We have seen no noticable improvements (at usable prices) for 7 months, when the original Sonnet 3.5 came out.
Maybe specialized hardware for LLM inference will improve so rapidly that o1 (full) will be quick and cheap enough a year from now, but it seems extremely unlikely. For the end user, the top models hadn't gotten cheaper for kore than a year until the release of Deepseek v3 a few weeks ago. Even that is currently very slow at non-Deepseek providers, and who knows just how subsidized the pricing and speed at Deepseek itself is, given political interests.
