	personal remarks (so far)
Claude	works surprisingly well, almost magically reads your mind
Codex	knows low level stuff, a bit grumpy and likes being baby-sited at times, so far pretends to do stuff
Grok	it is honest, does not waste your time, for light projects with answers from SO
Gemini	out of control hallucinations, a wild horse doing whatever it wants, appears to start well but in reality it just bluffs, no good for burning tokens, use Grok instead then, complains a lot, forgets what we spoke 5 min ago
