Interfaze Beta vs Qwen3.5 397B

Pick Interfaze Beta if you want the stronger benchmark profile. Qwen3.5 397B only becomes the better choice if multimodal & grounded is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Interfaze Beta is clearly ahead on the provisional aggregate, 76 to 64. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Interfaze Beta's sharpest advantage is in knowledge, where it averages 89.9 against 65.2. The single biggest benchmark swing on the page is MMMU-Pro, 71.1% to 79%. Qwen3.5 397B does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.

Qwen3.5 397B is also the more expensive model on tokens at $0.60 input / $3.60 output per 1M tokens, versus $1.50 input / $3.50 output per 1M tokens for Interfaze Beta. Interfaze Beta is the reasoning model in the pair, while Qwen3.5 397B is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Interfaze Beta gives you the larger context window at 1M, compared with 128K for Qwen3.5 397B.
