§ Verdict

Which one should you use?

Choose DeepSeek V4-Pro if…

you can run most traffic off-peak, your work is text-only, and a mid-tier model passes your evals.

Choose Qwen3.8-Max if…

you want a flagship-tier model with the same price at any hour, or a 1M-token free quota to evaluate on Alibaba Cloud's international region.

Blended rate decides it

DeepSeek doubles V4-Pro's rates from 01:00–04:00 and 06:00–10:00 UTC on weekdays. If a large share of your traffic lands in that window — European mornings, for example — calculate a blended rate. Even at peak, V4-Pro stays cheaper than Qwen3.8-Max's $2.00/$6.00 on standard rates, and the same holds for cached input: V4-Pro's peak cache hit is double its off-peak $0.022, still well under Qwen's $0.17.

Qwen's pricing is simpler

Alibaba lists qwen3.8-max as a single price tier from 0 to 1M input tokens, billing all tokens in a request at that rate, with the same price for thinking and non-thinking modes. That predictability is worth something for customer-facing products where you can't control when users arrive.

Capabilities and limits

DeepSeek lists V4-Pro as text-only, thinking-by-default, with up to 384K output tokens and a 500-request concurrency limit. Check Alibaba's console for Qwen3.8-Max limits in your region before sizing a launch.
