The frontier gap in web development between proprietary and open source models nearly closed this quarter, until big releases from @AnthropicAI and @OpenAI last week causing it to snap back open. From a peak of +150 points in late 2025, the proprietary lead compressed to just approx. +10 points by early Q3 2026 as open source models made large gains. With Claude Fable 5.1 and GPT-6 Astra, the proprietary frontier jumped back to nearly 1,800 pts while open source held near 1675 pts widening the gap to +120 points.

The history is shorter, and the gap has moved faster: the proprietary lead rose +100 points, then compressed sharply through spring 2026. Today, the lead is around +40 points. 🔗 View Quoted Tweet 💬 6 🔄 4 ❤️ 80 👀 7842 📊 11 ⚡
