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

Our verdict

Choose ChatGPT unless you are in the US and want an assistant that works inside WhatsApp. Muse is new (September 2026), US-only and needs a card even for the free tier; ChatGPT has a longer track record, more tools and a cheaper $8 Go plan. Both charge $20/mo for the first full paid tier.

Is Meta's Muse better than ChatGPT?

Not for most people yet. Muse is new and US-only. ChatGPT offers more tools: images, voice, Codex and custom GPTs.

How much does Muse cost?

Muse is free, with Power at $20/mo and Maximum at $100/mo for more usage. A payment card is required to start, even on the free tier.

What model does Muse use?

Muse runs on Meta's Muse Spark model. ChatGPT runs GPT-6 Sol on paid plans and GPT-6 Luna on Free and Go.

Is Muse the same as Llama?

No. Llama is Meta's older open-weight model family (latest: Llama 4, April 2025). Muse Spark is Meta's newer model family, and Muse is the consumer agent app built on it.
