Read the report Products Data and storage Infrastructure control Runtime acceleration Model and agent development Mission control Solutions Pricing Resources About us Contact us Login Contact us Login Clear Training a foundation model is, from the east-west fabric&#x27;s point of view, a well-behaved problem. Thousands of GPUs run the same collective at roughly the same time, over and over, for weeks. It&#x27;s brutal on bandwidth, but it&#x27;s rhythmic. You can design around that rhythm. Agentic AI has a less predictable traffic pattern. An agent breaks a task into steps, calls a retriever, calls a tool, calls another model, sometimes calls another agent, and waits on each hop before it knows what the next one is. That serial path is an agent chain, and its latency is the sum of every hop rather than the worst one. Multiply that across thousands of concurrent chains running alongside training jobs and standard inference on the same fleet, and the traffic stops looking like a batch job...."},"evidence_pages":[],"related_signals":[{"id":"ecd521c7-7c82-440f-8f47-5e2f931ad684","url":"https://onlylabs.fyi/signals/ecd521c7-7c82-440f-8f47-5e2f931ad684","source_url":"https://wf.coreweave.com/blog/video-captioning-at-scale-600-tb-in-95-minutes-with-anyscale-on-coreweave","title":"Video Captioning at scale: 600 TB in 95 minutes with Anyscale on CoreWeave","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-28T14:28:36+00:00","first_seen_at":"2026-08-25T16:01:46.875201+00:00","date_source":"rss.item_date"},{"id":"06c14f13-8e5f-4e76-8deb-1f23bd5ef8c9","url":"https://onlylabs.fyi/signals/06c14f13-8e5f-4e76-8deb-1f23bd5ef8c9","source_url":"https://wf.coreweave.com/blog/get-started-with-kimi-k3-dedicated-inference","title":"Get Started with Kimi K3 on CoreWeave Dedicated Inference","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-26T18:38:37+00:00","first_seen_at":"2026-08-26T16:01:42.255194+00:00","date_source":"rss.item_date"},{"id":"43177e68-2dc9-4a44-b5d5-26afacb3dbd2","url":"https://onlylabs.fyi/signals/43177e68-2dc9-4a44-b5d5-26afacb3dbd2","source_url":"https://wf.coreweave.com/blog/coreweave-closes-the-loop-between-training-and-inference","title":"CoreWeave Closes the Loop Between Training and Inference","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-25T17:47:45+00:00","first_seen_at":"2026-06-05T05:42:59.891773+00:00","date_source":"rss.item_date"},{"id":"70440b66-0147-4468-8feb-03c07cf19185","url":"https://onlylabs.fyi/signals/70440b66-0147-4468-8feb-03c07cf19185","source_url":"https://wf.coreweave.com/blog/coreweave-becomes-one-of-the-first-cloud-providers-to-achieve-nvidia-exemplar-cloud-validation-for-inference-on-nvidia-gb200-nvl72","title":"CoreWeave Becomes One of the First Cloud Providers to Achieve NVIDIA Exemplar Cloud Validation for Inference on NVIDIA GB200 NVL72","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-25T17:47:45+00:00","first_seen_at":"2026-06-05T05:42:59.891773+00:00","date_source":"rss.item_date"},{"id":"7ac2e2a3-7a8f-4848-a3dd-9a8c7ac1b933","url":"https://onlylabs.fyi/signals/7ac2e2a3-7a8f-4848-a3dd-9a8c7ac1b933","source_url":"https://wf.coreweave.com/blog/coreweave-leads-mlperf-endpoints-benchmark-with-deepseek-r1","title":"CoreWeave Leads MLPerf 0.7 Endpoints Benchmark with DeepSeek-R1","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-25T17:47:45+00:00","first_seen_at":"2026-07-28T16:00:50.945477+00:00","date_source":"rss.item_date"},{"id":"71af6b2a-9a2b-4857-bc45-3f7ce90e9477","url":"https://onlylabs.fyi/signals/71af6b2a-9a2b-4857-bc45-3f7ce90e9477","source_url":"https://wf.coreweave.com/blog/what-comes-next-operating-and-evolving-the-production-ai-factory","title":"What Comes Next: Operating and Evolving the Production AI Factory","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"coreweave","name":"CoreWeave","category":"neocloud"},"occurred_at":"2026-08-25T17:47:45+00:00","first_seen_at":"2026-08-12T04:01:42.245434+00:00","date_source":"rss.item_date"}]}
