• Introducing the smallest model in our new architecture family, with native visual understanding.
• Designed for greater capability, faster inference, higher throughput, and scaling to larger models. (View Highlight)
Smaller KV cache. Bigger savings.
Compared with the previous generation, V4.1-Flash’s KV cache needs just:
• 1/4 the HBM
• 1/8 the SSD storage
Cache-hit charges often account for a large share of agent costs. Compressing the cache cuts those costs significantly. (View Highlight)
V4.1-Flash is now live on the DeepSeek API with native multimodal support.
Set your model to deepseek-flash.
• V4-Flash & V4-Flash-Vision-Exp are retired. For compatibility, deepseek-v4-flash and deepseek-v4-flash-vision-exp temporarily route to V4.1-Flash.
• Tests by multiple parties put V4.1-Flash ahead of V4-Pro on performance, cost, speed & total runtime. We’re phasing out V4-Pro.
• Starting at 04:00 UTC on Sept 14, 2026, all deepseek-v4-pro requests will route to V4.1-Flash at V4.1-Flash rates. This will continue until V4.1-Pro launches.
Official partners WorkBuddy (including CodeBuddy) & OpenCode now fully support V4.1-Flash. Try it today! (View Highlight)
More efficient architecture. Lower API prices.
V4.1-Flash lets us serve more users at a lower cost. We’re passing the savings on to you.
• Peak/off-peak pricing continues to balance demand.
• Off-peak rates are 50% of peak rates. Schedule flexible workloads off-peak to save.
• New pricing takes effect at 04:00 UTC on Sept 10, 2026. (View Highlight)
