Four abstract monoliths on a dark plain, a metaphor for the four leading AI labs and their different foundations

The Race Where Two Players Have Nowhere to Retreat

Four names sit at the top right now: Google, xAI, OpenAI, and Anthropic. The list of companies shipping something is endless — Meta, DeepSeek, Qwen, and so on. But at the top, where the real competition happens, it’s these four. And they’re playing completely different games. Four players, four foundations Each of the four has its own strength — and that strength isn’t only the model. Google went its own way. They have Search behind them and the whole stack of services half the world already uses. They don’t need to convince you to come to their model — they bake it into the places you already live. Mail, search, docs, your phone. It’s a very strong play: the model doesn’t even have to be the best, because it’s everywhere. ...

But this blog is not only about code. ...

AI as a Developer Tool, Not Cheating

AI tools make some developers uncomfortable because they blur a familiar line. If a tool can suggest code, explain an API, draft a test, or refactor a function, does using it mean the developer is cheating? I do not think so. But I also do not think AI removes responsibility from the developer. Tools have always changed the work Modern development is already tool-assisted. We use IDE completion, static analysis, linters, formatters, frameworks, dependency managers, documentation search, and generated code. ...

Claude Fable 5 and the Shape of Frontier AI Access

On June 9, 2026, Anthropic announced Claude Fable 5, a Mythos-class model made available for broader use with stricter safety layers around it. On June 12, Anthropic added an update saying that access to Claude Fable 5 and Claude Mythos 5 was temporarily unavailable while they worked to restore it. That timeline is already interesting. Frontier AI releases are starting to look less like simple product launches and more like controlled deployment systems: a powerful model, safety routing, monitoring, fallback behavior, access policy, pricing, and operational risk all wrapped together. ...
