We need to write a professional original news article, 300-500 words, SEO optimized, human-like, no AI style, clear structure, with analysis. Title: Fidji Simo Bids Farewell to OpenAI; Brockman Leads Product. Summary given but we don't need to include summary? The instruction says Title and Summary given; we should output only the SEO-optimized content (the article). Likely we need to include title at top? It says "Title:" then title; "Summary:" then summary. Probably we need to include title and maybe a meta description? But they said "Return only the SEO-optimized content." Usually that includes title and body. We'll output title then article sections with headings.

We must ensure 300-500 words. Let's target ~380 words.

We need SEO optimized: include keywords like Fidji Simo, OpenAI, Greg Brockman, product leadership, AI industry, etc. Use natural language.

Structure: Introduction, Key Developments, Industry Analysis, Future Outlook, Conclusion.

We'll write paragraphs with headings maybe using HTML? Not required. Just plain text with headings.

Make sure no AI style: avoid phrases like "In today's fast-paced world". Write like a human journalist.

Let's craft ~380 words.

Check word count.

We'll draft:

Title line: Fidji Simo Bids Farewell to OpenAI; Brockman Leads Product

Then maybe a short lead paragraph (introduction). Then sections.

Let's write ~380 words.

Count manually approximate.

I'll write then count.
