## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini

## SKI

SKI is a voice-first coding harness that runs on your Mac. Its premise is that coding agents are now fast enough that the real constraint is human attention: five agents working in parallel still have one pair of eyes reviewing them, and output has outpaced anyone's ability to read it. SKI's answer is to make the interface conversational, so you find out what your agents did by listening rather than reading, and acknowledge them in about the time a spoken reply takes.

The harness sits above agents rather than replacing them. It runs Claude Code, Codex, Cursor, OpenCode, Antigravity and others side by side, each on its own task, using the accounts you already pay for. Because it isn't tied to any model vendor, you can send hard reasoning to an expensive engine and bulk work to a cheap open-weight one. An orchestration layer keeps the context of every project, branch and chat, so you can ask where things stand and get one spoken answer — and chain agents together, such as having one plan a feature and another build it.

Git integration is built in: every chat gets its own branch and isolated worktree, live diffs are visible as agents work, and you can open a pull request by voice. Safety is treated as a design requirement rather than an add-on — SKI reconstructs the instruction it believes you meant from project context, shows it for review before the agent sees it, and asks for confirmation on anything irreversible. Your projects, code and chats stay on your Mac and run on your own agent accounts, while voice audio passes through the cloud for understanding but isn't stored. Pricing keeps text usage free forever, with credits spent only on real-time voice.

**Pricing & Plans:** SKI is free forever for text: unlimited typed chats with every supported agent and project on the Free plan. Voice is credit-based — Free includes 300 voice credits/month and 2 concurrent voice sessions, Pro is $20/month with 2,000 credits and 12 sessions, and Enterprise offers custom team rates. Top-up credits last 12 months.

- **Hands-free voice loop:** Talk to your agents and hear spoken replies in real time, so you can ask for a change, hear the result and answer the follow-up without returning to the keyboard.
- **Cross-project orchestration:** SKI keeps project, branch and chat context across every project, and hands each job to the right agent when you ask where things stand.
- **Git built in:** Each chat gets its own branch and worktree so parallel agents never collide; watch live diffs and open a pull request by voice.
- **Multiple agents, one hub:** Run Claude Code, Codex, Antigravity, OpenCode and others simultaneously, each on its own task, with a notification the moment one needs you.
- **Multilingual commands:** Speak in your own language or mix two; SKI interprets the intent and converts it into a precise instruction for the agent.

**Strengths:** Neutral harness that works with the agent subscriptions you already pay for; Unlimited text usage free forever, with credits only spent on voice; Real-time spoken talkback instead of reading logs; Git branches, worktrees and PRs handled by voice
