## 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

## Open SaaS

Open SaaS packages the tedious, repetitive parts of launching a SaaS into one opinionated template. Instead of wiring auth, billing, file uploads, analytics and email from scratch, you start from a working codebase where those pieces already talk to each other. The stack is React and Node.js with Prisma over Postgres, all orchestrated by Wasp, which generates the glue code and full-stack TypeScript types for you. It is 100% open source and you own every line of code you deploy, so there is no vendor lock-in.

Out of the box it includes pre-configured full-stack authentication that you control, checkout and webhooks for Stripe, Polar.sh and Lemon Squeezy, an admin dashboard with charts and tables, file uploads via AWS S3 presigned URLs, built-in email sending, cron jobs, a Markdown blog built with Astro, and an example AI-powered app wired to a large language model. End-to-end tests with Playwright and a GitHub Actions CI pipeline round out the developer experience.

Because it is built on Wasp, the project keeps pace with AI-assisted development: custom agent rules, skills and tools are provided so coding assistants can work productively inside the repo. It is aimed at solo founders and small teams who want to validate and ship an idea in days rather than months, while still running on a stack they fully understand.

**Pricing & Plans:** Completely free and open source. The template, the Wasp framework and the bundled services are open, and you only pay for third-party services you choose to connect (for example Stripe fees, hosting or an LLM API).

- **Pre-configured Auth You Own:** Full-stack authentication is already wired into the template, including social login flows, so you control the users table and session logic end to end.
- **Multi-Provider Payments:** Checkout and webhooks are pre-built for Stripe, Polar.sh and Lemon Squeezy. Pick a provider and start accepting payments without rebuilding billing each time.
- **Admin Dashboard & Analytics:** A ready-made admin area ships with graphs, tables and analytics integration for Plausible or Google Analytics so you can watch product metrics from day one.
- **AI Example App:** A working AI-powered demo app is included, giving you a concrete pattern for calling a large language model from your own backend.
- **Full-Stack Type Safety & Deploy Flexibility:** Wasp auto-generates TypeScript types across the whole stack, and Playwright E2E tests plus a GitHub Actions pipeline help you deploy anywhere without vendor lock-in.

**Strengths:** Free and 100% open source with no vendor lock-in; Auth, payments, admin, email, uploads and blog pre-wired and integrated; Full-stack TypeScript type safety generated automatically by Wasp; Tuned for AI-assisted development with bundled agent rules and skills

**Limitations:** You must learn Wasp conventions to get the most value from the template; Depends on the Wasp framework and ecosystem staying healthy; Not a hosted product, so you still own deployment, hosting and ops
