https://dseek.app/news Official-source DeepSeek API and model updates mirrored on an independent timeline. Wed, 04 Nov 2026 13:38:41 GMT https://dseek.app/news#2026-11-03-dsh-0-2-2-alpha-3 https://dseek.app/news#2026-11-03-dsh-0-2-2-alpha-3 Tue, 03 Nov 2026 12:00:00 GMT npm dist-tags for @deepseek-ai/dsh list alpha as 0.2.2-alpha.3, published 3 Nov 2026 07:48 UTC, while latest and next remain 0.2.1-rc.5. This is an alpha pre-release version, not a stable GA release. GitHub marks dsh-v0.2.2-alpha.3 as a pre-release. The release notes unify mouse and keyboard context menus across Sessions, workspaces, and the sidebar; keep a directory tree in file previews; unify code review and worktree access in the experimental change-request and worktree feature (searchable file tree and per-file navigation for local and PR diffs, quote selected code and comments to the Agent, track checks and reviews), folding the standalone Git worktree plugin into it (users who enabled @deepseek-ai/dsh-experimental-tool-worktree must remove it from dsh.profile.bundles); move automation tasks to unified host-level scheduled-task management with manual creation, direct editing, and session-based creation; add a new apply_patch tool (off by default); extend TypeScript and Python SDKs with native commands and plugin management; turn read-before-write and external-change checks off by default while keeping sandbox limits and Review; and include several bug fixes. https://dseek.app/news#2026-11-02-dsh-creator-mode https://dseek.app/news#2026-11-02-dsh-creator-mode Mon, 02 Nov 2026 12:00:00 GMT On 2 Nov 2026 DeepSeek announced and showcased Creator Mode in DeepSeek Harness (dsh). In Creator Mode you describe a plugin in plain language, select the Creator Mode option, and the agent builds the plugin for use inside Harness. DeepSeek published a prompt collection for the seven demo plugins from its announcement video: 3D gallery of famous landmarks, Transformer 3D visualization, DSH pixelated interface, Poster design workbench, Video editing workbench, Paper reader, and Conversation statistics. DeepSeek notes some demos were refined over several rounds of conversation, so one prompt may not reproduce the video exactly. https://dseek.app/news#2026-10-31-dsh-superagent-prototype https://dseek.app/news#2026-10-31-dsh-superagent-prototype Sat, 31 Oct 2026 12:00:00 GMT DeepSeek's Harness team open-sourced dsh-superagent-prototype under the MIT licence (repository description: 'Towards a More Autonomous Agent System'; first commit 31 Oct 2026 12:05 UTC, message 'feat: add the dsh-superagent research prototype'). Per its README, this is a research prototype for reference only, not an official DeepSeek product. It is a proactive coding agent for one GitHub repository, packaged as a bundle for DeepSeek Harness (dsh). It listens to GitHub and optionally Feishu; when an allowed person asks for work it opens a work item, works in its own agent session and directory, and answers in the original conversation (for example with a pull request). A web panel shows what needs a person. Its stated principle is 'take as little human attention as possible, and give as much value as possible'. It accompanies a DeepSeek Harness article 'Exploring Super-agent Design: Towards a More Autonomous Agent System', also posted by @DeepSeekHarness on X on 1 Nov 2026. The published code differs from DeepSeek's internal version and some designs in the article are not implemented. https://dseek.app/news#2026-10-30-dsh-0-2-1-rc-5 https://dseek.app/news#2026-10-30-dsh-0-2-1-rc-5 Fri, 30 Oct 2026 12:00:00 GMT npm dist-tags for @deepseek-ai/dsh list both latest and next as 0.2.1-rc.5, published 29 Oct 2026, while alpha remains 0.2.2-alpha.2 (previously latest pointed to 0.2.1-rc.2).

This is an alpha pre-release version, not a stable GA release. GitHub marks dsh-v0.2.2-alpha.2 as a pre-release. The release notes add rich-text plugin details in the plugin manager with support for updating third-party plugin packages and restoring the previous version if hot updates fail; quoting chat text into the composer; copying a complete conversation as Markdown; interface text and locale configuration for Japanese, Spanish, French, German, Russian, and Brazilian Portuguese; confirming to clear all inactive automation tasks at once while keeping active tasks; and experimental plugins including the subagent_oar tool for delegating independent tasks to local Codex or Claude CLIs, Developer tools statistics for per-turn and per-step context, cache, model, and tool measurements, and Change requests and worktrees for running Sessions in separate Git worktrees with linked PR status and code changes. They also include many mobile, narrow-screen, and sidebar layout and navigation improvements, and raise the default per-image upload limit to 50 MiB. https://dseek.app/news#2026-10-26-dsh-0-2-1-rc-4 https://dseek.app/news#2026-10-26-dsh-0-2-1-rc-4 Mon, 26 Oct 2026 12:00:00 GMT npm dist-tags for @deepseek-ai/dsh list next as 0.2.1-rc.4, published 26 Oct 2026, while latest remains 0.2.1-rc.2.

Per its README, this release covers offline inference, supports DeepSeek-V4.1-Flash (default checkpoint deepseek-ai/DeepSeek-V4.1-Flash-1017), runs on NVIDIA SM100 GPUs and Huawei Ascend 950 NPUs, and includes optimized kernels (FlashMLA, DeepGEMM, DeepEP, TileKernels, DeepSelect, TileLang), attention DP and context parallelism, MoE expert parallelism with EPLB, speculative decoding (DSpark), SWA bounded replay, asynchronous scheduling, batch-invariant inference, deterministic sampling and structured outputs (regex, JSON schema, EBNF). A KV cache system, prefill/decode disaggregation and load balancing are not included. DeepSeek states that inference code for future models will land in the same repository. On the same date DeepSeek also open-sourced deepseek-recipe under the MIT licence: Rust libraries with Python bindings for production token encoding and decoding, converting Messages, Chat Completions and Responses API requests into DeepSeek V4/V4.1 prompts and token IDs aligned with the official DeepSeek API processing so community deployments match hosted behavior. https://dseek.app/news#2026-10-17-dsh-0-2-1-rc-2 https://dseek.app/news#2026-10-17-dsh-0-2-1-rc-2 Sat, 17 Oct 2026 12:00:00 GMT npm dist-tags for @deepseek-ai/dsh list both latest and next as 0.2.1-rc.2, published 17 Oct 2026 (0.2.1-rc.1 was published earlier the same day).
