Описание модели

Deepseek deepseek-v4-flash

DeepSeek-V4-Flash is DeepSeek's cost-efficient open-source model, released on April 24, 2026. It is a 284B parameter Mixture-of-Experts (MoE) language model with only 13B active parameters, pre-trained on 32T tokens, supporting a context length of one million tokens. V4-Flash delivers reasoning performance approaching V4-Pro while being significantly faster and cheaper — making it ideal for high-volume, latency-sensitive workloads.

Why It Looks Great

Mixture-of-Experts architecture with 284B total parameters and only 13B active — the smallest activation among Tier-1 models
1000000 context window powered by Compressed Sparse Attention (CSA) and DeepSeek Sparse Attention (DSA)
Near V4-Pro reasoning performance at a fraction of the cost

Key Features

Context Window: 1000000 tokens
Max Output: 384000 tokens
Vision: Not Supported
Function Calling: Supported
Thinking Mode: Supported (non-thinking / high / max)
JSON Output: Supported
FIM Completion: Supported (non-thinking mode only)

DeepSeek V4 Flash API

deepseek/deepseek-v4-flash

DeepSeek V4 Flash is DeepSeek's efficiency-first open-source model released in April 2026, built on a 284B-parameter Mixture-of-Experts architecture with just 13B parameters active per token — the smallest activation footprint among current Tier-1 models. It shares the same 1M-token context window and hybrid attention design as V4 Pro, delivering near-equivalent reasoning capability (LiveCodeBench 91.6, Codeforces 3052, SWE-bench Verified 79.0) while running significantly faster and at dramatically lower cost. Pre-trained on 32T tokens, V4 Flash is purpose-built for high-throughput, latency-sensitive scenarios such as coding assistants, conversational agents, and batch processing pipelines. It supports thinking and non-thinking modes, function calling, JSON output, and FIM completion.

Часто задаваемые вопросы о DeepSeek V4 Flash

Сколько стоит DeepSeek V4 Flash через API?+

Цены на WaveSpeedAI: $0.17 за миллион входных токенов и $0.34 за миллион выходных токенов. Prompt caching и batch processing тарифицируются отдельно и снижают эффективную стоимость длинных повторяющихся нагрузок.

Каково контекстное окно DeepSeek V4 Flash?+

DeepSeek V4 Flash поддерживает до 1049K токенов контекста и до 384K токенов вывода на запрос.

Совместим ли DeepSeek V4 Flash с OpenAI?+

Да. WaveSpeedAI предоставляет DeepSeek V4 Flash через OpenAI-совместимый endpoint по адресу https://llm.wavespeed.ai/v1. Направьте официальный OpenAI SDK на этот base URL с ключом API WaveSpeedAI — других изменений в коде не требуется.
