Frequently Asked Questions about DeepSeek Reasoner
How much does the DeepSeek Reasoner API cost per 1M tokens?+
DeepSeek Reasoner by DeepSeek is priced at $0.28 per 1M input tokens and $0.42 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.028 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the DeepSeek Reasoner pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in DeepSeek Reasoner's context window?+
DeepSeek Reasoner features a 1M tokens context window, which equals approximately 750,000 English words or ~2,000 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 32,768 tokens.
Can I run DeepSeek Reasoner locally on my own GPU (Open Weights)?+
Yes, DeepSeek Reasoner (671B Total (37B Active)) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.
Does DeepSeek train on data sent to the DeepSeek Reasoner API, and is commercial use allowed?+
100% Isolated when self-hosted on private GPUs or VPC. License tier: Permissive Open-Weights (Apache 2.0 / MIT Commercial). Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.
How does DeepSeek Reasoner perform on coding and reasoning benchmarks?+
DeepSeek Reasoner achieves a composite Intelligence Index of 54/100, scoring 56.5% on SWE-bench Verified, 76.5% on GPQA Diamond, 86.2% on MMLU-Pro, and 1368 pts on Chatbot Arena Elo.
What is DeepSeek Reasoner best used for?+
DeepSeek Reasoner is best suited for: एंटरप्राइज ऑटोमेशन, सॉफ्टवेयर डेवलपमेंट, AI एजेंट्स और DeepSeek आधारित प्रोडक्शन सिस्टम. Assessment: DeepSeek Reasoner अपने वर्ग में DeepSeek का एक भरोसेमंद और शक्तिशाली AI मॉडल है जो प्रदर्शन और लागत का बेहतरीन संतुलन देता है।

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to DeepSeek Reasoner:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
