DeepTide

DeepTide is an open-source AI coding agent built by A8E Group (via Paean AI) that brings DeepSeek models into a terminal-native workflow. It ships in two flavors: a signed, notarized Swift 6 native binary for macOS 15+ and a cross-platform CLI powered by Zero CLI for Linux, Windows, and macOS. The project is MIT-licensed and its source is publicly available on GitHub under the paean-ai/deeptide repository.

What It Is

DeepTide is a terminal-native agentic coding assistant shaped specifically around DeepSeek's long-context reasoning and streaming capabilities. The name combines "DeepSeek" and "tide" (terminal IDE). Rather than wrapping a chat window, it exposes a disciplined tool harness — file I/O, shell execution, git context, MCP servers, hooks, cron jobs, slash commands, and sub-agents — all governed by a shared tide-spec interface contract. The macOS native build is authored in Swift 6 and weighs roughly 15 MB at idle; the cross-platform CLI runs on Bun at roughly 50 MB resident.

Two Flavors, One Spec

The project maintains two distinct runtimes that share the same tide-spec contract, so hooks and muscle memory transfer between them:

• DeepTide for macOS — Swift 6 native binary, signed and notarized, macOS 15+, installed via a one-line curl script from deeptide.sh. Integrates with Keychain auth, Notification Center, terminal title updates, and Apple hardware power checks.
• DeepTide CLI — Cross-platform (Linux, Windows, macOS), installed via bun add -g deeptide or npm install -g deeptide. A thin redirect to @paean-ai/zero-cli, which contains all CLI source. Provides tide and deeptide aliases.

Local Inference Path

DeepTide is explicitly designed to support private, offline inference on Apple Silicon hardware. The repository includes a native local inference runtime under native/: a hard-forked ds4 DeepSeek V4 Flash Metal engine and dsgo, a local OpenAI/Anthropic-compatible gateway. The site states that MacBook Pro, Mac Studio, and Mac mini are supported targets for local DeepSeek V4 Flash inference, with the Q2 build capped at 64k context and a higher-fidelity Q4_K mixed-precision build (153 GiB) available for hosts with 192 GB+ memory. An asymmetric IQ2_XXS + Q2_K + Q8_0 + F16 quant (80.8 GiB) is documented as a size sweet spot for 128 GB Macs and single 80 GB H100 boxes.

Built-in Capabilities

The agentic loop follows a plan → tool → observe → adapt cycle with streaming output. The README lists:

• 30+ built-in tools covering file I/O, shell, web, tasks, MCP, scheduling, and sub-agents
• 25+ slash commands including /status, /cost, /diff, /init, /permission, and /hooks
• Permission modes: default, accept-edits, plan, and bypass
• A hooks engine with pre/post tool, user-prompt, session, and compaction shell hooks
• Persistent project-scoped memory across sessions
• Sub-agents definable from markdown files in the project
• Plan mode for design-before-execution workflows
• Multimodal context via Paean AI (screenshots and documents described before entering the DeepSeek conversation, using Gemini Flash Lite as a vision bridge)

Ecosystem and Lineage

DeepTide is part of the A8E Group product ecosystem, which also includes Clide (a native Mac terminal), Paean AI (the multimodal model gateway and credit routing platform), and 0.works (a practical AI-native work surface). The CLI runtime traces directly to the open-source a8e-ai/zero-cli repository, which is the authoritative source for the CLI engine, tool catalog, and slash command set. BYOK support allows the CLI to drive any Anthropic-protocol-compatible endpoint — including Zhipu GLM, Volcengine, Qwen, Moonshot, and self-hosted gateways — in addition to the default DeepSeek API path.

Current Status

The GitHub repository was created in May 2026 and last pushed on May 17, 2026, indicating active early development. The install script supports pinning to specific versions (e.g., v0.6.63 is shown as an example) and custom install directories. The project explicitly notes it is not affiliated with or endorsed by Anthropic, Inc. or DeepSeek (Hangzhou) AI Co., Ltd.
