MiniMax M2.1
VerifiedMiniMax M2.1 handles massive contexts as a closed-source text LLM.
About MiniMax M2.1
MiniMax M2.1 was developed as a closed-source LLM by the company MiniMax. Its architecture emphasizes a 204800-token context capacity that allows processing of lengthy documents or multi-turn dialogues without truncation. This focus on scale distinguishes it for sustained coherence across extended sequences.
The model is suited for professional workflows involving detailed text analysis and generation. Organizations use it in research summarization, legal document review, and complex instruction following where retaining full context improves output quality. Its text modality keeps all capabilities centered on linguistic precision.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "minimax/minimax-m2.1",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: minimax/minimax-m2.1
