Compared to OpenRouter prices", "summary": "Apple's upcoming M5 Ultra, with 512GB memory and 1.2TB/s bandwidth, is projected to cost $15,000–17,000 when it ships in October, making local AI inference for models like DeepSeek V4 Pro, Kimi K3, and GLM-5.3 potentially cost-effective versus OpenRouter API pricing, with payback periods ranging from 16 to 60 months depending on the model.", "body_md": "New Studio M5 Ultra ready for local home AI lab? I compared it to OpenRouter prices.\n512GB will be available from October, and I guess that the price will be around 15-17k.\nLet's see how much it will cost to run a proper openweight model at home:\nDeepSeek V4 Pro: 2 Macs, $32–34k\nKimi K3 and GLM-5.3: 4 Macs, $64–69k\nAt 100 output tokens/sec, 24/7, compared with OpenRouter prices today, the hardware payback would be:\nKimi K3: 16–18 months\nDeepSeek V4 Pro: 36–39 months\nGLM-5.3: 56–60 months\nK3 makes sense for a privacy first fully local setup.\n\nThe 512GB M5 Ultra will ship in October with a massive 1.2TB/s memory bandwidth.\n50% more memory bandwidth than M3 Ultra, 4.4x more than DGX Spark and M4 Pro.\nStacking 4 x M5 Ultra, I expect you'll be able to run Kimi K3 / GLM 5.3 faster than the API (>100 tok/sec).", "url": "https://wpnews.pro/news/new-studio-m5-ultra-ready-for-local-home-ai-lab-compared-to-openrouter-prices", "canonical_source": "https://twitter.com/gherget/status/2092293494446420010", "published_at": "2026-08-28 07:31:46+00:00", "updated_at": "2026-08-28 07:48:15.426936+00:00", "lang": "en", "topics": ["ai-infrastructure", "artificial-intelligence"], "entities": ["Apple", "M5 Ultra", "DeepSeek V4 Pro", "Kimi K3", "GLM-5.3", "OpenRouter", "DGX Spark", "M4 Pro"], "alternates": {"html": "https://wpnews.pro/news/new-studio-m5-ultra-ready-for-local-home-ai-lab-compared-to-openrouter-prices", "markdown": "https://wpnews.pro/news/new-studio-m5-ultra-ready-for-local-home-ai-lab-compared-to-openrouter-prices.md", "text": "https://wpnews.pro/news/new-studio-m5-ultra-ready-for-local-home-ai-lab-compared-to-openrouter-prices.txt", "jsonld": "https://wpnews.pro/news/new-studio-m5-ultra-ready-for-local-home-ai-lab-compared-to-openrouter-prices.jsonld"}}
