He noted OpenAI’s blog showing a 2× per‑month increase in Codex spending by researchers, but said this does not constitute strong evidence of an imminent self‑sustaining intelligence explosion. Denain expressed uncertainty about how quickly internal metrics at labs might signal a feedback loop, and he highlighted that the public evidence of rapid acceleration remains limited.\n\nThe conversation turned to robotics, where both participants agreed that large‑scale industrial automation may be far off the two‑to‑five‑year horizon, citing reliability and regulatory challenges. Regarding Chinese models, Denain estimated the public release gap between Chinese labs and OpenAI/Anthropic to be roughly six to eight months, while acknowledging measurement noise and possible over‑fitting in benchmark indices. He contrasted this with other views that place the gap at two to four months for specific models such as Kimi K3 and GLM 5.2.","keyPoints":["Epoch AI’s JS Denain estimates Chinese public model releases lag US labs by about six to eight months","He cites a 2×‑per‑month rise in Codex spending by researchers but says it isn’t solid proof of imminent AI self‑sustaining acceleration","Both agree robotics may see industrial gains, but likely over a longer horizon than two‑to‑five years"],"whyItMatters":"Understanding the US‑China model gap and acceleration signals helps investors, policymakers, and labs gauge competitive dynamics and risk timelines.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Epoch AI","OpenAI","Anthropic","Amazon"],"models":["Kimi K3","GLM 5.2","Claude"],"people":["Jean‑Stanislas \"JS\" Denain","Nathan Lambert","Evan Hubinger","Florian"]},"firstPublishedAt":"2026-09-22T13:37:45Z","updatedAt":"2026-09-22T13:37:45Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Interconnects","title":"Debating RSI, the US-China Gap, and Jaggedness with JS Denain of Epoch AI","url":"https://interconnects.ai/p/debating-rsi-the-us-china-gap-and","publishedAt":"2026-09-22T13:37:45Z","type":"newsletter","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"JS Denain of Epoch AI says Chinese models lag US labs by about six to eight months\", 22 September 2026, https://digestai.news/story/js-denain-of-epoch-ai-says-chinese-models-lag-us-labs-by-about-six-to","publisher":"Digest AI","title":"JS Denain of Epoch AI says Chinese models lag US labs by about six to eight months","datePublished":"2026-09-22T13:37:45Z","url":"https://digestai.news/story/js-denain-of-epoch-ai-says-chinese-models-lag-us-labs-by-about-six-to"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
