Oct 28 (Reuters) - OpenAI will offer its ChatGPT Go

subscription free to users in India for one year starting

November 4, the Microsoft ( MSFT )- backed startup said on

Tuesday, as it seeks to boost adoption in its second-largest

market.

The plan, which was first launched in India in August, is

OpenAI's most affordable offering and is currently priced at 399

rupees ($4.54) per month.

The move comes amid sweeping new rules proposed by the

Indian government earlier this month to regulate artificial

intelligence, proposing that AI and social media firms clearly

label AI-generated content to tackle the spread of deepfake and

misinformation.

India is OpenAI's second-largest market by user base after

the United States and may soon become its biggest, CEO Sam

Altman said earlier this year.

Rival Perplexity is offering a year of free access to its

premium plan to Indian users through a tie-up with mobile

carrier Bharti Airtel, while Google has made

its Gemini AI Pro free for students for the same period.
