I went down a rabbit hole this morning reading the late-2025 Juejin AI tool roundups side by side — the 12-scenario 2025 年度盘点 piece, the December authoritative eight-mainstream coding ranking, the November frontend-developer picking guide, and the July global LLM leaderboard — and the thing that finally crystallized for me is that the 2025 roundup format made a quiet structural shift that nobody called out, the broad-market roundups and the category-specific roundups stopped sharing a common price-anchor frame, and the engineer doing the actual selection is left multiplying per-scenario subscriptions in their head to discover the cumulative monthly bill that neither format is willing to print. I want to put it down before the price-anchor split hardens into a permanent format split.

The piece that pushed me over the edge was the December coding ranking that printed Tencent CodeBuddy at 9.6 out of 10, Sourcegraph Cody at 8.2, Replit Ghostwriter at 8.0, Codeium at 7.8, Tabnine at 7.6, Amazon CodeWhisperer at 7.5, JetBrains AI Assistant at 7.4, and Blackbox at 7.2 on a five-axis card nobody else seems to use, alongside the 2025 年度盘点 piece that priced Gemini Pro and ChatGPT Plus and Claude Pro all at 140 元 per month with no attempt to combine them. To be fair the December ranking was explicit about being coding-only, and I am taking the exact decimal scores with a grain of salt because the test corpus is undisclosed, but the structural disconnect is what has been rattling around in my head all morning. The coding post ranks eight tools and never mentions price, the broad-market post prices five flagship tools and never asks which two you would actually combine.
