I was a subscriber of their now-unavailable coding plan. The 1000 TPS was very unique at the time, but nowadays their qwen 3.8 gets roflstomped by Mercury 3 at both cost and performance at similar TPS speed. There's not much reason to use them unless you're an enterprise with a custom deal.
Qwen3.8 27B is a dense model with expensive K/V caching. It's fantastic if you have 32-48GB of VRAM and want to run 1 or 2 agent sessions locally. But if serving batch inference for many users, it's expensive.
DeepSeek V4 Flash 0731 is dirt cheap at scale, less than 10% of the cost of Qwen3.8 27B. This is because it's an MoE and it uses much less VRAM for KV cache. And it's generally a better model. V4.1 is also cheap at scale, though I've heard mixed reports on the optimized K/V caching.
You should not be running Qwen3.8 27B on an API normally. Maybe Cerberas's hardware is bad at batching or supporting more efficient K/V caching schemes, or something like that?
If you have 48GB of VRAM, you should be able to get Qwen3.8-Flash-Next running and from my use, it's basically the tipping point. 27B is great for a bit of work, but I have QFN running non stop (when I can gather the correct ideas for it to implement).
