## 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

## Thesaurus – Powered by AI

Thesaurus – Powered by AI rethinks the classic reference tool for the age of language models. Instead of returning only the rigid synonym lists of a traditional dictionary, it accepts ordinary language as input — turns of phrase, slang, acronyms and partial thoughts — and proposes richer alternatives that fit the intent behind what you wrote.

The app lives in a compact Mac window that can be pinned as a floating panel above other apps, so it stays within reach while you write in your editor, browser or chat window. Its results are presented in a leather-textured pane that can be customized across four visual styles, giving the tool a distinctive, desktop-native feel rather than a browser tab.

A major part of version 2.0 is flexibility in how the AI runs. The app can use on-device Apple Intelligence models so lookups work offline without sending text anywhere, and it can also draw on fast cloud models such as Cerebras for quicker responses. Reviews praise the design and everyday usefulness while noting that the local model can feel slower than the cloud option, and that antonyms are not yet included.

**Pricing & Plans:** Free. The app is listed on the Mac App Store at no cost, with no subscription required. Cloud model usage depends on the model provider arrangements built into the app.

- **AI-powered synonym search:** Enter a single term, a phrase, an acronym or slang and get a diverse set of alternative words and similar expressions instead of a fixed dictionary list.
- **On-device and cloud models:** Switch between local Apple Intelligence models for offline private lookups and faster cloud models such as Cerebras for lower-latency results.
- **Pinnable floating window:** Keep the app as a small floating panel above your other windows so the right word is always a glance away while you write.
- **Four customizable window styles:** Choose from multiple leather-textured skins to match the look of your desktop setup.
- **Tiny footprint:** A roughly 14 MB download for macOS that starts quickly and stays out of the way.

**Strengths:** Natural-language input handles phrases, slang, acronyms and idioms, not just single words; On-device Apple Intelligence support means lookups can work offline; Beautiful, minimal Mac-native interface with four customizable styles; Free to download with no subscription

**Limitations:** Local on-device model can respond noticeably slower than cloud models; No dedicated antonyms function, a gap several reviewers have flagged; Requires a recent version of macOS to run
