Its benchmark estimates a 53.9-day performance doubling time, while execution became faster and cheaper—useful evidence that physical-AI bottlenecks are increasingly about reliable control systems, not only model reasoning.","published_at":"2026-10-27","updated_at":"2026-10-27","record_date":"2026-10-27","date_kind":"published_at","topics":["harness-engineering","agent-runtime"],"entities":["LessWrong","TAG@CoRL","Chrisleet","Bira","FLUX 3 Action","Pi API"],"related_patterns":["harness-architecture-outlives-model-choice"],"novelty_label":"new_angle","what_changed":"The story frames robot-control progress as a doubling-time trend, adding a rate-of-improvement perspective beyond the prior’s snapshot of real-world evaluation scores.","prior_refs":["memory:0f9f137c-8c1e-8785-aa3d-221b8ab845ef"],"source_url":"https://www.lesswrong.com/posts/ndS9Xn8Qx5PppHJ3Q/the-ability-of-frontier-models-to-control-robots-is-rapidly","source_urls":["https://www.lesswrong.com/posts/ndS9Xn8Qx5PppHJ3Q/the-ability-of-frontier-models-to-control-robots-is-rapidly"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:frontier-models-ability-to-control-robot-arms-is-193384","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/frontier-models-ability-to-control-robot-arms-is-193384/","markdown":"https://newruntime.com/posts/frontier-models-ability-to-control-robot-arms-is-193384.md","json":"https://newruntime.com/posts/frontier-models-ability-to-control-robot-arms-is-193384.json"},"next_reads":[{"type":"topic","path":"/topics/harness-engineering/","url":"https://newruntime.com/topics/harness-engineering/","title":"Harness Engineering","reason":"Explore the harness-engineering topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/harness-engineering.md","json_url":"https://newruntime.com/topics/harness-engineering.json"},{"type":"topic","path":"/topics/agent-runtime/","url":"https://newruntime.com/topics/agent-runtime/","title":"Agent Runtime","reason":"Explore the agent-runtime topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agent-runtime.md","json_url":"https://newruntime.com/topics/agent-runtime.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":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
