## 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

## Dia Browser

Dia rethinks the browser as a workspace assistant rather than a window full of tabs. Instead of bolting a chatbot onto a page, it gives the assistant awareness of your broader context: open tabs, linked Google Workspace or Microsoft Teams content, plus connected tools such as Slack, Notion and GitHub. Practical examples include a Morning Brief that assembles your calendar, inbox and key links before the day starts, a 'Live Work' tab row that surfaces the places work is actually happening, and a Better Meetings mode that opens the right meeting page, agenda, notes and related docs with a countdown so you join on time.

The assistant is designed to produce artifacts rather than just answers. You can ask Dia to turn scattered context into a shareable report, or request a deck and receive real slides with headings, layout and flow that need no redesign. Splits let you place a meeting on one side and a document on the other, and Dia remembers layouts for recurring meetings or focus blocks. Tabs can be grouped automatically with meaningful names such as 'Design Review' or 'Q2 Planning' instead of an unreadable strip. Profiles keep work, freelance and personal browsing — and their AI context — separate, switchable with a swipe.

Privacy is treated as a product feature. Controls are explicit and user-facing: tracker blocking, ad blocking, memory on/off, personalised new chats, and sharing of content data, all toggleable. The company states that data is never sold or used to build ad profiles, that Sync is end-to-end encrypted, and that a separate 'Dia for Work' tier adds SSO and admin tooling for teams. Dia is available as a free download for macOS and Windows, with a release notes and changelog page tracking frequent updates.

**Pricing & Plans:** Free to download and use on macOS and Windows. The company also promotes a 'Dia for Work' offering aimed at teams, which adds enterprise controls such as SSO and admin tools; check the official site for current enterprise terms.

- **Morning Brief:** Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
- **Context-aware answers across tabs and apps:** Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
- **Decks and reports from scattered context:** Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
- **Live Work tab bar:** Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.
- **Profiles and encryption controls:** Separate work, freelance and personal browsing contexts, with tracker/ad blocking toggles and end-to-end encrypted sync.

**Strengths:** AI is built into the browser's core workflow rather than added as a sidebar; Context spans tabs, email, calendars and connected work tools for genuinely useful answers; Outputs are artifacts — reports and slide decks — not just chat responses; Explicit, user-facing privacy toggles plus end-to-end encrypted sync

**Limitations:** Only available on macOS and Windows, with no Linux or mobile release at present; Deep integrations work best inside Google Workspace or Microsoft 365 environments; Heavy reliance on connected data may not suit strict compliance setups without the work tier
