- The post highlights a massive increase in consumed thinking tokens during coding-style reasoning.
- It claims Kimi K3 uses about 10× more thinking tokens for coding than any other model observed.
- The model is also said to have effectively memorized Unsplash image IDs, enabling stronger image reasoning without a web search tool call.
- The attached visual shows a very long thinking trace broken into steps like planning, choosing images, deciding page sections, animation design, CSS design, header design, checkout design, and micro-interaction design.
- The result reportedly helps generate websites with higher relevance and accuracy on DesignArena than previously seen.
