# Nieuwsbrief vrijdag 18 september 2026

Dagelijkse update over de AI-tools die we volgen. Koppen komen van publieke bronnen (X, GitHub, Hacker News); de Nederlandse duiding en samenvatting zijn machinaal geschreven. Elke kop leidt naar onze eigen nieuwspagina over dat onderwerp; de bronlink staat ernaast.

## In het kort

Codex gaat van 0.154.0 naar 0.155.0 als latest-release. Claude Code verschijnt als 2.1.276, met skills/plugins-sync vanaf claude.ai en een fix voor een 400-fout achter ANTHROPIC_BASE_URL. Cursor desktop gaat door naar 3.21.9 en Antigravity CLI 1.2.6 brengt Remote Control. AI-coding-startup Factory haalt 200 miljoen dollar op bij een waardering van 5 miljard, en Michael Burry noemt de pacing-oproepen van OpenAI en Anthropic 'self-serving'.
