Inflection Trims the Stack: Claude 4.5 Sonnet and the Cost Curve
A field report on tool-first agents and what it changes for small studios.
The interesting question is not whether Vercel v0 works. It does. The interesting question is what teams do with it once the novelty wears off.
Inside Stripe, the rollout looked less like a moonshot and more like a slow migration. A pilot, a champion, a quiet expansion, a budget line.
Eval harnesses, once an afterthought, are becoming the most important piece of code in many AI projects. Klarna's team treats theirs the way an SRE team treats a runbook.
Ramp has been quietly running pricing analysis through Cursor for months. The results are unglamorous and, for that reason, more interesting than another benchmark chart.
What OpenAI actually shipped with DeepSeek V4 is less a single capability and more a cluster of small, compounding improvements — the kind that only show up when you put a real workflow on top.

What Google DeepMind actually shipped with Llama 4 is less a single capability and more a cluster of small, compounding improvements — the kind that only show up when you put a real workflow on top.
Inside Snowflake, the rollout looked less like a moonshot and more like a slow migration. A pilot, a champion, a quiet expansion, a budget line.
None of this guarantees a clean story. Meta FAIR could ship a model next month that rearranges the assumptions in this piece. But the direction of travel, for now, is clear enough to plan around.
