Standout Differences

DeepSeek undercuts on API price

DeepSeek-V3 API pricing runs a fraction of a cent per thousand tokens, dramatically cheaper than ChatGPT or Claude's per-token API rates, making it attractive for high-volume applications.

DeepSeek

Claude Code targets agentic development

Claude Code lets Claude read, edit, and run code across a codebase from a terminal or IDE, a dedicated agentic coding surface that neither ChatGPT's nor DeepSeek's documented feature sets match in depth.

Claude

ChatGPT has the broadest consumer feature surface

Voice mode, image generation, Custom GPTs, Projects, and sandboxed code execution are all bundled into one product, giving ChatGPT the widest range of built-in capabilities among the three.

ChatGPT

Only DeepSeek ships open weights

DeepSeek-V3 and DeepSeek-R1 can be downloaded and self-hosted, an option ChatGPT and Claude don't offer since both remain closed, API- or app-access-only models.

Data governance differs sharply

ChatGPT and Claude both offer enterprise-tier SSO, SCIM, and audit logging, while DeepSeek's hosted consumer app routes data through China-based infrastructure, leading some governments and enterprises to restrict it on official devices.

Frequently Asked Questions

Which is cheapest to run at scale through the API?

DeepSeek, by a wide margin. DeepSeek-V3 is priced at roughly $0.27 per million input tokens and $0.40 per million output tokens, compared to Claude and ChatGPT's per-model API pricing, which runs substantially higher for comparable capability tiers.

Which has the strongest coding agent?

Claude, through Claude Code, which is built specifically for reading, editing, and running code across a codebase from a terminal or IDE. ChatGPT offers coding-agent tools and sandboxed code execution within Plus, while DeepSeek's documented feature set doesn't include a comparable agentic coding product.

Can I self-host any of these models?

Only DeepSeek's models are open-weight and downloadable for self-hosting or fine-tuning. ChatGPT and Claude are closed models accessible only through their official apps and APIs.

Are there data privacy concerns with any of these tools?

DeepSeek's hosted consumer app routes data through China-based infrastructure, which has led some governments and enterprises to restrict or ban the official app on official devices. ChatGPT and Claude both publish enterprise data-handling and compliance options, including workspace data exclusion from training.

Do all three have a genuinely free tier?

Yes. ChatGPT, Claude, and DeepSeek each offer a free chat plan with usage limits, though the specific caps and included capabilities differ across the three.

Which is best for enterprise admin and compliance needs?

ChatGPT and Claude both offer enterprise tiers with SSO, SCIM provisioning, and audit logging. DeepSeek's provided feature set doesn't document equivalent enterprise administration controls.
