Sept 8, 11 AM PT. Save your seat Model performance Optimizing delta weight syncs for managed rollouts How Baseten runs managed RL rollouts for frontier open-weights models cross independent rollout clusters in under 40 seconds. Authors Paras Stefanopoulos Last updated September 8, 2026 Share TL;DR Baseten supports delta weight syncs to leading frontier models like GLM-5.3 across global, independent clusters in under 40 seconds , with only 6 seconds of request pause. AI labs and frontier research teams use our managed rollouts offering to run their frontier-scale RL. They control the trainer and we run the rollouts on the same infrastructure that powers inference for Cursor, Hubspot, Lovable, and Notion. A trainer runs in the customer's environment. It publishes full checkpoints and small deltas to object storage. A Baseten deployment leveraging a global pool of capacity watches the same stream, reconstructs the requested policy, updates GPUs across our fleet, and keeps serving. We use the Baseten Delivery Network for the large object transfers so each cluster only downloads..."},"evidence_pages":[],"related_signals":[{"id":"7b42fac2-f048-41b3-9275-349c47f2335a","url":"https://onlylabs.fyi/signals/7b42fac2-f048-41b3-9275-349c47f2335a","source_url":"https://www.baseten.co/blog/how-baseten-makes-pyannotes-diarization-models-96x-faster/","title":"How Baseten Makes Pyannotes Diarization Models 96x Faster","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-09T00:00:00+00:00","first_seen_at":"2026-09-09T20:00:53.077479+00:00","date_source":"sitemap.lastmod"},{"id":"4bc6b810-0677-4409-a1bb-b8d733ecb37b","url":"https://onlylabs.fyi/signals/4bc6b810-0677-4409-a1bb-b8d733ecb37b","source_url":"https://www.baseten.co/blog/baseten-leads-covals-voice-ai-benchmark/","title":"Baseten Leads Covals Voice Ai Benchmark","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-08T22:20:40+00:00","first_seen_at":"2026-09-09T00:00:51.730848+00:00","date_source":"sitemap.lastmod"},{"id":"3af4f3d3-59a4-4686-94ba-6b6cacdd1091","url":"https://onlylabs.fyi/signals/3af4f3d3-59a4-4686-94ba-6b6cacdd1091","source_url":"https://www.baseten.co/blog/new-mcp-and-skill-for-coding-agents-to-use-baseten/","title":"New Mcp And Skill For Coding Agents To Use Baseten","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-02T18:20:19+00:00","first_seen_at":"2026-09-02T20:00:52.042916+00:00","date_source":"sitemap.lastmod"},{"id":"8dd84285-f6fb-49cb-a423-7039fcdde208","url":"https://onlylabs.fyi/signals/8dd84285-f6fb-49cb-a423-7039fcdde208","source_url":"https://www.baseten.co/blog/best-open-source-models-for-post-training/","title":"Best Open Source Models For Post Training","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-02T10:51:41+00:00","first_seen_at":"2026-09-02T12:01:45.497094+00:00","date_source":"sitemap.lastmod"},{"id":"9848b185-9578-4f96-8911-a25dba91ec70","url":"https://onlylabs.fyi/signals/9848b185-9578-4f96-8911-a25dba91ec70","source_url":"https://www.baseten.co/blog/the-efficient-frontier-of-llm-inference/","title":"The Efficient Frontier Of Llm Inference","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-01T23:47:31+00:00","first_seen_at":"2026-09-02T00:00:51.666285+00:00","date_source":"sitemap.lastmod"},{"id":"54f6a3fb-74e2-45ec-98c7-ee266104b764","url":"https://onlylabs.fyi/signals/54f6a3fb-74e2-45ec-98c7-ee266104b764","source_url":"https://www.baseten.co/resources/changelog/viewer-role-for-read-only-access/","title":"Viewer Role For Read Only Access","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-01T20:18:10+00:00","first_seen_at":"2026-09-02T00:00:51.666285+00:00","date_source":"sitemap.lastmod"}]}
