DeepSeek
Open-source reasoning model with strong performance and a generous free tier, plus web search support.
About DeepSeek
DeepSeek is the open-source reasoning model from China that stunned the AI world by matching leading proprietary models at a fraction of the training cost. Its chat interface offers a strong free tier, long context, and web search support.
It is especially good at math, logic, and code — the reasoning-heavy tasks where smaller models usually fail. The open weights mean you can run it locally or through a third-party provider with full control.
For developers and power users who want a genuinely capable model without paying subscription fees, DeepSeek is one of the smartest free options available today.

DeepSeek: strengths and trade-offs
Our own read on the product — written from the vendor’s documentation and our use of it, not from a vendor brief.
What it does well
- Very competitive reasoning and coding quality relative to what it costs — the free chat tier is one of the best value propositions available.
- The API pricing undercuts the major Western providers by a wide margin, which changes what is viable for high-volume workloads.
- Open weights on its mainline models mean self-hosting and fine-tuning are genuinely possible.
Where it falls short
- Servers are frequently busy and responses can be slow or unavailable at peak times.
- Data-handling and jurisdiction questions make it a difficult sell for regulated industries.
- Fewer integrations and a much thinner ecosystem of tutorials and tooling than the market leaders.
Who should skip DeepSeek
- Anyone handling confidential client data under a compliance regime.
- Workflows that depend on deep third-party integration.
