I use fable 5.1 (tried opus but it lied to me 3 times in quick succession and ignored me in another)

This is weird to ask because I feel like of course the model isn't omniscient? Isn't the whole point of iterating on a plan to assess impact, risk, know your (the user) variables, user impact, product impact, etc for making a change? I cannot count the times even in the past few months where I start a conversation with my C suite because their desired outcome would have a potential negative impact elsewhere for other products or users.

Is this just not something that comes up at Anthropic?
