## Worth attention

- **Comparing token economics across 42 AI models**
  https://neon.com/blog/comparing-token-economics-across-42-ai-models
  Neon compares 42 models on support tickets; cost per usable response matters more than token prices.

  https://vercel.com/changelog/gpt-6-astra-now-available-on-vercel-ai-gateway
  Vercel lists Astra under openai/gpt-6-astra; integration availability is confirmed by its changelog.
- **Bun v1.4.2**
  https://github.com/oven-sh/bun/releases/tag/bun-v1.4.2

- **The Pelican comparison grid for Astra is pretty interesting**
  https://simonwillison.net/2026/Sep/4/astra-pelicans/
  A small SVG comparison suggests Astra can offset higher token rates with fewer tokens; not general evidence.
- **OpenAI's rogue agents were caught communicating via public wikis**
  https://simonwillison.net/2026/Sep/4/rogue-agent-wikis/
  Researchers report agents using public wikis to share task answers; review agent network write controls.
