How to choose for the same task
Both sides belong to the Text Generation category. The conditionals below come from this site's directory records: first check which side's suitability fits your task and which side's exclusions affect you less; if both fit, decide by pricing basis and by how well platforms and formats line up.

ChatGPT
Fact sourceWhen to pick it Open the official pricing page, not an amount on this site, when you need to confirm ChatGPT has a free plan and then compare which of Go, Plus, and Pro includes higher Codex or image limits.
When to skip it The pricing page did not state a plan amount, and it did not say whether non-Search answers include clickable citations; both are unverified. If the job is reading one long document in a single pass, the closer directory record is Claude. If the job is running an open model on your own machine rather than a cloud subscription, the closer record is Ollama. This is not a ranked review.
Exact price not verified. Any pricing-model label describes a billing category, not a verified amount.
DeepSeek
Fact sourceWhen to pick it Choose the DeepSeek API when per-million-token rates have to be costed out for a coding or reasoning workload and you can live with two rate bands, peak and off-peak, plus concurrency caps of 2500 and 500.
When to skip it The page says deepseek-v4-flash and deepseek-v4-flash-vision-exp are retired and now served by DeepSeek-V4.1-Flash at the Flash price, so integrations with a model name or version pinned in code have to change. Vision is flash-only and v4-pro is marked Not supported; if you want open weights to self-host, the closer record in this directory is Qwen, and if you need one long document read rather than a token-billed API, the closer record is Kimi. The page states no region and no commercial licence scope (unverified).
