Confronto direto · perfis verificados Oct 5, 2026
Pick ChatGPT for a finished chat app and DeepSeek for a pay-per-token API. ChatGPT has a Free plan, Plus at $20/month and apps for web, desktop and mobile. DeepSeek's documented offer is its API: deepseek-flash starts at $0.15 per 1M input tokens off-peak. We could not verify the DeepSeek chat app's price, free status or privacy terms.
We based this comparison on our ChatGPT profile verified 2026-09-30 and our DeepSeek profile verified 2026-10-05, both built from official vendor pages; it uses no third-party benchmarks and no vendor paid for placement.
ChatGPT is the better-documented choice for everyday chat: it has a free tier, web, desktop and mobile apps, and published business privacy controls. DeepSeek's verified strength is its API, which is billed per 1M tokens and accepts OpenAI- or Anthropic-format requests. We could not verify the DeepSeek chat app's free status, plans or privacy terms, so a like-for-like chat comparison is incomplete. Developers who pay per token should look at DeepSeek; people who want one subscription app should look at ChatGPT.
Based on our ChatGPT profile verified 2026-09-30 and DeepSeek profile verified 2026-10-05; the DeepSeek chat app could not be checked because the site blocked automated access, and no benchmark was run.

For API use, DeepSeek publishes per-token prices, from $0.15 per 1M input tokens off-peak for deepseek-flash. ChatGPT subscriptions are monthly (Plus is $20/month) and its API is billed separately. We could not confirm a DeepSeek chat app price, so a chat-to-chat price comparison is not possible.
Unconfirmed: we could not verify whether the DeepSeek chat app is free. The chat site blocked our automated check, so the free status and plans are unverified. ChatGPT has a documented Free plan with unlimited everyday text chat, subject to guardrails and caps on other tools.
ChatGPT consumer plans may use conversations to improve models unless you turn that off or use temporary chat; Business, Enterprise and API data is not used by default. DeepSeek's training and retention terms were not verified, so check its policy before sharing sensitive data.
ChatGPT and DeepSeek both have an API. OpenAI's API is a separate usage-billed product that no ChatGPT plan includes. DeepSeek's API is billed per 1M tokens and offers OpenAI- and Anthropic-format endpoints, with rates that depend on peak or off-peak hours.
