100-word summary
OpenAI is rolling out GPT-5.3 Instant as the default ChatGPT model for everyone, even free users. The catch? Free accounts get 10 messages every five hours. Pay $20/month for Plus and you jump to 160 messages every three hours, plus access to GPT-5.4 Thinking for problems that need deeper reasoning. The Thinking model gets a 256K context window, meaning it can digest a short novel's worth of text without forgetting earlier parts of the conversation. Pro subscribers ($200/month) get unlimited access and a 400K window. Free users finally get the latest model, but the tight quota means they'll hit the limit before lunch on anything substantive.
