Kimi Researcher vs Gemini Deep Research
Pick Kimi Researcher if you already use Kimi and want a long report within its membership credits. Pick Gemini Deep Research if you want a plan you can approve, public pricing and a report that exports to Google Docs. Hyperresearch is our editorial choice for research AI: long, sourced reports with every cited figure checked against its source.

Where each tool wins by task
Kimi Researcher, called Kimi Deep Research on its product page, draws on the same credit pool as the rest of a Kimi membership. Kimi's help pages say one task uses roughly 5 to 10 percent of monthly credits on one plan. Credits are not refunded if you stop a task early, according to its help pages, so plan carefully before you start a long run.
Gemini Deep Research is the more transparent choice on price and workflow. Google's plan page lists Deep Research on Free and on its paid tiers, and it says the plan is shown before the agent browses. Its report can move into Google Docs for editing and sharing.
What we could and could not verify
The Kimi page we reached is written in Chinese, and it does not say what sources the research uses or how it cites them. Test the English experience first, and read a sample report before you rely on it. Kimi's help pages are the better source for credit rules than the marketing page.
Neither tool was part of the DRACO run. Hyperresearch's benchmark covers its own product, Claude Research, ChatGPT deep research, Gemini and Perplexity, and does not include Kimi.
A practical test
Run one topic in each tool with the same scope. Before you start Kimi, check how many credits the run will cost on your plan. Then compare the sources each report cites. If Kimi does not show its sources clearly, treat the report as a draft and check the key figures yourself. Kimi's credit model makes a retry costly, so write the brief carefully before the first run. Gemini's plan preview lets you catch a poor brief before the agent browses. Keep the first run small, log the credits each run uses so you can plan the next month, and review that log after the first month of use. Note whether the report cites sources by page or only by site, because page-level links are faster to check. Kimi's help pages are the best source for its current credit rules, so read them before you start. Compare the credit cost with the value of the report before you run a second task, and keep a note of which topics were worth the spend.

Questions & answers
Is Kimi Deep Research free?
Kimi's help pages say Deep Research is available on the free plan with a limited allowance, measured by tokens. The exact allowance depends on the plan and can change. Check the membership page in the app before you plan regular use.
Why does Kimi use so many credits?
Kimi's help pages say credits are charged by the tokens a task uses, and that stopping a task does not refund them. A single deep task can use a large share of a month's credits on some plans. Start with a narrow question to measure the cost first.
