The company reports 3.8 times PhysX's simulation performance. For teams building robot-learning systems, faster simulation could lower the cost of generating training experience, but the public announcement leaves the comparison conditions unresolved.","published_at":"2026-11-09","updated_at":"2026-11-09","record_date":"2026-11-09","date_kind":"published_at","topics":["open-source","compute"],"entities":["Skild AI","NVIDIA","Steel","Newton","PhysX"],"related_patterns":["generative-media-becomes-application-infrastructure"],"novelty_label":"new_fact","what_changed":"Skild AI and NVIDIA introduced Steel, an open-source GPU rigid-body dynamics solver for Newton, reporting simulation performance 3.8× PhysX's.","prior_refs":["https://newruntime.com/posts/standard-physics-launches-archimedes-and-open-sources-reynolds-18540b/","https://newruntime.com/posts/standard-physics-launches-archimedes-design-agents-and-open-c9c761/"],"source_url":"https://skild.ai/blogs","source_urls":["https://skild.ai/blogs"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:skild-ai-and-nvidia-open-source-steel-a-046417","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/skild-ai-and-nvidia-open-source-steel-a-046417/","markdown":"https://newruntime.com/posts/skild-ai-and-nvidia-open-source-steel-a-046417.md","json":"https://newruntime.com/posts/skild-ai-and-nvidia-open-source-steel-a-046417.json"},"markdown_url":"https://newruntime.com/posts/skild-ai-and-nvidia-open-source-steel-a-046417.md","next_reads":[{"type":"topic","path":"/topics/open-source/","url":"https://newruntime.com/topics/open-source/","title":"Open Source","reason":"Explore the open-source topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/open-source.md","json_url":"https://newruntime.com/topics/open-source.json"},{"type":"topic","path":"/topics/compute/","url":"https://newruntime.com/topics/compute/","title":"Compute","reason":"Explore the compute topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/compute.md","json_url":"https://newruntime.com/topics/compute.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
