Do not give a high rating to summaries, paraphrases, explanations of technical terms, or generic observations such as "this will be worth watching" or "the timeline remains uncertain" if they could easily be produced by a general-purpose generative AI, even if they are well written. Use the following five-level rating scale. * **S — Advanced Original Expert Analysis**: Integrates multiple sources, comparisons, industry knowledge, or other information to provide important insights, evaluations, or a broader picture that would be difficult to obtain simply by reading the original sources individually * **A — Subject-Specific Expert Analysis**: Contains clear comparisons, reasoning, verification, or evaluation specific to the company, technology, or announcement being discussed * **B — Mainly Expert Explanation**: Provides specialist explanation or organization of the topic, but contains limited original analysis specific to the subject * **C — Organization and Summary of Primary Information**: Primarily summarizes primary information, but provides some added value through human editing, organization, or supplementary explanation * **D — AI-Level Summary and Formatting**: Offers little beyond the summarization and formatting of primary information that could be produced by a general-purpose generative AI, with almost no original analysis or informational value **Original reporting, proprietary data, original calculations, or the discovery of new facts are not required for an S rating.** An article may qualify for S if it compares and integrates multiple publicly available sources to provide important insights or a broader picture that readers could not easily obtain by reading those sources individually. However, do not give an S rating merely because the article contains a large amount of information, covers many subjects, or uses extensive technical terminology. In particular, consider the following points. * Does the article contain information or perspectives that would be difficult to obtain simply by reading the original announcement? * Does it contain comparisons, reasoning, verification, or evaluation specific to the subject? * Does it integrate multiple pieces of information to provide a new understanding or broader picture? * Could the content easily be produced by a general-purpose generative AI? * Are you avoiding giving a high rating merely because the article uses technical terminology or headings such as "Analysis" or "Key Points"? In your response, first briefly show the **S–D rating scale above**, and then clearly indicate **where this article falls within that scale**. Then briefly explain the following. * **Rating for this article: S / A / B / C / D** * **Reason for the rating** * **Specific passages that qualify as original analysis** If you are uncertain between two ratings, choose the lower one rather than the higher one.
