Gemini

Conclusion first: this is not another “type a topic → force it into a template → output garbage” AI PPT tool. It runs a complete expert workflow — requirement research, material retrieval, outline planning, layout planning, visual design — where every step allows manual fine-tuning, or the whole thing can run automatically end to end. In terms of output, pages generated with Gemini 3 Flash already reach commercial delivery quality.

We often see URLs like these: 1 2 3 /v1/chat/completions /v1/messages /v1/responses These suffixes are not decoration — they define a complete request and response data structure. Pick the wrong one and your code either errors out or silently loses data. This article starts at /v1/completions and works its way to /v1/responses, explaining what each suffix stands for, why it was designed that way, and where the common pitfalls are.
