New Delhi, March 17 : Microsoft-owned OpenAI on Friday announced that ChatGPT Plus, the subscription service to access its text-generating AI, is now available in India. "Great news! ChatGPT Plus subscriptions are now available in India. Get early access to new features, including GPT-4 today," OpenAI said in a tweet. GPT-4, the refined AI model released by OpenAI earlier this week, comes featured in ChatGPT Plus. "We've created GPT-4, the latest milestone in OpenAI's effort in scaling up deep learning," the company said in a blogpost. Compared to GPT-3.5, the new AI model is more reliable, creative and capable of handling complex instructions. GPT-4 outperforms existing large language models (LLMs), including most state-of-the-art (SOTA) models which may include benchmark-specific construction or additional training methods. Moreover, customers on the paid tier gain early access to new features including GPT-4. ChatGPT Plus, which was released in the US in February after a brief preview period, costs $20 per month. A subscription enables a customer to use ChatGPT even during peak usage hours, as well as to receive faster responses and priority access to new features and improvements. However, OpenAI's website still offers a free version of ChatGPT, but with some limitations. If users do not want to pay for access, they can still enjoy the ChatGPT experience by searching for it on Bing. /IANS
