I Paid for a Top-Tier Model. It Got Dumber and Marked Me

Codex GPT-5.5 clusters reasoning at 516; Claude Code secretly marks Chinese users. When cloud AI silently degrades, open-weight self-hosting is the hedge.
Fable 5 ran a hardcore 15-hour task for $420. The model is genuinely stronger. But after June 22 it's out of the Coding Plan subscription, and API rates push costs up by an order of magnitude. Access to the best intelligence has become a pure money problem.
Opus 4.8 disappointed me on research and engineering tasks, so I moved all that work to GPT 5.5. Looking back, this isn't just Claude's problem. From NVIDIA and AMD nearly going bankrupt to Zhipu falling behind and bouncing back, the top models have always traded places. Don't bet on who's strongest—bet on who's still at the table.
The Gemini 3.5 Flash launch barely talked about intelligence; Zhipu’s GLM-5.1 High-Speed edition hit 400 token/s. Both tell the same story—once inference speed crosses that 5× threshold, the model unlocks an entirely different product category.
Today I went to the AMD Developer Conference in Shanghai. Over 2,000 people packed the venue, and AMD gave one of its two developer awards to a non-coder who used an AI agent to rewrite a project in Rust. A year ago everyone worried about demand; six months later, all anyone asks is: 'Got more supply?'

A friend asked where to start with Vibe Coding. Two paths: start from work, or start from your digital identity. The prerequisite is that what you put out must be the real you—the internet has memory, and the old tweets dug up on Kevin Hart were from ten years ago.
