## 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

## OpenAssistantGPT

OpenAssistantGPT is an open-source SaaS platform for building AI chatbots and agents on top of the OpenAI API. Instead of stitching together APIs by hand, you point the platform at your website or upload documents, and it crawls and indexes the content so the assistant can answer questions grounded in your own material. The builder is entirely no-code, and the generated bot can be embedded on a site in a few clicks.

The platform leans on OpenAI's Assistants and Responses APIs, so you can power your bots with models such as GPT-4o and GPT-3.5 and benefit from improvements as OpenAI ships them. Beyond plain Q&A, it supports AI Agent Actions that call API endpoints with specific parameters, web search for fresh information, file attachments for analysis, and lead-capture forms that collect visitor contact details. For workplaces, SAML/SSO authentication can restrict a chatbot to employees only.

Because the project is open source, the code is available on GitHub (including a chatbot SDK for Next.js and Vercel deployment), and the team also runs a changelog documenting ongoing development. Pricing scales from a free tier for personal experiments up to paid plans for organizations running many bots, with enterprise options for compliance and scale.

**Pricing & Plans:** Freemium with four tiers: a Free plan ($0, 1 chatbot, 1 crawler, 3 files, 1 action, 10 messages/month), Basic at $18/month (9 chatbots, 9 crawlers, 27 files, 9 actions, unlimited messages), Pro at $54/month (27 of each, 5 custom domains, whitelabeling), and a custom Enterprise plan priced on request.

- **No-code chatbot builder:** Create a RAG chatbot by giving a URL to crawl or uploading files; no coding or API plumbing required.
- **Powered by OpenAI APIs:** Built on the OpenAI Assistants and Responses APIs, supporting models such as GPT-4o and GPT-3.5 with improved tool calling.
- **AI Agent Actions and web search:** Let the bot query API endpoints with specific parameters and search the web so answers stay current.
- **Enterprise-grade controls:** SAML/SSO authentication for private employee chatbots, lead capture, file attachments, and chat disclaimers.
- **Open source and embeddable:** Source code is on GitHub, and the chatbot can be embedded on popular website platforms with a simple snippet.

**Strengths:** Open source with public GitHub repositories you can self-host or study; Genuinely no-code, from crawling to embedding; Clear feature-based pricing across free, basic, pro, and enterprise tiers; Supports modern OpenAI capabilities like Responses API, actions, and web search

**Limitations:** Tightly tied to OpenAI's API, so you depend on that account and pricing; The free tier is limited to 10 messages per month, suitable mainly for testing; Some advanced integrations require the higher-priced tiers
