New ChatGPT Features — Pulse, Go, and Atlas

ChatGPT Pulse

ChatGPT Pulse is an innovative feature that conducts research asynchronously on the user's behalf.

How Pulse Works:

Analyzes past conversations, memory, and feedback
Conducts research on the user's behalf once per day
Delivers results as a visual summary the next day

Supported Platforms:

Web
Atlas (browser for Pro users)

ChatGPT Go

ChatGPT Go is a low-cost subscription plan.

ChatGPT Go ($8/month):

Messaging
Image generation
File uploads
Memory features
Available in 171 countries (since August 2025)

Plan Comparison:

Plan	Monthly Price	Key Features
Free	$0	Basic ChatGPT
Go	$8	Image generation, memory, files
Plus	$20	GPT-5.2, priority access
Pro	$200	Unlimited, Sora 2 Pro

Infrastructure Investment — $1.4 Trillion in Ambition

Massive Computing Capacity

OpenAI is making infrastructure investments at an unprecedented scale.

Infrastructure Scale:

Compute capacity: 30+ GW (gigawatts)
Total investment: ~~$1.4 trillion (~~¥200 trillion)
Partners: AMD, Oracle, NVIDIA

Energy Strategy

The energy strategy to support enormous computing resources is equally important.

Energy Mix:

Short-term: Natural gas (especially for the US market)
Long-term: Solar + battery storage
Future: Integration with nuclear power

AI Cloud Platform

CEO Sam Altman has stated: "I want OpenAI to become an 'AI cloud platform' — not just a place for products we release, but a place where others can build the future."

ChatGPT is "the starting point," not the "end point."
