alt Hacker News1. They absolutely would, eventually, if open models surpassed Ant & OAI's flagships. Keep in mind "surpassed" encompasses both output quality and cost-saving architecture innovations like DSA, which may not be possible to apply to old models (and may take advantage of new hardware!)
2. "They're only as close..." is not natural law. You really think open weights couldn't catch up to a fixed target if Beijing makes it a priority? And what happens to their valuations if they abandon the goal of building AGI? There is no strategic alternative to constant training for these companies, which is why they're, uh, constantly training.
1. Mainstream users don't care about benchmarks or whether some open weight model has technically surpassed GPT-X on a leaderboard. They care about whther GPT does what they want it to do. Capable Open source models already exist, and that hasn't caused ordinary chatGPT users to abandon chatGPT for them. Hell Anthropic exists, and that didn't cause that either. OpenAI still dwarfs Anthropic in the consumer space. Obviously, sufficiently large differences in capability can eventually matter like when Anthropic blew everyone away in coding at one point, but that's very different from saying OpenAI has to train a frontier model every few months or inference margins go to zero.
2. Nobody said anything about a fixed target. Not sure why you interpreted 'slow down' as 'freeze current models forever'.

The capabilities these companies already have, combined with their growing userbases, revenue and distribution are plausibly enough to sustain trillion dollar businesses already. OpenAI is a company with a billion active users that has started running ads that reached ARR of $1 billion in the first 2 months and Anthropic is a company that hit $11B+ in revenue last quarter after a pretty massive jump.
