## 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

## Sofos

Sofos is an "agentic workspace" for business teams built around a simple idea: your documents and your AI agent should live on the same machine and in the same window. One side of the app is a familiar document editor aimed at the kind of writing business teams do all day — product requirements documents, briefs, strategy memos, investor updates and release notes. The other side is an agent that reads and edits those same files, so it works from what you actually wrote rather than from generic training data.

The app is deliberately local-first. Files are stored as plain Markdown in a folder you choose, which means there is no proprietary format and no lock-in — the same files work with tools like Git, Obsidian or VS Code. Rather than bundling its own AI, Sofos connects to an agent you already pay for: Claude Code or Codex, switchable at the bottom of any chat. Because both agents run against your local folder, you can move between them without changing your setup.

Sofos also ships an "Academy" of reusable skills — small Markdown files that teach the agent a repeatable job, such as turning a product brief into Jira epics, assembling a launch kit or building a QBR deck. Around 17 native integrations cover Notion, Linear, Slack, Jira, Confluence, GitHub, Figma, Canva, Asana, Stripe, Supabase and HubSpot. The current release is version 0.1.10 for macOS; the product ships in the open and the team invites direct contact at hello@sofos.co.

**Pricing & Plans:** Sofos is distributed as a free desktop download for macOS, and the company's public site lists no self-serve subscription tiers or prices — the listed pricing model is "contact for pricing." Note that the underlying agent (Claude Code or Codex) is billed separately by the provider you choose. Check sofos.co for the current terms.

- **Editor and agent in one window:** A familiar document editor sits alongside an AI agent that reads and writes the same files, so drafts, edits and research stay in a single place.
- **Bring your own agent:** Sofos does not sell AI. It runs Claude Code or Codex against your local folder using your own subscription, and you can switch between them from the chat footer.
- **Plain Markdown, local-first:** Documents are ordinary Markdown files in a folder on your Mac, compatible with Git, Obsidian and VS Code, with no proprietary format or lock-in.
- **Academy skills:** Downloadable skill files teach the agent repeatable, role-specific jobs such as PRD-to-Jira epics, launch announcement kits and QBR deck builders.
- **17+ integrations:** Connect Notion, Linear, Slack, Jira, Confluence, GitHub, Figma, Canva, Asana, Stripe, Supabase and HubSpot so the agent can pull context from your existing stack.

**Strengths:** Runs on your own machine with plain Markdown files, so there is no data lock-in or proprietary format; Uses the agent subscription you already pay for instead of charging for AI on top; Familiar document editor means no new mental model or migration for business teams; Broad integration list covers the tools most teams already work in

**Limitations:** macOS only, and the current release is an early version (0.1.10) rather than a mature 1.0; No public pricing or self-serve plan details on the site, so costs must be confirmed by contact
