Earlier quoted context omitted.
Stay with 4.6 if you can, it is disabled (afaik) on vscode claude code extension. 4.7 IMO is around 10-20% worse at understanding your prompt intention. You need more effort to explain your intention clearer so it doesn't divert.
Same. 4.7 intelligence is significantly worse than 4.6 on ALL 3P Harnesses. So only on Claude Code and Anthropic API/Subscription you get decent performance but on every other Harness and/or Cloud Provider inference (Bedrock) it performs worse than 4.6 on almost every task. This is not just anecdotal, i've talked to many colleagues from AWS, Microsoft and so on and they all agree that something fishy is going on.
Looking now I see that "Opus 4.6 Legacy" is an option that was not there before, so maybe Anthropic noticed that others are having the same difficulty.
