Today marks the end of Fable 5's subscription plan， presumably for an extended period.
While Anthropic has made it clear they intend to keep Fable in the subscription plan in the future， they haven't specified a date.
GPT-5.6 Sol is a good alternative for now， although there are certainly significant differences. But as I've mentioned several times， the rates with 5.6 are enormous， so its use remains somewhat limited at present.
In any case， 5.6 was a major release that undoubtedly gave OpenAI a significant boost compared to Anthropic. Now the question is how Anthropic will handle this. My guess：
They will release Opus 5 very soon as a cheaper alternative to Fable 5， hoping that this will appease the public. Sonnet 5 is hardly worth mentioning after its release， and I haven't used it myself. Therefore， I don't believe we'll see Fable 5 back in the plan anytime soon， but I'm happy to be proven wrong. （P.S.： @thsottiaux ， please reset the rates 👉👈）
