OpenAI's ChatGPT App Store Took Aim at Apple, But Results Lag So Far

Six months in, ChatGPT's app store has 300 integrations and partners are deliberately capping functionality to protect their own customer relationships. Instant Checkout signed 12 merchants out of millions before OpenAI scaled it back; sales tax collection still isn't built, the SDK is buggy, and developers report no usage data and an opaque approval process. The retreat from embedded checkout to app-based checkout to product discovery traces a company working backward from the transaction layer it never controlled.

Tokenmaxxing: When AI Productivity Becomes Productivity Theater

Token consumption became the week's central metric, and it measures exactly the wrong thing. One OpenAI engineer burned 210 billion tokens in a week; a Figma user ran up $70K in Claude usage through a $20/month account; Anthropic is offering $1,000 of compute inside $200 plans, subsidizing at roughly 5x. The leaderboards tracking this volume are Goodhart's Law applied to inference: the moment consumption becomes the proxy for productivity, consumption is what you get. The $25 economic theory pipeline and the Karpathy Loop running 700 experiments in two days are the same phenomenon from the other side — generation so cheap it exposes that evaluation is the only part of the stack nobody has built. Every SaaS platform offering AI at flat rate is running a margin time bomb; every enterprise treating token volume as a progress signal is one measurement framework away from discovering they've been optimizing for nothing.

The Karpathy Loop: Autonomous Agent Optimization as Research Pattern

Karpathy's autoresearch ran 700 experiments in two days on a 630-line codebase: the result matters less than the pattern. The Karpathy Loop (agent + single file + testable metric + time limit) is the atomic unit of constrained autonomous optimization, and it generalizes to any problem with a measurable output and a modifiable code surface. The real competitive shift isn't building better agents; it's designing better constraints, metrics, and stopping criteria: taste becomes the bottleneck, not compute.

Tokenmaxxing: When AI Productivity Becomes Productivity Theater

Roose names "tokenmaxxing" — engineers competing on internal leaderboards for token consumption — but buries the only question that matters: nobody measures output quality. One OpenAI engineer burned 210 billion tokens in a week; a single Anthropic user ran up $150K in a month. The leaderboards track input volume, not output value. This is lines-of-code metrics reborn: Goodhart's Law applied to AI inference. The sharper signal is a Figma user consuming $70K in Claude tokens through a $20/month account, revealing that every SaaS platform offering AI at flat rate is running a margin time bomb. The companies that win this cycle won't consume the most tokens; they'll have the best ratio of useful output to tokens spent. That measurement layer doesn't exist yet.
