How to start
Pick a DeepSeek model from the model selector. Not sure which model to use? Brainiac is one of the options in the picker and auto-selects for you. You'll always see which model answered.
What DeepSeek is good at
- Coding — writing functions, explaining errors, reviewing snippets.
- Math and logic — working through problems step by step.
- Reasoning tasks where you want the model to show its thinking.
- Everyday questions handled quickly by V3.2.
Reach for V4 Pro on harder technical work; V3.2 is plenty for general tasks. Both are free, so try either.
Tips for better results
- Show your work. Paste the code or the problem in full so it has the full picture.
- Ask it to explain. For learning, request the reasoning, not just the answer.
- Upload files when you're working from a document or dataset.
- Compare models if you want a second opinion on a tricky answer.
