What is DeepSeek?

DeepSeek is a writing & chat tool — LLM de raisonnement open-weight avec planification à long horizon — performant en mathématiques et en code. It currently sits at #7 on the public 2026 trending leaderboard we track at theresanaiforthat.com.

Out of the box, DeepSeek is built to reason through multi-step problems, open weights, and code.

Who should use DeepSeek?

DeepSeek earns a place on a shortlist for three workflows: teams that need to reason through multi-step problems, solo operators who open weights, and builders who want to code.

How does DeepSeek compare?

In the writing & chat category, DeepSeek sits alongside several alternatives we've reviewed. The closest editorial pick is ChatGPT — OpenAI's flagship chat assistant — the broadest, most-used AI product on earth.

Other tools worth a look in writing & chat: ChatGPT, Claude, Gemini, Grammarly. Each one solves a different cut of the same problem — pricing, hosting model, target user — so the right pick depends on what you actually do most days.

Should you use DeepSeek in 2026?

DeepSeek is on our trending list, sourced from a public leaderboard — which means real users are voting for it, but our editors haven't yet put it through hands-on testing. If you need a verified pick today, ChatGPT is the safer choice.

That said, trending tools earn their position for a reason. If DeepSeek solves a workflow that the curated picks don't, or if it's significantly cheaper, it can be worth trying — most offer a free tier so the cost of a real test is your time, not your wallet.
