true, but it's also super easy to switch models via Bedrock (my harness switches subagents between A\, OAI, Kimi, Grok, etc... GLM 5.3 is locked behind some dumb request system which I personally believe is because Amazon is heavily invested in A\) and you're not locked in with the Claude Enterprise features (i swear to god if someone sends another claude artifact instead of publishing to git...)
