## 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

## Window AI

Window AI takes the position that the model choice should belong to the user, not the website. You install the extension, add the providers you already pay for or run locally, and from then on any compatible site can ask for permission to send a prompt to the model you picked. The extension shows you the request and lets you approve or deny it, which keeps a visible record of where your text is going.

For end users the appeal is portability: set up a local Llama or GPT4All runtime, a Claude key and a GPT-4 key once, and switch between them everywhere. For developers the appeal is different. Instead of paying for and rate-limiting a shared API key, an app can ask the user's browser for a model, which removes a large part of the backend cost and lets users try an app for free with their own credentials. Supported text models at release included GPT-3.5 and GPT-4, PaLM 2 Chat and Code Chat, Claude and Claude Instant, Together's GPT-NeoXT-20B and Cohere Xlarge, plus the open local runtimes, with OpenAI's Shape-E covering early text-to-3D generation.

The extension is free and carries no subscription. Its published build dates from July 2023, so it sits in the early wave of model-agnostic tooling rather than at the cutting edge of today's model landscape; the provider list reflects that era. It remains installable and useful, particularly as an illustration of the bring-your-own-model pattern that later appeared in many AI developer platforms.

**Pricing & Plans:** Free to install and use. You cover only the costs of whichever model provider you connect; local models are free beyond your own hardware. No subscription is sold for the extension itself.

- **Bring your own model:** Configure your models and credentials once inside the extension, then use them on every compatible site without re-entering keys.
- **Cloud and local inference:** Point the extension at hosted providers or at a local runtime such as GPT4All or Llama, keeping prompts on your own machine when privacy matters.
- **Per-site permission prompts:** Compatible apps ask for explicit permission before a prompt is sent, and you can see exactly what is being asked and when.
- **Model-agnostic API for builders:** Developers get a single integration path across OpenAI, Google, Anthropic, Together, Cohere and local runtimes instead of wiring up each API separately.

**Strengths:** One configuration covers every site built on the standard; Supports hosted and local models in the same interface; Explicit permission prompts keep you aware of what is sent where; No extension subscription cost

**Limitations:** No longer actively updated, with the last release from mid-2023; Model list reflects 2023 providers and omits newer frontier models; Adoption depends on developers building against the standard
