DeepSeek launches V4.1-Flash with 1M-token context and 4x smaller KV-cache
matlabulous · x · 2026-09-11
DeepSeek officially introduced DeepSeek-V4.1-Flash, the smallest model in its new architecture family, now live on the FLock API platform.
- Built for agentic and long-context workloads with a 1M-token context window
- Native text and image understanding, plus adjustable reasoning effort
- New architecture cuts global KV-cache footprint to roughly 890 bytes per token, 4x smaller than DeepSeek-V4-Flash
- Positioned for greater capability, faster inference, and higher throughput, scaling toward larger models
Target use cases include coding agents, document analysis, visual reasoning, and complex automation.
