## 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

## Skylight

Skylight is infrastructure for computer-use agents. Rather than bolting automation onto a local machine, it hosts virtual Windows computers built specifically to be operated by AI, then exposes them through a clean API. The workflow is three steps: get a computer, drive it with agents, and supervise. Each instance comes ready with remote access and can be loaded with the custom applications a workflow depends on.

Agents talk to the machines through the Interactions API, which covers programmatic mouse clicks, keyboard input and screenshots. You can use Skylight's built-in agent, which learns how you like to work over time, or bring your own. Python and TypeScript SDKs can be used natively as an MCP server, which makes the platform a natural fit for agent frameworks. A no-code Playground lets anyone hand the agent a natural-language instruction and watch it act on a live Windows desktop in real time.

Control and scale are treated as core features, not extras. Every computer can be streamed live, safety guardrails restrict what the agent is allowed to do, and the agent asks for confirmation before destructive actions, so a human can intervene at any point. Multiple desktops can run concurrently, instances persist across stop and start, and files created on a virtual machine can be downloaded locally. The vendor reports over 30,000 instances launched and more than 10 million API interactions.

**Pricing & Plans:** Skylight offers a Free tier at $0/month that includes $5 worth of credits, no credit card required, plus unlimited concurrent computers, interactions and file downloads. Pro is $20/month and adds $20 of credits, unlimited file uploads and priority one-to-one support. Enterprise is custom-priced and can run on your own virtual machines. On top of plans, usage is metered: active computers cost $0.005 per minute, hibernated computers $0.0005 per minute, each agent step (screenshot, click, type) costs $0.003, and each file upload or download costs $0.05.

- **Virtual Windows computers on demand:** Spin up virtual Windows instances on demand, each ready to use with remote access and any custom apps your workflow needs.
- **Agentic control via API, SDKs and MCP:** Agents interact through the Interactions API to take screenshots, click, type and send keyboard commands, with Python and TypeScript SDKs and a native MCP server.
- **Human-in-the-loop supervision:** Define safety guardrails, require confirmation before destructive actions, stream all computers live and take over control at any moment.
- **No-code Playground:** Give natural-language instructions to the built-in Windows agent and watch it complete tasks on a real desktop without writing any code.
- **Scale, persistence and file transfer:** Deploy and coordinate many concurrent VMs, stop and resume instances without losing progress, and download files produced on the virtual machine.

**Strengths:** Purpose-built virtual Windows machines for agents instead of fragile local scripting; Free tier with $5 of credits and no credit card required to start; Python and TypeScript SDKs plus a native MCP server fit modern agent stacks; Human-in-the-loop confirmation, live streaming and guardrails reduce automation risk

**Limitations:** Metered consumption (per-minute VMs plus per-step agent actions) can be harder to forecast than a flat seat price; Focused on Windows-only virtual computers, so macOS or Linux workloads need other tooling; Fully guarded, large-scale automation is best supported through the SDKs, which assumes some developer skill; Enterprise pricing for deploying on your own VMs is custom and requires contacting sales
