- Grok 4
Even if those were almost free to run, you'd be way better off with Deepseek flash 0731 or GPT 5.6 Luna, which already are almost free.
Other than for things where the t/s are critical, it seems like a bad idea to etch a model into silicon.
Bad perspective: consider the correction: "when are thresholds of sought quality reached"? Hence: not "is there a 10yo from last year that could compete with the current 13yo", but "will there be a 30(?)yo from last year that could compete with the current 33(?)yo" ('(?)': the scale of yearly growth in the future is uncertain).
A 10 year old iPhone is probably good enough, but is there demand for it? In a vacuum a 10 year old iPhone is good, but why would you pick it if you can have a current one for a reasonable price?
So, when the models will be "good enough", you will probably use one as the "daily driver" for a long time for consolidated workflows (some of them enabled by the staggering collateral advantages of specialized hardware and obvious advantages of local hardware), and occasionally use other available models for exceptional tasks, and upgrade only when definitely advantageous - like normal goods.
