## 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

## Skyelight

Skyelight replaces the familiar mess of screenshots, email chains and Slack messages with feedback that is anchored to the thing being discussed. Reviewers — designers, clients, product managers, freelancers, stakeholders who join as free reviewers — click an element on the real page, from localhost prototype through to production, and drop a comment on it. Each thread carries context such as the component, the source file and line, the branch and the commit, so nobody has to guess what "this button is cut off on iPhone" refers to.

A distinguishing feature is automatic classification: as a comment is typed, Skyelight tags it as a bug, feedback, idea, design inspiration, page copy or another custom type, and you can filter and bulk-manage threads by category. Teams can also publish Claude artifacts and design surfaces into Skyelight so external stakeholders or clients can comment on a hosted link, and everything returns to the same workspace.

What makes it unusual is agent access. An MCP server (and a REST API) is available on every plan, so Claude, Claude Code, Cursor, Codex, Grok, Windsurf, Lovable and Bolt can list open threads, fix them in the codebase and reply on each thread with a link to the commit. The vendor positions this as taking feedback loops beyond Slack, Teams, email and Google Docs while keeping the human review workflow intact for people who like working collaboratively. Skyelight ships a free tier with MCP and REST API included, plus paid Pro and Team plans for heavier use.

**Pricing & Plans:** Freemium. A free plan is available with MCP server and REST API included on every plan; paid tiers are shown on the site (Pro at $29/month and Team at $59/month at the time of review). Annual pricing and enterprise arrangements require contacting the vendor.

- **Element-pinned annotations:** Comment on any element of any page — prototype, staging, localhost or production — so every thread is attached to the exact element it refers to.
- **MCP server and REST API on every plan:** Claude, Claude Code, Cursor, OpenAI Codex, Grok, Windsurf, Lovable and Bolt can list threads, apply fixes and reply with the commit that closed them.
- **Automatic feedback classification:** Comments are classified as they are typed — bug, feedback, idea, design inspiration or page copy — and can be sorted or bulk-managed by type.
- **Client and stakeholder review links:** Publish Claude artifacts or design surfaces to a hosted link; external reviewers join free and their comments land back in your workspace.
- **Rich context on every thread:** Threads carry the pinned component, file path and line number, branch and commit, so developers and agents work in the right place.

**Strengths:** Feedback is anchored to the actual element, so there is no ambiguity about what is being discussed; MCP server and REST API included on every plan, including free; Automatic classification and filtering keeps bug, copy and idea threads separate; Clients and stakeholders can join as free reviewers, keeping costs predictable

**Limitations:** Another tool to introduce into an existing Slack/Teams workflow; Value depends on your team or agent actually reading the threads; Agent integrations need some setup knowledge (MCP configuration, repo access)
