> The highest quality tools in the software development space tend to be FOSS

LLMs are also software and OSS (let alone FOSS ones) aren't even close to the quality of closed models like GPT 5.2 or Opus 4.5.

LLMs are more money thrown at their training than software development, and you need prohibitive costly hardware to run the biggest ones.

Calling some "OSS" is simply misleading.
