THE BRIEFING

Anthropic's Opus 4.7 quietly got more expensive to run despite flat list pricing—token counters reveal higher context-window costs. OpenAI released a lightweight multi-agent framework for Python, while TSMC's cautious earnings suggest the chip giant isn't betting big on sustained AI demand. Meanwhile, GitHub's fake-star economy and enterprise adoption stories paint a maturing, messier landscape.

First token counts reveal Opus 4.7 costs significantly more than 4.6 despite Anthropic's flat pricing

Simon Willison's token counter tool exposes what Anthropic didn't advertise: Opus 4.7 consumes more tokens per request than 4.6, meaning higher real-world costs even though per-token pricing stayed flat. This is a classic cloud pricing sleight-of-hand, and developers are not amused. Watch for Anthropic to either clarify or face mounting pressure to revert the change.

openai/openai-agents-python — A lightweight, powerful framework for multi-agent workflows

OpenAI quietly dropped a native multi-agent orchestration framework for Python—trending hard on GitHub. This is OpenAI formalizing what the community has been hacking together with LangChain and AutoGPT. The fact that it's lightweight and opinionated suggests OpenAI sees agents as infrastructure, not science experiments. If you're building agents, this is now the reference implementation.

TSMC Earnings, New N3 Fabs, The Nvidia Ramp

Ben Thompson flags that TSMC's earnings call was notably cautious—leadership isn't acting like they believe the AI chip boom is sustainable. They're building N3 fabs, but the tone suggests hedging, not conviction. If the world's chipmaker-in-chief is skeptical, that's a data point worth remembering when VCs pitch infinite GPU demand.

Changes in the system prompt between Claude Opus 4.6 and 4.7

Anthropic updated Claude's system prompt between 4.6 and 4.7, and Willison's diff reveals subtle shifts in how Claude reasons and responds. Anthropic remains the only major lab publishing these prompts, which is both rare transparency and a gift to prompt engineers.

The RAM shortage could last years

Supply constraints on high-bandwidth memory (HBM) could persist for years. This is the AI infrastructure bottleneck no one wants to talk about—GPUs are useless without RAM.
