Read more AI models DeepSeek-V4.1-Flash: more efficient prefill for coding agents Discover DeepSeek-V4.1-Flash, a 552B multimodal MoE model featuring a Causal Encoder-Decoder architecture and efficient KV caching. Authors Albert Lee Kenzie Amack Marylise Tauzia Last updated September 11, 2026 Share TL;DR DeepSeek released V4.1-Flash this week: a 552B-parameter multimodal MoE model with a Causal Encoder-Decoder architecture built for coding agents. It's available now as a Baseten Model API, with improved KV cache efficiency and asymmetric prefill/decode compute over its V4 predecessors. This week, DeepSeek released the open weights for DeepSeek-V4.1-Flash on HuggingFace , and the model is already available on Baseten Model APIs (with Loops support coming soon). Key specifications include: 552B total parameters 8B active parameters for prefill, 16B for decode 1M token context window Multimodal input (text + image), text output Originally popularized by Google's Gemini series, the \"flash\" designation describes lighter, less expensive models designed to perform similarly to larger ones...."},"evidence_pages":[],"related_signals":[{"id":"b4405912-fcfd-4298-9411-e3d0f0f31f58","url":"https://onlylabs.fyi/signals/b4405912-fcfd-4298-9411-e3d0f0f31f58","source_url":"https://www.baseten.co/resources/changelog/oidc-and-aws-assumerole-for-training-jobs/","title":"Oidc And Aws Assumerole For Training Jobs","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-11T21:53:45+00:00","first_seen_at":"2026-09-12T00:00:51.377491+00:00","date_source":"sitemap.lastmod"},{"id":"28ce6173-bc5f-4857-8a4f-578670f7c128","url":"https://onlylabs.fyi/signals/28ce6173-bc5f-4857-8a4f-578670f7c128","source_url":"https://www.baseten.co/resources/changelog/model-api-costs/","title":"Model Api Costs","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-11T16:07:15+00:00","first_seen_at":"2026-09-11T20:00:56.216273+00:00","date_source":"sitemap.lastmod"},{"id":"7192f26f-bd48-4fff-8e34-24b47f55a231","url":"https://onlylabs.fyi/signals/7192f26f-bd48-4fff-8e34-24b47f55a231","source_url":"https://www.baseten.co/resources/changelog/deepseek-v41-flash-available-on-baseten/","title":"Deepseek V41 Flash Available On Baseten","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-10T22:08:32+00:00","first_seen_at":"2026-09-11T00:00:53.401936+00:00","date_source":"sitemap.lastmod"},{"id":"d98b464d-c3eb-4c9d-94a1-50a3abeb0a93","url":"https://onlylabs.fyi/signals/d98b464d-c3eb-4c9d-94a1-50a3abeb0a93","source_url":"https://www.baseten.co/resources/changelog/regional-deployments/","title":"Regional Deployments","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-10T18:56:54+00:00","first_seen_at":"2026-09-10T20:00:53.149963+00:00","date_source":"sitemap.lastmod"},{"id":"493c5874-3900-4fd2-814d-e88c624b2128","url":"https://onlylabs.fyi/signals/493c5874-3900-4fd2-814d-e88c624b2128","source_url":"https://www.baseten.co/blog/blaxel-is-joining-baseten-to-build-the-future-of-agentic-cloud/","title":"Blaxel Is Joining Baseten To Build The Future Of Agentic Cloud","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"baseten","name":"Baseten","category":"neocloud"},"occurred_at":"2026-09-10T16:07:53+00:00","first_seen_at":"2026-09-10T20:00:53.149963+00:00","date_source":"sitemap.lastmod"},{"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"}]}
