Frequently Asked Questions about DeepSeek Chat
How much does the DeepSeek Chat API cost per 1M tokens?+
DeepSeek Chat 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 Chat 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 Chat's context window?+
DeepSeek Chat 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 16,384 tokens.
Can I run DeepSeek Chat locally on my own GPU (Open Weights)?+
Yes, DeepSeek Chat (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 Chat 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 Chat perform on coding and reasoning benchmarks?+
DeepSeek Chat achieves a composite Intelligence Index of 50/100, scoring 54% on SWE-bench Verified, 65% on GPQA Diamond, 79.5% on MMLU-Pro, and 1335 pts on Chatbot Arena Elo.
What is DeepSeek Chat best used for?+
DeepSeek Chat is best suited for: Unternehmensautomatisierung, Software-Engineering, autonome KI-Agenten und DeepSeek-Produktionssysteme. Assessment: DeepSeek Chat von DeepSeek überzeugt durch eine ausgewogene Kombination aus Intelligenz, Geschwindigkeit und Kosteneffizienz.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to DeepSeek Chat:
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.
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.
An open standard created by Anthropic that allows AI applications and agents to connect seamlessly to local filesystems, development environments, and third-party APIs via standardized server interfaces.
A cost and latency optimization where inference providers store pre-computed attention states for repeated prompt prefixes. Reusing cached tokens typically slashes API input costs by 50% to 90% and cuts TTFT substantially.
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.
