ChatGPT

by OpenAI

OpenAI's AI assistant. Since October 7, 2026 it runs GPT-6 Sol on Plus, Pro, Business and Enterprise and GPT-6 Luna on Free and Go. GPT-6 Astra and GPT-6.1 Sol are available in Codex on Plus and higher.

Good

One app covers chat, image generation (ChatGPT Images 2.5 on every plan), voice and coding (Codex)
GPT-6 Sol on every plan from Plus ($20/mo) up
Go plan at $8/mo is a cheap step up from Free
Three Pro tiers ($100, $200, $500) let heavy users buy more usage without switching tools
Largest ecosystem of custom GPTs and third-party integrations

Watch out

Free and Go run the smaller GPT-6 Luna model
The Go plan may show ads
The strongest models (GPT-6 Astra, GPT-6.1 Sol) are in Codex and ChatGPT Work, not regular chat
Five consumer plans plus three Pro prices make the lineup hard to compare
