To be honest, whether large language models reach the level of Fable 5 is not especially meaningful to most people doing actual work. It is not going to leave everyone dizzy and collapsing into their chairs as though they had just witnessed an atomic bomb detonation. Whether you can make use of Fable 5-level capabilities depends, in practice, on how you code.
There are many degrees of agentic coding.
First, there are the fundamentalist Vibe coders. These people unwaveringly follow the Andrej Karpathy path and remain committed to using AI throughout the entire programming process. At this point, they have essentially undergone mechanical ascension. The code they produce can be compared to humanity in the Warhammer 40K universe relative to real-world humans—in simple terms, they are no longer human.
Generally speaking, this group has an extremely high ceiling and an equally low floor.
Reaching the ceiling requires becoming the god of prompt engineering while simultaneously using harness prompts to condition the AI into a sex slave. The floor consists of people who cannot articulate what they want at all. The archetypal example is the client who asks for “colorful black,” after which the system produces nothing but indescribable, Cthulhu-like creatures.
