Hunyuan 4 vs MiMo V2.6 Pro: A Light-Use Receipt

2026-10-25 Model price-offs EN

01 / The basket: 1,000 small requests, not an agent marathon

For light workloads, start with the receipt rather than a leaderboard. Suppose you need short email drafts, ticket classifications or compact document summaries. Our illustrative basket contains 1,000 requests, each using 1,000 input tokens and 200 output tokens: one million input tokens and 200,000 output tokens altogether. These are budgeting assumptions, not measured model usage or benchmark results.

We compare Hunyuan 4 and MiMo V2.6 Pro using published provider rates in Chinese yuan, keeping both sides in the same currency without introducing an exchange-rate assumption. These are reference calculations, not CheapRelay quotes. Actual relay charges must use the rates displayed for your selected route.

02 / The rate cards behind each line item

For Hunyuan 4, this calculation uses Tencent's preview offering: CNY 6 per million uncached input tokens, CNY 18 per million output tokens and CNY 0.30 per million cached input tokens. Confirm the underlying endpoint before treating a catalog label as an exact match. ([cloud.tencent.com](https://cloud.tencent.com/document/product/1823/130055?utm_source=openai))

MiMo V2.6 Pro lists CNY 3 per million uncached input tokens, CNY 6 per million output tokens and CNY 0.025 per million cache-hit input tokens. These are its published CNY rates, not converted dollar prices. ([mimo.mi.com](https://mimo.mi.com/models/en-US/mimo-v2.6-pro))

03 / Receipt one: short answers without cache hits

■ Hunyuan 4 input: 1,000,000 / 1,000,000 × CNY 6 = CNY 6.00.
■ Hunyuan 4 output: 200,000 / 1,000,000 × CNY 18 = CNY 3.60.
■ Hunyuan 4 basket total: CNY 9.60, or CNY 0.0096 per request.
■ MiMo V2.6 Pro input: 1,000,000 / 1,000,000 × CNY 3 = CNY 3.00.
■ MiMo V2.6 Pro output: 200,000 / 1,000,000 × CNY 6 = CNY 1.20.
■ MiMo V2.6 Pro basket total: CNY 4.20, or CNY 0.0042 per request.

The calculated difference is CNY 5.40 per 1,000 requests. MiMo V2.6 Pro costs 56.25% less for this particular token basket at these reference rates. That is an arithmetic comparison, not a promotional discount or evidence of equal answer quality. ([cloud.tencent.com](https://cloud.tencent.com/document/product/1823/130055?utm_source=openai))

04 / Receipt two: longer answers change the checkout total

Keep input unchanged but increase each answer from 200 to 500 tokens. Hunyuan 4 now costs CNY 6.00 for input plus CNY 9.00 for output: CNY 15.00. MiMo V2.6 Pro costs CNY 3.00 plus CNY 3.00: CNY 6.00. The gap becomes CNY 9.00. A concise response specification is therefore worth testing before optimizing an already-small input bill. ([cloud.tencent.com](https://cloud.tencent.com/document/product/1823/130055?utm_source=openai))

05 / Receipt three: an 80% cache-hit scenario

Return to 200-token answers. Assume usage records show 800,000 cached input tokens and 200,000 uncached input tokens. Hunyuan 4 totals CNY 0.24 cached input + CNY 1.20 fresh input + CNY 3.60 output = CNY 5.04. MiMo V2.6 Pro totals CNY 0.02 + CNY 0.60 + CNY 1.20 = CNY 1.82. These calculations assume the stated hits actually occur and exclude any separately billed cache writes. ([cloud.tencent.com](https://cloud.tencent.com/document/product/1823/130055?utm_source=openai))

Do not budget an 80% hit rate merely because prompts share instructions. Treat it as a scenario until billing records confirm it. Keep cache reads, cache writes, fresh input and output as separate receipt lines.

06 / Choose by accepted answers, then check the relay receipt

My cost-first starting point would be MiMo V2.6 Pro, followed by a small comparison on your actual tasks. That is not a quality verdict. Record accepted answers, retries, billable tokens and corrections. Divide total spend by accepted results; a cheap rejected answer is not a finished task.

CheapRelay offers pay-as-you-go access with no monthly fee or subscription, billing real tokens, including cache reads and writes. Its OpenAI-compatible routes let you keep an existing SDK workflow while comparing the two models. Sign up for CheapRelay, run a small matched sample, and replace these reference receipts with your actual route charges before scaling.
