The weights are available under the MIT license, allowing free commercial use. The model is a Mixture-of-Experts type with 284 billion total parameters, activating only 13 billion during inference, and supports a context length of 1 million tokens. According to benchmark scores, it surpasses the preview version of the higher-tier DeepSeek-V4-Pro, which is more than five times larger, across all nine agent-based benchmark items. Among open models, it also outperformed GLM-5.2 from China in all eight items where scores were published, though it does not reach Anthropic's Claude Opus 4.8 in any item. Community quantized versions are available, including GGUF-format versions from Unsloth in 13 steps ranging from 1-bit at 82.5GB to 8-bit at 162GB. For paid cloud usage, DeepSeek's documentation lists the price at $0.14 per million tokens for input, $0.0028 per million tokens for cached input, and $0.28 per million tokens for output, with prices doubling during peak times.","whyItMatters":"The release came hours after OpenAI cut GPT-5.6 Luna prices by 80 percent, and DeepSeek has now notified users of a significant price increase for the model, suggesting the low-cost strategy drew demand that strained its computing resources.","webCardHtml":"\u003cp\u003e\u003c/p\u003e\u003cul\u003e\n  \u003cli\u003eDeepSeek notified users of the price increase on August 6, 2026, without specifying the new amount, and asked them to plan usage accordingly.\u003c/li\u003e\n  \u003cli\u003eThe price hike follows reports of the model\u0026#39;s inference speed occasionally slowing to extreme levels as demand surged, with DeepSeek\u0026#39;s API status log showing frequent access difficulties around the release.\u003c/li\u003e\n  \u003cli\u003eCEO Liang Wenfeng said in July 2026 that DeepSeek\u0026#39;s computing resources equal about 20,000 NVIDIA H100 GPUs, which some reports say the demand spike has strained.\u003c/li\u003e\n  \u003cli\u003eBloomberg reports DeepSeek is in the middle of a large fundraising round, targeting about $8 billion, with a post-round valuation near $74 billion, and a possible IPO within 2026.\u003c/li\u003e\n  \u003cli\u003eThe fundraising is the second round, resumed on August 6 after trading was temporarily halted in late July following the leak of the CEO\u0026#39;s investor remarks on US-China AI competition.\u003c/li\u003e\n  \u003cli\u003eOpenAI cut GPT-5.6 Luna prices by 80 percent on July 31, bringing input to $0.20 per million tokens and output to $1.20 per million tokens, hours before DeepSeek\u0026#39;s release.\u003c/li\u003e\n  \u003cli\u003eOpenAI said the cut came from extracting further architectural efficiency, though some observers called it a pricing strategy aimed at Chinese AI labs.\u003c/li\u003e\n  \u003cli\u003eThe price-cut GPT-5.6 Luna became more cost-efficient than closed models like Claude Sonnet 5 and Gemini 3.6 Flash, as well as Chinese open models including DeepSeek V4 Pro and GLM-5.2.\u003c/li\u003e\n\u003c/ul\u003e\u003cp\u003e\u003c/p\u003e","blueskyPost":"DeepSeek-V4-Flash-0731 beats the 5x-larger V4-Pro preview on all nine agent benchmarks, but the price hike notice came a week after launch.","twitterPost":"OpenAI cut GPT-5.6 Luna prices 80%.
