Got some fun if slightly janky looking pelicans out of this one: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

I ran it on all seven reasoning levels supported by OpenRouter, but the reasoning token counts suggest to me that it doesn't actually support seven different levels. This is one of my biggest problems with OpenRouter - their abstraction layer makes reasoning levels harder to reason about.

  reasoning_level  reasoning_tokens

  none             0
  minimal          6,520
  low              11,873
  medium           5,678
  high             9,779
  xhigh            10,197
  max              13,386

Update: explained here: https://api-docs.deepseek.com/guides/thinking_mode/

That says it supports three levels - low, high, max, and maps them out like this:

  minimal   low
  low       low
  medium    high
  high      high
  xhigh     high
  max       max
  ultra     max

(But it looks like "none" is a valid option too.)
