OpenAI has hired former Uber Technologies India and South Asia President Prabhjeet Singh as its managing director for India. Singh will join the artificial intelligence company in September, becoming the most senior executive in the region. He will report to Asia Pacific Managing Director Kiran Mani and will oversee consumer growth, enterprise adoption, partnerships, regulatory engagement, and operations.

Singh left Uber last week after more than 10 years at the company. His appointment underscores OpenAI's focus on strengthening its presence in the Indian market and supporting the country's artificial intelligence ecosystem.

Strategic Expansion and Hiring Spree

OpenAI has been aggressively expanding its team as part of its growth plans. The company plans to double its workforce from 4,500 to 8,000 by the end of 2026. Since the start of the year, OpenAI has added 40 employees from Salesforce, reflecting its emphasis on scaling operations and talent acquisition.

Key Executive Appointments

The hiring of Singh is part of a series of strategic leadership changes at OpenAI. Recent appointments include:

Clint Gibler also announced joining OpenAI as a member of the technical staff, working with Michael Aiello, the company's head of product for cyber. These hires highlight OpenAI's commitment to building expertise across policy, product, partnerships, and technical domains.

The Trump administration has reportedly asked OpenAI to limit the distribution of its forthcoming model, GPT-5.6, to a select group of government-approved partners, citing potential security risks. The request from the White House's Office of the National Cyber Director and Office of Science and Technology Policy comes as the administration creates a framework for testing and evaluating the security of new models. OpenAI CEO Sam Altman confirmed the plans for a limited rollout in a memo to staff, stating that this was not the company's preferred long-term model but a necessary step while broader cyber policy frameworks are shaped.

The government's intervention was driven by GPT-5.6's "Mythos-like" capabilities, with a focus on ensuring companies implement adequate safeguards for highly advanced AI models. This follows the administration's clash with Anthropic, which disabled access to its Fable 5 and Mythos 5 models after being directed to block foreign nationals from using them. White House AI and Crypto Czar David Sacks expressed concern that Anthropic's AI models could be exploited as cyberweapons due to advanced cyber capabilities and reported jailbreak vulnerabilities.

OpenAI is introducing three tiers of GPT-5.6—Sol, Terra, and Luna—with the initial rollout restricted to a small group of vetted partners. Access is being delivered first through the API and Codex. At the top end, GPT-5.6 Sol is positioned as the flagship model, adding new reasoning controls like a "max effort" setting and an "ultra" mode that can deploy subagents for more complex workflows. The company highlighted strong benchmark results across coding, biology, and cybersecurity tasks, including performance on Terminal-Bench 2.1 and GeneBench v1.

Security and Safety Features

On the security front, OpenAI says Sol is better at spotting and fixing software vulnerabilities than carrying out full exploit chains. In testing across browsers like Chromium and Firefox, it was able to surface bugs and exploit components but did not independently produce end-to-end working exploits under the conditions evaluated. OpenAI outlined a layered safety system combining training, real-time monitoring during outputs, account-level signals, and tiered access controls. During the preview, some prompts may be slowed or blocked for extra review as the company fine-tunes false positives ahead of wider release.

Testing and Availability

Behind the scenes, OpenAI has logged more than 700,000 A100-equivalent GPU hours on automated red-teaming to probe jailbreaks, alongside external expert testing. The company described a rapid patch cycle to reproduce newly discovered jailbreak methods and fold fixes into future evaluations. Separately, GPT-5.6 Sol is slated to come to Cerebras in July, with throughput of up to 750 tokens per second, though access will start limited as capacity ramps. After the preview phase, OpenAI expects broader availability through ChatGPT, Codex, and its API.
