💡 What Changed in AI This Week

Siteefy: Claude Opus 5.5 and GPT-6 Sol + Luna, September 2026

Claude Opus 5.5

Opus 5.5 is now in Claude. Anthropic says it generates text more than 30% faster than Opus 5. Paid Claude users get higher usage limits. For people building apps, Anthropic says it costs about 40% less on typical work.

GPT-6 Sol and Luna

OpenAI built Sol for complex coding and Luna for smaller tasks. Luna costs less for people building apps. Both are rolling out in Codex, OpenAI's coding app, and ChatGPT Work. They are not in regular ChatGPT chat yet.

Why this matters

Claude users can test Opus 5.5 on a task that used to take several tries. Codex users can start with Luna for a small change and use Sol for work across several files. If you use neither, you can wait. Release claims alone are not a reason to change apps.

ℹ️ Know first: The speed and cost figures are company claims. Lower prices for app builders do not change chat subscription prices.
