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.

Availability, and how much of it we can actually see
Successful observations divided by total observations over the last 30 days, counting Kyma's own probe and real customer requests the same way. Same method and same figures as /models.
Only one of these models has been measured for long enough to publish, so there is nothing to compare yet.
DeepSeek V4.1 FlashQwen 3.6 PlusThe tinted band is the measurement's own grain. It is 0.2 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 58%, not at zero, and dot size is the size of the sample behind the figure.
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.
DeepSeek V4.1 FlashQwen 3.6 PlusLatency
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.
DeepSeek V4.1 FlashQwen 3.6 PlusAt least one model here has been measured for days rather than months. Its figures are real readings, not estimates, but they rest on a sample thin enough that a single failure would move them by a full point or more, which is why this page will not rank on them.

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.
