TokenHubでDeepSeek V4.1 Flashを利用する際の一般的な質問です。
DeepSeekのマルチモーダルMoEモデルで、552Bパラメータのバックボーン、非対称Causal Encoder–Decoder構造、テキストと画像の入力対応を備えます。
コーディングエージェント、長文脈分析、視覚文書の理解、大きな入力を繰り返し扱う高スループット処理に適しています。
効率的な非対称計算、大幅に小さい永続KVキャッシュ、100万トークンのコンテキスト、ネイティブ画像理解、エージェント処理への対応が強みです。
オープンウェイトは非常に大きく自前運用には多くの資源が必要です。画像入力に対する出力は画像ではなくテキストで、重要な結果は検証が必要です。実際の処理で品質・遅延・総コストを確認してください。

It’s officially out and the prices have been updated. /// Today, we officially release the DeepSeek-V4.1-Flash model. It is the smallest model in our new architecture family, with native multimodal visual understanding. The new architecture is designed for a higher capability ceiling, faster inference, higher throughput, and scaling to larger models. GPQA Diamond: 90.9 HLE: 36.8 (39.1*) Codeforces (Rating): 3471 MathArena Apex: 65.6 Terminal-Bench 2.1: 90.6 Terminal-Bench 3.0: 30.0 Terminal-Bench 4.0: 31.2 DeepSWE v1.1: 74.2 ProgramBench: 20.3 NL2Repo-Bench: 65.4 CyberGym: 88.1 SEC-Bench Pro: 62.8 ExploitGym: 15.3 HLE (w/tools): 63.9 Automation-Bench: 54.8 Agents' Last Exam: 31.8 Chartography (w/tools): 78.9 BabyVision (w/tools): 89.6 ZeroBench-main (w/tools): 49.0 * Tested only on the pure-text subset of the HLE benchmark set. API changes DeepSeek V4.1 Flash is now available on the DeepSeek API with native multimodal support. Change the model name to deepseek-flash to call the latest V4.1 Flash model. The previous-generation models V4 Flash and V4 Flash Vision Exp have been retired; for compatibility, the model names deepseek-v4-flash and deepseek-v4-flash-vision-exp are temporarily routed to V4.1 Flash. Meanwhile, extensive testing shows that V4.1 Flash now outperforms DeepSeek V4 Pro across performance, cost, speed, and total time, so we plan to retire V4 Pro in an orderly manner. After 12:00 Beijing Time on September 14, 2026, and until the future release of V4.1 Pro, all requests to deepseek-v4-pro will be routed to V4.1 Flash and billed at the V4.1 Flash price. API apricing adjustment With the release of DeepSeek-V4.1-Flash, API prices have been reduced accordingly. For details, please refer to Models & Pricing. /// Source: https://api-docs.deepseek.com/updates/#deepseek-v41-flash-release
DeepSeek V4.1 Flash: Stronger, Faster, More Accessible

Original Source from DeepSeek WeChat Official Account: https://mp.weixin.qq.com/s/qg0NU3NNUbp1co2PdkAPAg Today we're officially releasing the DeepSeek V4.1 Flash model. It is the smallest model in our brand-new model architecture series, with native multimodal visual understanding. The new architecture was designed with these goals in mind: a higher capability ceiling, faster inference, greater throughput, and scalability to larger-parameter models. Asymmetric architecture: big intelligence at low cost DeepSeek V4.1 Flash is a 552B-parameter MoE model built on a brand-new Causal-Encoder-Decoder architecture. Input and output are asymmetric: only 8B parameters are activated on the input side and 16B on the output side, making it significantly cheaper than known models of the same size. V4.1 Flash also uses a new pre-training approach and has gone through larger-scale reinforcement learning post-training. In benchmark testing, it surpasses the intelligence level of a range of flagship models, including DeepSeek V4 Pro. r/LocalLLaMA - DeepSeek V4.1 Flash: Stronger, Faster, More Accessible (https://preview.redd.it/deepseek-v4-1-flash-stronger-faster-more-accessible-v0-qq5p9q5qymoh1.png?width=1080&format=png&auto=webp&s=3ae8cc6dbdd62a2b2ec7f59dc207d147c9165c0f) r/LocalLLaMA - DeepSeek V4.1 Flash: Stronger, Faster, More Accessible (https://preview.redd.it/deepseek-v4-1-flash-stronger-faster-more-accessible-v0-2tvpysuvymoh1.png?width=1080&format=png&auto=webp&s=84ed35f530b3c0a4534036eaa4fc83cfce641b7d) Less cache, lower cost The new generation of models dramatically reduces the size of the KV cache. Compared with the previous generation, HBM requirements drop to 1/4 and SSD requirements to 1/8. In agent scenarios, cache-hit charges often make up a large share of the bill, so compressing the KV cache substantially lowers the cost of agent-style tasks. r/LocalLLaMA - Figure: DeepSeek's continued progress in reducing context storage. Relative to the first-generation model, the KV cache has shrunk 437×.

Relative to the first-generation model, the KV cache has shrunk 437×. API support DeepSeek V4.1 Flash is now live on the DeepSeek API with native multimodal support. Simply change the model name to deepseek-flash to call the latest V4.1 Flash. The older V4 Flash and V4 Flash Vision Exp models have been retired; for compatibility, the model names deepseek-v4-flash and deepseek-v4-flash-vision-exp will temporarily be routed to V4.1 Flash. In addition, extensive testing shows that V4.1 Flash comprehensively outperforms V4 Pro on performance, cost, speed, and total time-to-completion, so we plan to phase out the V4 Pro model in an orderly fashion. After 12:00 Beijing time on September 14, 2026, and until V4.1 Pro launches, all requests to deepseek-v4-pro will be routed to V4.1 Flash and billed at V4.1 Flash's unit price. Tencent (WorkBuddy, CodeBuddy) and OpenCode, as official partners, have now fully integrated DeepSeek V4.1 Flash — give it a try! API pricing adjustment Thanks to the architectural innovations, DeepSeek V4.1 Flash can serve more users at lower cost, so we have cut V4.1 Flash's pricing accordingly. To allocate resources more sensibly, we continue to use peak/off-peak pricing, with off-peak prices at half the peak rate, and encourage users to schedule tasks around their actual usage patterns. The new prices take effect at 12:00 on September 10, 2026. r/LocalLLaMA - DeepSeek V4.1 Flash: Stronger, Faster, More Accessible (https://preview.redd.it/deepseek-v4-1-flash-stronger-faster-more-accessible-v0-qkhui0kjzmoh1.png?width=1690&format=png&auto=webp&s=0d6ce254d63e29bfabea7c65638342717a5d1e54) Open-source release We will fully support the open-source community in adapting inference for the new model, and will explore various ways to broaden deployment. If you have large-scale deployment needs and the corresponding resources (a 2k-GPU cluster with storage cluster), please get in touch.
