Mac Studio M5 Ultra: Local AI Without Cloud

🔥 What happened A MacStories writer spent four days benchmarking the new M5 Ultra Mac Studio with 256 GB RAM against its M3 Ultra predecessor and a gaming PC with an RTX 5090. His verdict: it runs local AI agents so fast he made them his daily default. 💡 Why it matters His 99-day project with 310 documents and an agent team on DeepSeek V4 Flash ran entirely local — for $0 in cloud costs. Always-on background tasks via OpenAI or Anthropic APIs would have been cost-prohibitive. ⚡ Our take Anyone still dismissing local agents as toys missed the moment. Apple's unified memory is quietly becoming the sleeper feature for AI engineers.
