Model details

MiniMax M3 (MiniMax)

MiniMax M3 is a multimodal model designed for complex coding and agent-driven work. Its sparse-attention Mixture-of-Experts architecture has 428 billion total parameters, with 23 billion active, and is reported to support context windows of up to one million tokens. It accepts images and video and includes computer-use capability, making it suited to repository analysis, debugging, testing, and multi-step tasks that extend beyond a single text exchange.

The model is positioned as a unified open-weight option for reasoning and practical software tasks. MiniMax’s reported SWE-Bench Pro result of 59.0% provides a useful indicator of coding performance, while the sparse-attention design is associated with faster long-context responses of up to 15.6 times. This combination makes M3 particularly relevant for applications that require broad context, visual inputs, tool use, and sustained task execution.

Official sourceAnnouncement

LLM Gateway's own blog post on OpenCode Go pricing confirms that MiniMax M3 is part of the active model catalog on the platform, grouped alongside MiniMax M2.7, Kimi K2.7, Qwen3.7 Max, GLM-5.2 and others in the $60-per-month allocation tier. The post explains that the $10/month Go plan now meters usage by dollar at eac Because metering runs at per-token rates, the article stresses that how far the $60 ceiling stretches depends entirely on which model is picked, framing M3 alongside higher-cost entries like Grok 4.5 and GPT-5.6 Luna. It also notes that past a limit, requests fall back to free models (currently Ox Alpha Free, marked li

CoverageLeaks

The Towards AI piece dated June 4, 2026 frames MiniMax M3's release inside a broader news roundup alongside OpenAI Codex expansion and Microsoft's MAI-Thinking-1. It reports that MiniMax positioned M3 with "frontier coding and agentic scores" and a 1-million-token context window, and treats the release as one that mate The article's emphasis is on which releases change the daily loop for builders, which benchmarks are actually being compared, and which cost structure makes agentic work more usable. In that framing, M3 is grouped with reasoning-style releases aimed at long-context agentic coding workflows, with its 1M context claim ci
