Palantir’s Valuation Under Fire, Shares Slip

OpenAI Targets India with Low-Cost ChatGPT Plan

Meanwhile in the AI software realm, OpenAI – the startup behind ChatGPT (and heavily backed by Microsoft) – made a notable product move aimed at emerging markets. On Aug. 19, OpenAI launched “ChatGPT Go” in India, a new subscription tier priced at just ₹399/month (≈$4.57) – its cheapest paid plan anywhere reuters.com reuters.com. This India-exclusive plan offers users roughly 10× more messages and image generations than the free tier, plus faster response times, giving budget-conscious customers greater access to advanced GPT-4 capabilities reuters.com. The steep discount (ChatGPT Go is about 80% cheaper than the global $20/month Plus plan) reflects the price-sensitive nature of India’s internet market, which now counts nearly 1 billion users reuters.com. “ChatGPT Go is designed for Indians who want greater access … at a more affordable price,” the Microsoft-supported company said, emphasizing its commitment to India as a growth market reuters.com. OpenAI CEO Sam Altman visited New Delhi earlier this year and even discussed plans to “create a low-cost AI ecosystem” with India’s IT minister reuters.com. India is already OpenAI’s second-largest user base after the U.S., and may soon become the biggest, Altman noted reuters.com. By slashing prices, OpenAI is aiming to rapidly grow its Indian user adoption and fend off rivals as global competition in generative AI heats up. The move also indirectly benefits Microsoft – which integrates OpenAI’s tech into Azure and Office – by expanding the reach of ChatGPT’s ecosystem. Analysts say this pricing strategy could pressure other AI service providers to tailor offerings for high-volume emerging markets. OpenAI’s initiative shows that even as AI firms chase enterprise deals and big contracts, they’re also racing to capture the next billion users with localized products and aggressive pricing.
