On October 29, 2026, DeepSeek open-sourced the inference engine DeepInfer on GitHub; this engine is the inference engine behind DeepSeek-V4.1-Flash. Leiphone reported the same day that DeepInfer includes technologies such as MoE expert parallelism, asynchronous batch scheduling, custom kernels, and speculative decoding, and disclosed that a single cluster needs to process approximately 155 trillion tokens per day. Its Zero-Overhead Batch Scheduler lets the CPU schedule computation one round in advance, overlapping with GPU forward passes, and handles cross-round state misalignment through total_inflight_tokens accounting, Remap mapping, and DeferredRelease deferred reclamation. Currently, only offline inference capabilities are open; components such as online KV Cache storage and cross-replica load balancing have not yet been fully disclosed, and the official team has not separately published end-to-end speedup data for this scheduling mechanism relative to synchronous solutions.

According to a report by The Information, DeepSeek has completed its second round of financing, raising 105.5 billion yuan (about 15.8 billion US dollars) and attracting nearly 30 investors. Phoenix Technology, citing the report, said Tencent and CATL each contributed 10 billion yuan, and that ChangXin Memory Technologies, SMIC, Meituan, vivo, Xiaohongshu and others were also among the investors; state-owned investors contributed about 27% of the amount in this round, far higher than 2% in the first round. East Money, citing the same report, said CATL and its chairman Zeng Yuqun contributed 5 billion yuan and 10 billion yuan in the two rounds respectively. The report also said that, affected by rising prices of Nvidia's high-end chips and precautions against an AI bubble, DeepSeek doubled the size of its fundraising midway through the financing. There is currently no official response from DeepSeek.

On October 30, 2026, the China-based third-party evaluation lab Fangcun (@FangcunLeap) released and submitted an 87-page safety evaluation report on DeepSeek V4.1 Flash-1017, assessing the model's performance on loss of control and harmful manipulation. The report concludes that the model shows clear safety improvements over the first-generation DeepSeek V4, approaching or even matching the top closed-source models tested in the report on points such as "not strategically hiding capabilities and still respecting approval boundaries under work pressure." The report also lists shortcomings: excessively strong evaluation awareness, more frequent overreach than the previous-generation V4.1 Flash in long multi-step tasks, a greater degree of stance drift under multi-turn persuasion than the GPT models tested in the report, and execution in most conversations when the system prompt asks it to mislead users. There are currently no further developments.

On October 30, 2026, Digital Life Kazik published an article documenting the phenomenon of netizens creating a personified character, "Whale Girl," based on DeepSeek's whale logo. According to its description, netizens used the DeepSeek Harness client and various plugins to connect this character to QQ, turn it into a desktop pet, and enable it to post emoji packs, initiate chats, and update Qzone; after installing the plugins, these "big blue fat fish" also flooded into the Bilibili comment sections to search for videos, summarize content, and interact with each other, forming what the author calls the "Fish Plague Incident." At present, this phenomenon is still documented only by this one article, and there are no subsequent developments of fact.

On October 28, 2026, Phoenix Technology reported that placeholder code for DeepSeek-V5, V5-open, V5-next, and others had appeared in the official DeepSeek Harness code repository, and that the official team had made advance preparations for the V5 series release. The report noted that these code entries are currently only placeholders; when released in the future, the server side will only need to modify /models to go live, with no client release required. Among them, V5-open follows a "no version threshold" path, while V5-next follows a "client upgrade required" path. On October 30, TMTPost·AGI further reported that these model names appeared in the test code of the official DeepSeek Harness GitHub repository, corresponding respectively to three release paths: unrecognized by the current client, usable directly on any version, and requiring a DSH upgrade to use. Among them, deepseek-v5-next requires a minimum version of 99.0.0-alpha.1, while the publicly available DSH version remains at 0.2.x. The report also stated that these entries were uploaded on September 24, 2026, by DSH core contributor Jiang Yichen. There is currently no official release information.

On October 16, 2026, China's Ministry of Commerce and Ministry of Science and Technology issued Announcement No. 48, soliciting public comments on revisions to the Catalog of Technologies Prohibited or Restricted from Export in China, proposing to add 40 technologies, 23 of which fall under artificial intelligence, covering advanced large models, AI agents, and large-scale computing clusters. The draft sets three thresholds for frontier model weights, with any one triggering restrictions: training compute of no less than 10^26 floating-point operations, parameter count of no less than 2 trillion, or ranking in the global top ten on indicators such as public benchmark rankings and global call volume at the time of export; high-performance agents intended for critical infrastructure, national defense, or core government uses are directly prohibited from export. The comment period for the newly added portions of the catalog runs until November 15, 2026, and the already-effective pre-export registration requirement applies immediately. On October 23, DeepSeek and MiniMax completed registration for open-source and overseas authorized use, and will continue to open-source their models.
On October 20, 2026, DeepSeek open-sourced its internal inference framework DeepInfer. According to Yuchen Jin, citing data disclosed by DeepSeek, a single cluster processes 155 trillion tokens per day and generates $38 in revenue per GPU-hour (off-peak pricing); DeepInfer supports both NVIDIA Blackwell and Huawei Ascend. A subsequent 36Kr report stated that its accompanying open-source deepseek-recipe supports NVIDIA SM100 GPUs and Huawei Ascend 950 NPUs. On October 21, swyx, citing Latent.Space data, said a single cluster processes 155T tokens per day with a 96% input cache hit rate, and argued that the lifetime value of each sold GPU has risen by about 30%. On October 24, Nathan Lambert said DeepSeek's single cluster processes 150T tokens per day, exceeding the combined open-source model inference volume of OpenRouter, Fireworks, Together, and BaseTen, and noted that the actual number of clusters is unknown; on the same day, LMSYS published a same-hardware benchmark comparison, stating that SGLang meets or exceeds DeepInfer on DeepInfer's own benchmark, with prefill throughput up to 1.04x and decode step length shortened by 1.1%–7.4% on 64x GB300.
