Qwen 4 Might Be Coming. Is the Open vs. Closed Gap Actually Closing?
Qwen 4 hype is back, and so is the question of whether open weights can finally catch Opus 5.5. Spoiler: the real gap might not be the model at all, but the GPU rack you’d need to run it.
The Skim: Open-weight AI fans are hyped for Qwen 4, and the replies are split between "finally" and "slow down." Nothing about it is confirmed yet.
The Hook
It's Sunday night and the AI timeline is doing what it does best: arguing about a model that hasn't shipped. The question on everyone's mind is whether Qwen 4 can close the gap with Opus 5.5.
The Meat
The hype: Spotted on X, one fan said they'd care more about a Qwen 4 drop with open weights than GPT-6.2. Another post claimed 27B variants land first, that early samples are nearing Astra/Opus 5.5 quality, and that Alibaba is leaning on recursive self-improvement across the Max, Plus, Flash, and 27B lineup. Those are leaks and rumors, not announcements. Treat them accordingly.
The reality check: The skeptics showed up fast. As one user put it, an Opus 5.5 level model is "close to impossible," and even if it happens, it'll be the Max version most of us can't run. Another pointed out that the teaser says nothing about weights at all.
The real bottleneck: A few replies made the sharper point, which is that the gap for most teams isn't the leaderboard score.
- The Hardware Problem: If a model needs a multi-GPU node, most people will use it through a hosted API anyway. At that point, price per token decides.
- The Trust Problem: One commenter noted the real gap is whether anyone on your team can tell when the output is wrong, open or closed.
- The Data Problem: Another asked whether it's silly to worry about sending data to a Chinese-hosted model when you can't run it locally. Not silly. It's a fair question about where your data goes, and running locally is the main way around it.
Meanwhile, the Open-Weights Favorites
- DeepSeek V4.1 Flash: One fan called it the Opus 5.5 of open weights. Another countered that it's nowhere near Sol or Opus 5.5, and that its real perks are low cost and local running.
- GLM 5.3: Fans say it hallucinates less and feels more stable, with one admitting DeepSeek "sometimes feels like it wants to cheat you."
- The Business Model Question: Someone asked how Qwen makes its money back by giving models away. No one answered.
The Takeaway
Don't hold your breath for Opus 5.5 level from Qwen 4, but a strong 27B you can run locally would still be a big win. Wait for the actual release notes before picking a side.
