MiniMax's video-and-agent model against Qwen's faster, cheaper all-rounder.
MiniMax M3 and Qwen3.8 Flash are both million-token multimodal models built for coding and long agent jobs. MiniMax is the larger, privacy-oriented option; Qwen is the cheaper one that is available right now.
MiniMax M3 has 427B parameters, reads pictures and video, supports tools, offers zero retention and costs $1.20 per million tokens. It is currently paused while capacity is added. Qwen3.8 Flash costs $0.47, matches the million-token window and modalities, but does not list ZDR.

Where MiniMax M3 pulls ahead
- Zero data retention, which Qwen3.8 Flash does not offer — relevant for sensitive video or agent work.
- A larger model (427B parameters) aimed at long agent tasks and video.
- A good fit when a workflow needs both tools and visual input under retention guarantees.
Where Qwen3.8 Flash pulls ahead
- Availability: Qwen3.8 Flash is ready to chat now, while MiniMax M3 is paused for capacity.
- Price: $0.47 versus $1.20 per million tokens, about 2.5x cheaper.
- A fast multimodal all-rounder for everyday image, video and coding questions without waiting for capacity.
The price difference
MiniMax M3 costs $1.20 per million tokens against $0.47 for Qwen3.8 Flash — about 2.6x more. On UsingOpen you can chat with both for free inside the daily limit, so the rate is a fair proxy for how expensive each model is to run rather than a bill you pay here. Multiply it by your monthly token volume if you are comparing API access elsewhere.
Which should you choose?
For most people today, Qwen3.8 Flash is the practical pick: it is available, cheaper and handles the same text, image and video work. The missing ZDR is the trade-off to weigh.
MiniMax M3 is worth waiting for when zero retention and a larger multimodal agent model matter more than price and immediate availability. Check the live status on the chat page; paused models return when capacity does.
