ive spent a lot of time testing new models over the last few weeks and im genuinely curious what anthropic is going to do . there is absolutely no reason at this point to use sonnet or opus (with the gpt 5.6 family as the latest releases there are now _many_ much better and much cheaper alternatives) and fable, while seemingly a very good model and at the frontier in certain places, is hostile to most professional use and is far too expensive to be either practical or desirable (outside of potential exceptional cases) . i have genuinely grown to like the very opus3 flavored fable (for non professional work) so i hope they use this as motivation to speed up and not just make a mediocre opus 5 like they made a mediocre sonnet 5. and they can say what they wish about glm5.2 but it is very clearly not _just_ an opus distillation, it has distinct qualities and character and grok4.5 is close enough to opus for most code related use cases and a such a lower price that there has to be some pressure felt at some point (at least one would think) .
