với prompt có cấu trúc đơn giản này.

Bài viết này giúp bạn hiểu ra cách đơn giản hóa việc tạo prompt hiệu quả chỉ với ba yếu tố cơ bản.
