**Refining the Structure** \n\n I've finalized the headers and structure, confirming that the character counts for H2 and H3 tags are within the target range. Now, I'm concentrating on content drafting, focusing on expanding the descriptions of the model's capabilities, including the "Thinking" process, its safety features, and the advantages of GPT Proto's platform, such as the unified dashboard and single API key. I'll need to remember to implicitly reference the API Doc URL through the parameters. The table's been drafted, and I'll add extra content to ensure I hit the word count. Finally, I've checked all links to ensure they're accurate.
