In plain words
DeepSeek R1 is a chat assistant from DeepSeek, a Chinese AI company. It’s an earlier DeepSeek model, and its focus is thinking before it answers: it works through a problem step by step before it replies.
That makes it slower, but steady on sums, schedules and puzzles. It reads PDF documents and helps with code. It doesn’t understand photos and doesn’t search the web.
How to get the most out of it
- Give every number. Amounts, rates, dates and limits. It can only be as exact as your message.
- Ask it to show the working so you can check each step, not just the result.
- List everyone’s limits for rotas and schedules, then ask it to explain its choices.
- Type out text from a photo or use another model, since it can’t read pictures.
How it compares with its siblings
DeepSeek V3.2, DeepSeek V4 Flash and DeepSeek V4 Pro are the other DeepSeek models in chatmodel. They also think before they answer, and all three understand photos too. V4 Flash is the lighter, quicker one; V4 Pro is a newer careful thinker.
When to pick another model
For recent rates or prices, pick a model with web search, like GPT 5.5. For budgets, see our household budget guide. For warm writing, Claude Sonnet 5 is a common choice.
