# Five New AI Models Compared: Why Qwen 3.8 Is the Only One Worth Your Time

Five new AI models hit the field this week, and only one of them is probably worth your time. Let's take a look.

Contender 1: Muse Glimmer. This is Meta's newest open weights model, a 30 billion parameter dense model. It's fast, it's cheap, and it's slightly smarter than Claude Haiku. If you have nice hardware (like a fully loaded MacBook Pro), you can run this at no cost. I've been testing it and it's not bad but not as good as Qwen3.6.

Contender 2: NVIDIA Nemotron 3.5 Lightning. A 30 billion parameter model intended for light agent use. Its main draw is speed and low memory requirements. Out of the box, this model is not particularly bright, but it's meant to be fine tuned (on NVIDIA hardware, of course)

Contender 3: Grok 4.6. xAI's latest model, that offers intelligence comparable to GPT-5.6-sol, under Claude's fifth generation models, and powered by Elon Musk's complete lack of ethics. While capable, I would not use xAI for anything, partly because of data privacy issues and partly because in terms of sustainability, xAI is the WORST of the worst among AI companies.

Contender 4: DeepSeek V4 Pro 0813. This is DeepSeek's latest model after the shocking DeepSeek V4 Flash 0731 from a couple weeks ago. Pro is smarter than its previous iteration, somewhere between GPT-5.6-luna and terra and on par more or less with Claude Sonnet 5.

Contender 5: Alibaba Qwen 3.8. This is Qwen's latest model, open weights, state of the art, offering Fable 5 capabilities at what will likely be a fraction of the cost, possibly 1/10th the cost. It's a beast - you genuinely need a data center to run it. But for companies who worry about losing access to Fable-class models, this would - with a hefty investment in hardware, like half a million bucks to start - give you unlimited access to state of the art AI.

Artificial Analysis has a very nice grid that makes the case for each model in terms of intelligence (vertical axis, nearer to the top is better) and cost (horizontal axis, nearer to the left is better). These new entrants don't offer a ton - DeepSeek Pro is smarter, but not by much, than its Flash sibling. Glimmer and Lightning are situationally useful locally, and there's no reason to use Grok, period. Qwen has not been evaluated yet at time of writing for pricing on independent providers; from Alibaba itself, it's dirt cheap.

The big question will be where Qwen3.8 27B (releasing on 2026-08-15) will land - it might be fast enough, smart enough, and cheap enough to displace DeepSeek, NVIDIA, and Muse.

No matter how you slice it, the fact that 4 out of 5 models on this list are open weights models is amazing, models you can download and run on your own hardware if you have enough of it, and that's good for everyone.
