This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Claude Code lets us choose between different models (Opus, Sonnet, Haiku) and effort levels (low, medium, high, xhigh, max). The core idea is simple: not every task deserves the same horsepower. Renaming a […]

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. In the newer versions of Claude, a tip that pops up in the terminal says: “Run tasks in the cloud while you keep coding locally.” At first glance, this sounds like marketing fluff.

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. According to Anthropic (therefore, take these numbers as a direction, not as a promise), Claude Opus 5.5 works at the level of Fable 5.1 on most jobs, and costs 40% less to run

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Claude has amnesia. Not the poetic kind. The official documentation says it plainly: “Each Claude Code session begins with a fresh context window.” You spent four hours with it yesterday. You explained why

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Anthropic’s figure above, $150-250 per month, is the average across enterprise deployments. A heavy user is a different story. Some Delphi users investigated what their subscription would cost at API list prices. One
This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. In Windows, Ctrl+C means Copy. In a terminal, it means Stop. In Claude Code, it means whichever one you did not want. I press Ctrl+C by reflex. In Claude Code, one stray press

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Claude is verbose. Ask it to fix a one-line bug and you get three polite paragraphs before the fix arrives. Every one of those words is an output token, and output tokens cost
This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Skills and sub-agents are both ways to extend Claude’s behavior, and they’re easy to confuse at first. They look similar on the surface but work very differently under the hood. A skill is

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Skills are addictive. Each one solves a real annoyance, each one takes ten minutes to write, and none of them feels expensive. Then one day you run /doctor and it tells you that

This article is one chapter of my book Delphi in all its glory – AI-assisted development, the fifth book of the series. Somewhere around Opus 5 a new complaint started showing up everywhere: the model got smarter and the answers got harder to use. Not wrong. Harder to use. You ask a small question and
Everything, from voidtools, finds any file on my disks while I am still typing its name. Claude Code has its own file finder, Glob, and next to Everything it feels slow. So I told Claude to switch. It took one small download, one line in CLAUDE.md, and learning a few traps that return nothing without

Opus 5 will not be shortened by lowering the effort level. A Claude Code skill that re-says the last answer in plain words, without re-deriving it and without dropping a single caveat.

Anthropic publishes three “agentic coding by effort level” charts for Opus 5 but prints no numbers on them. I measured the dots. On two of the three, max effort scores lower than xhigh while costing more.

I ran my AI code-review pipeline twice on the same Delphi unit: once with Claude Opus 4.8 agents, once with Claude Fable 5 agents. Same byte-for-byte prompts, same file state (restored between runs), models verified from the agents’ own transcripts. The result was not what the hype predicts. The setup The target: frmTestMain.pas (482 lines)

I just published a new GitHub repository: Awesome-AI-For-Delphi. It is a curated list of tools, libraries, MCP servers, and resources for using AI with Delphi. Think of it as a single place to discover everything that exists at the intersection of AI and Pascal/Delphi development. The list covers: MCP Servers — let Claude Code and

On a very “intelligent” discussion on en.delphipraxis.net, an AI zealot tried to convince me that nowadays the AI CAN count how many r’s are in the word strawberry. You know… the old meme. What the AI-defenders don’t understand is that even if the AI can give you a correct answer to that question, it is

Using Claude Code for Delphi — What I Learned Writing a Book About It What started as a frustrated blog post became a 280-page book. Here’s the story. In early 2026, a post on Delphipraxis claimed that one hour of development with Claude Code was worth a full day of solo programming. Bold claim. I
I open-sourced my AI client. For the moment it only supports Google Gemini, but it can be easily extended to other LLMs (Claude, OpenAI, etc.) by subclassing TLLMObject. What it does This Delphi library lets your application talk to the Gemini API without you having to fight with HTTP, multipart upload sessions, JSON body assembly,
