OpenAI is granting significant retention bonuses to about 1,000 employees, representing one-third of its workforce, as the competition for AI talent intensifies. The bonuses, valued from several hundred thousand to millions, will be distributed based on performance and seniority. This move coincides with the upcoming launch of GPT-5 and a secondary stock sale expected to raise OpenAI's valuation to $500 billion, indicating its rapid growth amidst fierce industry competition.
