    The nerfing/quantization strategy is unsustainable. The first lab to not do it wins (short term). The Anthropic pause on Fable might just have been that.

    My gut tells me this involves an undisclosed, never-released grandparent model (higher-class than Fable/Astra level, roughly unsellable due to unfeasible cost). That grandparent model is distilled into lower models, of which Opus 5.5 might be an instance of.

    That also guarantees protection against distilling a core business. You never make your prime weights available to the public, you only make distillings themselves available.

    The downside of this strategy is that you spend a lot of compute on something that you never release, but it might be just the right play (for now) for closed weight companies.

    It's a gut feeling, I have zero hard evidence to back it up (it's what I would do as them).
