What is DeepSeek AI?
DeepSeek AI is an advanced artificial intelligence platform designed to make powerful language models more affordable, accessible, and practical. Unlike some competitors that keep their systems closed, DeepSeek focuses on open-weight models, cost-efficiency, and transparent performance.
DeepSeek has released multiple versions of its flagship model, with DeepSeek V3.1 being the latest (2025). It introduces two operating modes—fast lightweight reasoning for everyday tasks, and deep “thinking mode” for complex problem solving.

DeepSeek V3.1 – Key Features
DeepSeek V3.1 is a major step forward in large language models.
- Dual Modes:
- Non-Think Mode – faster, cheaper, ideal for short queries, casual conversations, and quick lookups.
- Think Mode – slower but capable of multi-step reasoning, planning, and agent/tool usage.
- Long Context Support: Handles up to 128K tokens, perfect for large documents, research papers, or extended conversations.
- Tool & Agent Integration: V3.1 can call external tools, APIs, or “agents” to enhance results.
- Efficiency: DeepSeek emphasizes cost optimization, making it far cheaper than some competitors while maintaining competitive quality.
DeepSeek AI Assistant
DeepSeek also offers its own AI assistant—similar to ChatGPT or Claude—that users can access for everyday tasks like:
- Writing and content generation
- Brainstorming and research
- Translation and summaries
- Question answering
- Problem-solving with reasoning
The assistant can run in fast mode for simple Q&A or deep mode for analytical tasks, giving users flexibility.
DeepSeek Coder – AI for Developers
For programmers, DeepSeek Coder is a specialized model trained on massive code datasets.
- Supports multiple programming languages (Python, JavaScript, C++, Java, etc.)
- Helps with debugging, explaining, and generating code snippets
- Can refactor or optimize existing code
- Assists in building projects faster by suggesting structures and functions
This makes it a strong alternative to GitHub Copilot, GPT-4 Turbo, or Claude for coding.
DeepSeek Pricing (API & Usage)
DeepSeek uses a token-based pricing model. Costs are lower than many competitors:
- Input Tokens (cache hit): $0.07 per 1M tokens
- Input Tokens (cache miss): $0.56 per 1M tokens
- Output Tokens: $1.68 per 1M tokens
⚡ Off-Peak Discounts: DeepSeek introduced special off-peak pricing, lowering costs by up to 75% during certain hours. This makes it extremely budget-friendly for businesses and developers.
How to Use DeepSeek on JanitorAI
Many users integrate DeepSeek V3.1 with JanitorAI, a popular chatbot platform. While there isn’t official one-click support, here’s how it generally works:
- Get API Access: Sign up at DeepSeek’s API page.
- Generate API Key: From your developer dashboard.
- Open JanitorAI Settings: Go to Model / API Settings.
- Insert API Key: Select “Custom API” or proxy option, then paste your DeepSeek key.
- Choose Model: Pick DeepSeek-V3.1 (Think mode for reasoning, Non-Think for speed).
- Test & Adjust: Run a few prompts and fine-tune settings for role-play, creative, or technical use.
⚠️ Note: Some people use unofficial “DeepSeek proxies” to connect JanitorAI. These may work, but they can be unreliable or unsafe. The safest option is official API integration.
