A token is a piece of a word. For English, 100 tokens is about 60 to 80 words (Google). In: your prompt, instructions and any pasted text. Out: the answer, including any thinking the model does before it answers. Cache: the part of each prompt that repeats, such as fixed instructions, billed at the lower cached rate.

What people say

The Gemini 4 Argon launch discussion on Hacker News drew about 1,200 comments. Developers were struck by how often the top labs now overtake each other, and by Google’s note that Argon agents are moving large C and C++ codebases to Rust inside Google. Paying subscribers were less happy that new models reach the Gemini app later than the API, and some found Google’s benchmark tables hard to compare, since they show the highest reasoning setting only.

In September 2026, ChatGPT sent 80.48% of the visits that AI chatbots referred to websites and Gemini 10.91%, according to Statcounter: Gemini is the clear second.

Privacy in the Gemini app

Google’s Gemini privacy hub says that depending on your settings, your chats can be used to improve Google services. Even with the Keep Activity setting off, Google keeps chats for 72 hours and may use them, with help from human reviewers, to keep the service safe. Google advises not to enter login or payment information in Gemini chats.
