The headline is accurate. What MiniMax doesn’t put in the headline: a 93% hallucination rate on independent reliability testing. Before you start migrating agentic pipelines, you need both numbers. What MiniMax Is Claiming On AutomationBench-AA — a benchmark for complex enterprise agent workflows — M3.1 Flash tops all comers, leaving Claude Opus 5 at 50.3 and GPT-5.6 Sol at 45.8 behind. It scores 73.7% on DeepSWE v1.1 (software engineering), 82% on CyberGym […]\n\nThe post", "url": "https://wpnews.pro/news/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost", "canonical_source": "https://byteiota.com/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost/", "published_at": "2026-10-19 22:08:08+00:00", "updated_at": "2026-10-19 22:15:42.227114+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-agents", "ai-products"], "entities": ["MiniMax", "M3.1 Flash", "Claude Opus 5", "GPT-5.6 Sol", "AutomationBench-AA", "DeepSWE v1.1", "CyberGym"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost", "markdown": "https://wpnews.pro/news/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost.md", "text": "https://wpnews.pro/news/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost.txt", "jsonld": "https://wpnews.pro/news/minimax-m3-1-flash-tops-agent-benchmarks-hides-the-cost.jsonld"}}
