DeepSeek

DeepSeek is a Chinese AI research lab known for releasing highly capable large language models as open weights, at a fraction of the training and inference cost typically associated with frontier-scale models. Its models have become widely used in the open-source AI community for their strong reasoning and coding performance relative to their cost.

Common Use Cases

DeepSeek's models are widely used for:

• Self-hosted AI applications: Running a capable open-weight model without relying on a closed API.
• Cost-efficient inference: Achieving strong performance at a lower compute cost than many comparable models.
• Coding & reasoning tasks: Strong performance on coding and multi-step reasoning benchmarks.
• Research & fine-tuning: A frequently used base for further model research and customization.

Key Features & Capabilities

• Open-weight releases: Freely downloadable models that can be self-hosted and modified.
• Mixture-of-experts architecture: Efficient design that activates only a fraction of total parameters per query, reducing compute cost.
• Dedicated reasoning models: Variants specifically tuned for step-by-step reasoning tasks, in addition to general-purpose models.
• Competitive coding performance: Frequently benchmarked strongly against larger, more expensive closed models.

Available Platforms

DeepSeek models can be accessed through:

• Self-hosting: Downloadable open weights via Hugging Face and similar platforms.
• DeepSeek's own API and chat interface: Hosted access for direct use.
