MiniMax M3 pitched as the first open-weight frontier-SWE model with 1M context and computer use.

Per LLM-Stats, it combines frontier-tier software engineering, a 1-million-token context window, and native multimodal computer-use in one model. Sourcing is limited to roundup coverage, so treat the SWE claims as provisional until primary benchmarks land. If they hold, it's a rare open option for long-horizon agentic coding plus GUI automation together. Same caution applies to GLM-5.2's reported Opus 4.8 comparison, which I couldn't independently corroborate.
