likewise, suppose you buy a 1gb plan from a mobile isp, then you find a youtube tutorial that you're interested in. the nugget of information you need is 23 minutes in, but you have no way of knowing that upfront, it may not even be there. you can exert some control over how many bytes you send in the headers of the get requests to youtube, but you have little control over how youtube compresses the video you requested. also you download 2 30s ads and a sponsored segment before finding what you were looking for. unfortunately you're now out of data on your plan. do you blame your isp for their shady sales practices? is it youtube's fault? what did you pay for?
You're billed by the hour / mile, you can choose an economy vehicle type, but the Toyota driver kept getting lost, swapping out vehicles, changing the price, when you finally reach your destination, you need another top up.
For example, on Android 17, there is Data Saver mode. Your per-app settings can control mobile data usage, in the background, or unlimited. Your WiFi networks can be individually labeled as metered, non-metered, or automatic. In the YouTube app, there are settings for your video quality, and how to adjust that quality based on your connection, if it is mobile data, or metered WiFi. YouTube Music has its own settings, and since it handles podcasts, you can opt out of video entirely.
Furthermore, there is monitoring of data usage. You can set the time period: for example, my mobile data metering resets on the 9th of the month. You can see usage for each app during that time period, split out between mobile and non-mobile data. I can set a warning threshold and a hard limit for mobile data usage.
I only use free LLMs, and not very much. I've only reached a limit once. But I do see that they have indicators or meters for usage. So perhaps check again, look harder, maybe ask your LLM how you can monitor and restrict token usage.
It should be megatokens.
They have an open source tokenizer on GitHub, they indicate which tokenizer they use per model, and they have a simple to use website that tokenize text and visualize it.
