Where Do LLMs Get Their Data? Training Sources Explained
When people ask where large language models get their data, they may be referring to several different processes. A foundation model learns broad language patterns during pretraining, an assistant is refined during post-training, a RAG application retrieves documents at request time, and some products can use search or browsing tools to access current information. These mechanisms are related, but they are not interchangeable. A document retrieved by a RAG system is not automatically added to the model's training data, and a model that can browse the web is not continuously retraining itself on every page it opens.

How to Choose the Best Proxy Service for Web Data
Choosing the wrong proxy type can waste budget before a workflow even starts. Some teams pay for rotating residential traffic when one stable datacenter IP would be enough. Others use datacenter routes for location-sensitive testing and then spend hours troubleshooting inconsistent results. The best proxy service is not automatically the provider with the largest IP pool or the lowest advertised price. It is the service whose proxy type, location controls, session behavior, authentication, and pricing model match the work you actually need to run. For regional QA, public web data workflows, backend checks, and authorized testing, ask which setup offers...
How to Check If a Proxy Is Working: Proxy Checker Guide
You set up a proxy, refresh the page, and expect your IP address to change. But the result still shows your original IP, the location looks different from what you selected, or the website behaves as if nothing changed. That does not always mean the proxy is bad. It may mean the proxy was not applied to the browser, the wrong app is being tested, the proxy credentials failed, the lookup database shows a nearby city, or the website is using signals beyond IP address. This guide explains how to use a proxy checker properly, what fields to review, how...
Anonymous Browsing: Real Proxy Anonymity Guide
Incognito mode hides your browsing history from anyone sharing your laptop. It does not hide your scraper from Amazon, your seller account from eBay, or your ad verification run from Meta. For production work, you need to route traffic through a proxy — a rotating exit IP, elite headers with no Via leak, and DNS that stays on-path every session. Here is what anonymous browsing actually changes at the network layer. We look at why Incognito and anonymous web proxy shortcuts fall short, and what you need to spin up before your next scraping or e-commerce workflow goes live. Key...
