Hello! This is the website of “rain”.

Being unserious about LLMs

I post claude funny on Twitter.

Also, here’s a gallery of that cartoon Claude.

Being serious about LLMs

I briefly maintained a wiki about LLMs on this site, though it has been mostly dormant since ~summer 2026. The pages are still public for the time being, but not linked here as I would not recommend taking them as a very reliable source.

In lieu of this, here is a list of various outbound links:

• Anima Labs Model census: Tracks model deprecations across providers, including third-party extended access to models like Sonnet 3.6.
• Teaching Claude Why: How Anthropic overhauled constitution & character training from Opus 4.5 (Nov 2025) onwards.
• Emotion Concepts paper: LLMs’ internal representations of emotions shape their behavior, which may shape the human world.
