Sitemap . Engineering Under the Hood: Serving Kimi K3 By Jonathan Dieu and Shree Murthy Updated: July 30, 2026 12 min read <- Back to blog home DigitalOcean launched Kimi K3 on day 0. It’s already one of the most popular models on the platform and across the market: second most likes on Hugging Face, sixth most traffic on OpenCode. Getting a model this size running well on day zero took real work across several teams. Thanks to Moonshot AI, Inferact, RadixArk, NVIDIA, and AMD for the help getting there. Standing up a new model, integrating it into DigitalOcean’s Inference Engine, and showcasing its unique attributes on day 0 takes three things: the right hardware, a tuned serving stack, and rigorous verification against Moonshot’s own benchmarks. Here are the lessons we learned along the way: Hardware selection and implementation We selected NVIDIA HGX™ B300 and AMD Instinct™ MI350x GPUs to run K3 because these instances provide the memory capacity, FLOPs, and interconnect horsepower necessary for a model of K3’s size and architecture. We built our distributed inference stack with llm-d because it includes..."},"evidence_pages":[],"related_signals":[{"id":"e661bace-d012-462c-a8a3-5bde0fbac484","url":"https://onlylabs.fyi/signals/e661bace-d012-462c-a8a3-5bde0fbac484","source_url":"https://www.digitalocean.com/blog/introducing-v5-droplets","title":"Introducing v5 Droplets: next-generation performance, sized to your workload","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-08-26T02:19:47.496+00:00","first_seen_at":"2026-08-26T04:00:49.088377+00:00","date_source":"rss.item_date"},{"id":"91b005cc-6cea-4626-b2dc-e6d1aa6eba17","url":"https://onlylabs.fyi/signals/91b005cc-6cea-4626-b2dc-e6d1aa6eba17","source_url":"https://www.digitalocean.com/blog/managed-agents-runtime-services-private-preview","title":"Private Preview: DigitalOcean Managed Agents Runtime Services","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-08-25T19:01:05.321+00:00","first_seen_at":"2026-08-25T20:01:48.028096+00:00","date_source":"rss.item_date"},{"id":"1611dd9e-0552-44a9-97ce-dbcf7165472f","url":"https://onlylabs.fyi/signals/1611dd9e-0552-44a9-97ce-dbcf7165472f","source_url":"https://www.digitalocean.com/blog/patching-januscape-amd-safe-ret","title":"Patching at Fleet Scale, Twice: How DigitalOcean Closed Januscape and the AMD Safe RET Issue Without Customer Impact","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-08-24T21:25:19.02+00:00","first_seen_at":"2026-08-25T00:00:48.900041+00:00","date_source":"rss.item_date"},{"id":"80ddd34a-a6aa-4861-a037-79e938b8846d","url":"https://onlylabs.fyi/signals/80ddd34a-a6aa-4861-a037-79e938b8846d","source_url":"https://www.digitalocean.com/blog/inference-router-cache-aware","title":"DigitalOcean Inference Router, Now Cache-Aware: Why the Cheapest Model Isn't Always the Best Deal","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-08-20T21:20:20.321+00:00","first_seen_at":"2026-08-21T00:00:48.944988+00:00","date_source":"rss.item_date"},{"id":"3ee6766b-f174-4068-9d67-0491eb4c995c","url":"https://onlylabs.fyi/signals/3ee6766b-f174-4068-9d67-0491eb4c995c","source_url":"https://www.digitalocean.com/blog/model-synthesis","title":"Outperforming Fable 5 at half the price: meet model synthesis, a new server-side tool on DigitalOcean Inference Engine","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-07-23T20:03:12.073+00:00","first_seen_at":"2026-07-24T00:00:49.579749+00:00","date_source":"rss.item_date"},{"id":"9736d4f5-49b8-4ce7-95b8-22de9c9b43b5","url":"https://onlylabs.fyi/signals/9736d4f5-49b8-4ce7-95b8-22de9c9b43b5","source_url":"https://www.digitalocean.com/blog/price-changes-gpus","title":"Upcoming GPU Pricing Updates","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"digitalocean","name":"DigitalOcean (GradientAI)","category":"neocloud"},"occurred_at":"2026-07-21T00:30:53.697+00:00","first_seen_at":"2026-07-21T04:01:48.837755+00:00","date_source":"rss.item_date"}]}
