MegaDev AI Workshop: researchers03? Wait. We must follow: The input is "Primary source headline: MegaDev AI Workshop". We should produce a rewritten headline in factual, neutral single-sentence style, sentence case, company/product names as given. But there is no other content. We should avoid extra speculation. The headline could be "MegaDev AI Workshop". But need to avoid generic meta-framing and keep exact names. It says if original title is already clear, prefer light edit. So the rewritten headline should be "MegaDev AI workshop" with capitalization rule: sentence case only first word capitalized and proper nouns. "MegaDev AI Workshop" has "AI" as acronym; proper noun? It's a product/company? It's a workshop name. In sentence case, would be "MegaDev AI workshop" (AI is acronym; should be capitalized). They say capitalize only the first word and proper nouns (company/product/model names). AI might be considered an acronym; is it a proper noun? It is an acronym for Artificial Intelligence; typically capitalized as "AI". In sentence case, you would preserve "AI". So "MegaDev AI workshop" or "MegaDev AI Workshop"? The rule: capitalize ONLY the first word and proper nouns (company/product/model names). "AI" is not a proper noun; it's an acronym but often treated as proper. They say preserve proper nouns. Not sure. They gave example: "OpenAI launches new model" - they capitalized OpenAI and not launches. They didn't show AI usage. For "AI" as acronym, it's considered a proper noun? Might be considered a proper noun. But if "AI" is an acronym inside the name, it's probably part of the title "MegaDev AI Workshop". I'd keep as "MegaDev AI workshop" with lowercase "workshop" since not a proper noun. But the instruction: sentence case: capitalize ONLY the first word and proper nouns (company/product/model names). If "AI" is considered a proper noun, it's within the middle; the rule would require capitalizing it since it's a proper noun. So "MegaDev AI Workshop" maybe. Hmm: "first word" is "MegaDev" capitalized already; proper nouns in the rest: "AI" is an acronym; likely considered a proper noun. So keep as "MegaDev AI Workshop". That matches original capitalization except "Primary source headline" but we should output just the rewritten headline. The original "MegaDev AI Workshop" maybe already well-formed; we should provide light edit: "MegaDev AI Workshop". So output: MegaDev AI Workshop But instruction says no quotes, just text. So: MegaDev AI Workshop MegaDev AI Workshop

Original headline: "MegaDev AI Workshop"
