MiMo-V2.5 vs Qwen3.8-Flash-Next

Xiaomi · China  |  Alibaba · China · Updated June 2026

Quick verdict

Pick MiMo-V2.5 for native omnimodal — strong image and video understanding or very low cost (~half the inference of the pro tier). Pick Qwen3.8-Flash-Next for swe-bench pro (62.5, ahead of claude opus 4.6 max's 53.4) or cost efficiency: ~1/9th the training cost of qwen3.7-plus, ~12x cheaper api than flagship qwen3.8-max. On a tight budget at scale, MiMo-V2.5 is the value pick.

MiMo-V2.5 (Xiaomi) and Qwen3.8-Flash-Next (Alibaba) are two of the models people most often weigh against each other in 2026. MiMo-V2.5 is xiaomi's cheap omnimodal model — Pro-level agentic perception across image and video at a fraction of the cost. Qwen3.8-Flash-Next is alibaba's open-weight preview of its next-generation Qwen4 hybrid-attention architecture, released August 26, 2026 as a 125B-parameter (6B active) MoE model priced roughly 12x below its own flagship Qwen3.8-Max. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

Native omnimodal — strong image and video understanding

MiMo-V2.5

Xiaomi's cheap omnimodal model — Pro-level agentic perception across image and video at a fraction of the cost — and it runs cheaper at $0.14/$0.28 per 1M tokens.

Very low cost (~half the inference of the Pro tier)

MiMo-V2.5

At $0.14/$0.28 per 1M tokens it undercuts Qwen3.8-Flash-Next ($0.16/$0.47 per 1M tokens), and that gap compounds at volume.

Agent-framework integration

MiMo-V2.5

Xiaomi's cheap omnimodal model — Pro-level agentic perception across image and video at a fraction of the cost — and it carries the larger 1M context.

SWE-bench Pro (62.5, ahead of Claude Opus 4.6 Max's 53.4)

Qwen3.8-Flash-Next

Alibaba's open-weight preview of its next-generation Qwen4 hybrid-attention architecture, released August 26, 2026 as a 125B-parameter (6B active) MoE model priced roughly 12x below its own flagship Qwen3.8-Max — and it is the newer of the two.

Cost efficiency: ~1/9th the training cost of Qwen3.7-Plus, ~12x cheaper API than flagship Qwen3.8-Max

Qwen3.8-Flash-Next

Qwen3.8-Flash-Next lists cost efficiency: ~1/9th the training cost of Qwen3.7-Plus, ~12x cheaper API than flagship Qwen3.8-Max among its strengths; MiMo-V2.5 does not.

Vision-based agentic tasks (AndroidWorld: 84.5)

Qwen3.8-Flash-Next

Qwen3.8-Flash-Next lists vision-based agentic tasks (AndroidWorld: 84.5) among its strengths; MiMo-V2.5 does not.

Lowest cost at scale

MiMo-V2.5

At $0.14/$0.28 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

MiMo-V2.5

Its 1M window is about 3.8× larger than Qwen3.8-Flash-Next's 262K tokens natively (extensible to 1M with YaRN), fitting roughly 1,500 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

MiMo-V2.5

At $0.14/$0.28 per 1M tokens it undercuts Qwen3.8-Flash-Next, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

MiMo-V2.5

Larger 1M window fits more in one prompt.

Anyone whose priority is native omnimodal — strong image and video understanding

MiMo-V2.5

It is specifically built for that.

Anyone whose priority is swe-bench pro (62.5, ahead of claude opus 4.6 max's 53.4)

Qwen3.8-Flash-Next

That is its strongest area.

MiMo-V2.5: where it fits

Xiaomi's cheap omnimodal model — Pro-level agentic perception across image and video at a fraction of the cost. Released April 22, 2026 by Xiaomi, it is built for native omnimodal — strong image and video understanding, very low cost (~half the inference of the Pro tier), agent-framework integration, and 1M context for full documents in one pass.

Its trade-offs are real: not the deepest reasoning tier (see V2.5-Pro), and limited Western tooling and support. At $0.14 in / $0.28 out per million tokens, it sits in the budget price band.

Qwen3.8-Flash-Next: where it fits

Alibaba's open-weight preview of its next-generation Qwen4 hybrid-attention architecture, released August 26, 2026 as a 125B-parameter (6B active) MoE model priced roughly 12x below its own flagship Qwen3.8-Max. Released August 26, 2026 by Alibaba, it is built for sWE-bench Pro (62.5, ahead of Claude Opus 4.6 Max's 53.4), cost efficiency: ~1/9th the training cost of Qwen3.7-Plus, ~12x cheaper API than flagship Qwen3.8-Max, vision-based agentic tasks (AndroidWorld: 84.5), and previews Qwen4's hybrid gated-DeltaNet plus sparse-attention architecture.

Its trade-offs: trails Claude Opus 4.6 Max on Humanity's Last Exam (35.9 vs 40.0), lower OSWorld 2.0 binary success rate (19.4%), and an open-weight architecture preview rather than Alibaba's polished flagship product. At $0.16 in / $0.47 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

MiMo-V2.5 and Qwen3.8-Flash-Next overlap enough that the right pick depends on your specific job. MiMo-V2.5 costs less per token; MiMo-V2.5 holds the larger context; and each leads in its own area — MiMo-V2.5 for native omnimodal — strong image and video understanding, Qwen3.8-Flash-Next for swe-bench pro (62.5, ahead of claude opus 4.6 max's 53.4). Rather than crowning one, run the same hard task through both once and let the results decide.

Public SWE-Bench figures are not available for either model, so the honest test is your own repository — run an identical real bug through both. By design, MiMo-V2.5 leans toward native omnimodal — strong image and video understanding while Qwen3.8-Flash-Next leans toward swe-bench pro (62.5, ahead of claude opus 4.6 max's 53.4), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, MiMo-V2.5 or Qwen3.8-Flash-Next?

MiMo-V2.5 is cheaper — $0.14/$0.28 per 1M tokens vs $0.16/$0.47 per 1M tokens, roughly 1.1× apart on input.
