DeepSeek V4.1 Flash vs Qwen 3.6 Plus

Kyma serves all of these, so the availability, throughput and latency below are its own readings rather than anybody's marketing. What each creator publishes about its own model is further down, kept separate, and clearly theirs.

No winner here. DeepSeek V4.1 Flash, Qwen 3.6 Plus sit inside the band, so this measurement cannot separate them. The honest claim is that they are all up between 99.9 and 100.0%.

The tinted band is the measurement's own grain. It is 0.3 points wide, which is what three failed requests are worth in the thinnest sample on this page. One or two is what luck looks like, so a lead has to clear all three before this page will call it. Scale starts at 99%, not at zero, and dot size is the size of the sample behind the figure.

Anything inside the band is level with the leader as far as this measurement can tell. Anything left of it is genuinely behind.

Throughput

Median tokens per second, from one identical prompt sent to every model every six hours, so the only variable left between two rows is the model.

Longer is better.

Latency

Median time to a complete response on that same fixed prompt. It moves with output length, so it is a reading on one prompt rather than a promise about yours.

What this instrument does not measure

This page carries no benchmark scores, so it will not tell you which model is smarter. It tells you which is cheaper, which is faster, which stays up, and what each one accepts. For the quality question, run both on your own prompts: one key, one line changed, and the answer is about your work rather than someone else's test set.

Every model above runs on one key and one balance. $0.50 of free-tier credit on signup, no card.Get API key
