15. Interesting Facts and Records
Some remarkable facts about ChatGPT, each with comparison data:
15.1 Fastest App to 100 Million Active Users
ChatGPT reached 100 million monthly active users in just 2 months. No other service has ever achieved this so quickly. Threads (Meta) was downloaded by 100 million people in 5 days, but daily usage collapsed immediately afterward.
15.2 Daily Operating Costs
In early 2023, OpenAI spent an estimated $700,000 per day just to run ChatGPT (SemiAnalysis). Since then, costs have exploded: in 2024, inference costs alone reached around $1.8 billion (roughly $4.9 million per day). Total costs for 2025 are estimated at around $22 billion.
15.3 Training Data
Over 570 GB of compressed text data (approx. 300 billion tokens) was used for GPT-3 (OpenAI GPT-3 paper). Since then, the data volumes have grown massively:
15.4 Energy Consumption per Query
According to an analysis by Epoch AI (February 2025), a typical ChatGPT query (GPT-4o) consumes approximately 0.3 Wh. This is significantly lower than older estimates of 3 Wh (Alex de Vries, 2023), but still roughly 7x higher than a modern Google search (approx. 0.04 Wh).
15.5 GPU Capacity
According to CEO Sam Altman, OpenAI's goal was to have over 1 million GPUs for training and inference by end of 2025 (Tom's Hardware). Other AI companies are also ramping up massively:
15.6 AI-Generated Code
According to GitHub, 46% of code from Copilot users is generated with AI assistance. At launch in 2022, the figure was just 27%. Microsoft CEO Satya Nadella also stated that 20-30% of Microsoft's internal code is now AI-generated.
15.7 ChatGPT in Education
According to Pew Research, use of ChatGPT among US teenagers for schoolwork doubled from 13% (2023) to 26% (2024). A follow-up study (October 2025) shows that 54% of US teenagers already use AI chatbots for schoolwork.
15.8 Fortune 500 Companies
92% of Fortune 500 companies use OpenAI products (ChatGPT, API, or Enterprise). The number of paying business users has grown rapidly:
15.9 Paying Subscribers
