Add This Week in AI recap for September 15-20, 2026

[Stephen-Kimoi]

Summary

• Adds the This Week in AI recap for Sep 15-20, 2026 at blog/en/this-week-in-ai-2026-09-20.mdx (about 1,040 words).
• Covers Claude leading 26% of Anthropic's AI R&D, OpenAI's six misalignment reports, Gemini's test breach of three companies, the Hacktron/Claude Opus 5 OpenAI account takeover, California's kill-switch executive order, the US-China AI incident notification proposal, Anthropic's revenue run rate, Crusoe's Series F, and Qwen3.8-Omni-Flash.
• Window confirmed as Sep 15-20 (just-completed Mon-Sat), picking up after the merged Sep 8-14 edition.

Checks run

• Humanizer pass applied to the prose (tightened a few overclaims; bold-label bullets, title-case headings and the dated byline kept as series house style).
• publish-check: no placeholders, no banned words, no social brief in the file, frontmatter complete, every stat linked.
• seo-apply: no cluster in the Sep 21 SEO drop matches a news recap. Title cut to 65 characters, description set to 153 characters with the "AI news" keyword. Bridge paragraph and FAQ skipped (news recap).

Before merging

• Cover image not uploaded yet. Frontmatter points at imagedelivery.net/.../this-week-in-ai-2026-09-20/public, which currently returns 404. Marked as draft until the cover is uploaded.
• Bloomberg, OpenAI, Axios and CNN pages could not be opened directly; those claims rest on search summaries plus other outlets that report them. Worth a click-through on the 26% figure, the OpenAI framework and the Bessent proposal.
