ChatGPT vs DeepSeek
DeepSeek showed that strong reasoning can be cheap. GPT still sets the pace on many hard tasks and has a much wider lineup. The interesting question isn't which is better, it's when the cheap one is good enough.
Cover everything: images, a huge range of sizes, and top-end reasoning models.
Reason step by step at a very low price, with fewer models and mostly text-only.
Draft with DeepSeek, check the hard parts with GPT, in one thread.
Counts and limits from Portail's live model catalog.
On Portail every reply is charged from the model's real price. DeepSeek models sit in the cheap bands, so they make your allowance last. GPT's flagship and Pro models cost much more per answer. The tables below show each model's cost band.
Most GPT models read images; fewer DeepSeek models do. If your question involves a screenshot or a scanned PDF, start with a vision model, then switch to DeepSeek for the text-heavy follow-ups.
On many reasoning tasks DeepSeek is close for a fraction of the price. GPT's top models still tend to lead on the hardest problems and offer far more variety. Try your own prompt on both.
Yes. Switch models mid-thread and the next one reads the whole conversation, so DeepSeek can draft and GPT can check.
