MiniMax M3 API: bilingual flagship with 1M-token context

MiniMax M3 is the lab's latest flagship model, combining strong bilingual Chinese-English reasoning with a one-million-token context window at a low price.

On YepAPI you call MiniMax M3 through a single OpenAI-compatible endpoint at $0.42 per 1M input and $1.68 per 1M output tokens, with a 1,048,576-token context window.

What is MiniMax M3?

MiniMax M3 is the newest flagship from MiniMax, a Chinese AI lab known for strong bilingual models. M3 leads its lineup on reasoning and generation while carrying a 1,048,576-token context window and up to 32,768 output tokens, so it can take in very large inputs and reason across them. Its defining strength is balanced Chinese and English performance: it is trained to reason and write fluently in both, which makes it a strong pick for cross-language and China-market applications where models trained mainly on English data tend to weaken. The combination of flagship quality, huge context, and low price makes it a high-value option.

Build with MiniMax M3 via YepAPI

Access MiniMax M3 through YepAPI's OpenAI-compatible /v1/ai/chat endpoint. Point your OpenAI SDK at YepAPI and set the model string to minimax-m3; moving to another model later is a one-string change. A single YepAPI key also reaches every other model plus SEO, SERP, and web-scraping tools, so you can scrape and rank content in Chinese or English, then have M3 summarize or generate from it within one integration and one bill.

MiniMax M3 API pricing — $0.42 / $1.68 per 1M tokens

MiniMax M3 costs $0.42 per 1M input tokens and $1.68 per 1M output tokens on YepAPI. For a flagship model with a million-token window and genuine bilingual strength, that is aggressive pricing. It lets you run large-context bilingual workloads continuously without flagship-tier costs, and because your key spans every model, you can mix M3 with cheaper options for routine sub-tasks.

MiniMax M3 for bilingual and China-market applications

M3 is the right choice when Chinese-language quality matters as much as English: building assistants for bilingual audiences, localizing and adapting content for the China market, translating with cultural nuance, and reasoning over mixed-language document sets. The million-token context lets it handle large bilingual corpora in one pass, and its flagship reasoning keeps quality high across both languages where single-language models degrade.
