我主要用国产 AI。请用一张表帮我对号入座：每一行是「任务场景 → 推荐模型 → 一句话理由」，覆盖这些场景：写代码/数学推理、读长文档/做文献综述、日常问答和语音聊天、电商文案和多模态识图、数据分析和做图表。

I mainly use China-made AI. Give me a table that matches jobs to tools: each row is "Scenario → Recommended model → One-line reason", covering: coding / math reasoning, reading long documents / literature review, everyday Q&A and voice chat, e-commerce copy and multimodal image understanding, and data analysis / charting. Prefer free or strong-experience options (DeepSeek, Kimi, Doubao, Tongyi Qianwen, Zhipu Qingyan), and after the table add one line reminding me there is no single "best" model, only the most suitable one.
