DOS AI is an AI API platform for developers and businesses, emphasizing βpay-as-you-go, no hidden fees, and no minimum commitment.β Based on the information on its website, it covers Serverless Inference, Fine Tuning, GPU Cloud, and Detection & Threat Intel API. It can be used not only for standard large language model calls, but also for security-related scenarios such as fraud prevention, AI detection, and eKYC.
Its text and chat models include Llama 3.3/3.1, Mistral Large 2, Mixtral, Qwen 2.5, DeepSeek V3, Gemma 2, and more, with model sizes ranging from 8B to 405B; DeepSeek V3 is a 671B MoE model. The maximum context length is 128K. The page clearly states that all text and chat models support streaming and function calling, which is important for building real-time chat, AI Agent, and tool-calling applications. Its embedding models are suitable for RAG, semantic search, and similarity matching; image generation is available via FLUX.1 and Stable Diffusion XL.
DOS AIβs pricing is relatively transparent. Text/chat models are billed per 1 million tokens. For example, Llama 3.1 8B costs $0.10 for both input and output, Llama 3.1 405B costs $3.50/$3.50, and DeepSeek V3 costs $0.50/$1.50. Embeddings cost $0.008-$0.020 per 1 million tokens. Image generation is charged per image, with Stable Diffusion XL at $0.002/image and FLUX.1 Pro at $0.050/image. New users receive $10 in free credits with no credit card required. Spending limits and usage alerts are supported, and high-volume customers can negotiate volume discounts.
The main advantages are its broad model selection, public pricing, low-friction free trial, and support for streaming output and function calling, making it suitable for quickly validating AI applications. The drawbacks are also clear: the website does not disclose production-critical details such as SLA, latency, concurrency limits, data retention, privacy compliance, SDK availability, or OpenAI compatibility. Fine Tuning, GPU Cloud, and detection-related APIs are also described only at a high level, with limited detail.
DOS AI is a good fit for developers who need low-barrier access to multi-model APIs, RAG application teams, image generation products, and startups looking to control costs. The website does not specify access conditions from mainland China. Payment methods include Visa, Mastercard, American Express, and enterprise invoicing, so domestic Chinese teams should verify network connectivity and payment availability themselves. Alternatives worth considering include OpenAI, Anthropic, Google Gemini, Together AI, Fireworks AI, as well as China-based options such as SiliconFlow, Alibaba Cloud Bailian, and Volcano Ark.
