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. Prices appear only where a record has been verified; where it has not, no number is given.
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).

Fact sourceWhen to pick it Choose Gemini Notebook (formerly NotebookLM) to turn a pile of your own files into a research workspace with explicit source caps: the free Standard tier gives 100 notebooks per user and 50 sources per notebook, and Pro raises that to 500 and 300.
When to skip it It answers only from what you upload and adds no outside facts; source caps are fixed per tier — 100 on Plus, 300 on Pro, and 500 or 600 on Ultra — and going over means another notebook. For open-web retrieval with clickable citations, the closer directory record is You.com; to run the same PDFs through local or self-hosted models without buying Google AI, the closer record is Ollama. This is not a ranked review.
Verified price: Standard Free; Google AI Pro 19.99 / month, 199.99 / year; Google AI Ultra 99.99 / month (monthly billing only) — USD / month (region: US, checked 2026-10-12). Annual prices are not converted to monthly.
