DeepSeek V4 Flash

Versions:DeepSeek V4 Flash (0731)DeepSeek V4 FlashDeepSeek V4 Flash (Latest)

DeepSeek-V4-Flash, released April 2026, is a lightweight 284-billion-parameter sparse MoE with just 13 billion active parameters per token, supporting a one-million-token context window. It reaches roughly 10% of the inference FLOPs and 7% of the KV-cache memory of V3.2, using a hybrid of Compressed Sparse Attention (CSA) and Heavily Compressed Attention (HCA) for efficient long context. The model offers three reasoning modes, non-think, think-high, and think-max, plus a dedicated XML-based tool-call format that preserves reasoning content across tool-call boundaries for cleaner agentic loops. Its reasoning quality is reported to approach the larger V4-Pro on many tasks. Open-sourced under an MIT license with weights on Hugging Face, V4-Flash targets cost-conscious teams deploying long-context reasoning agents that need affordable million-token inference.

Uptime and availability

One of DeepSeek V4 Flash's 8 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.

100%route uptime, last 30 days

Its other routes aren't measured here yet.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 7 further routes are not on the board yet. See uptime for every provider Opper monitors.
