OpenAI in Advanced Talks to Acquire Windsurf for $3B
OpenAI is reportedly in late-stage negotiations to acquire AI coding assistant Windsurf for approximately $3 billion. This would represent OpenAI's most expensive acquisition to date and position the company to "own more of the full-stack coding experience." The deal would put OpenAI in direct competition with other AI coding assistant providers, including Anysphere's Cursor (which OpenAI previously backed through its startup fund). An announcement is expected later this week. (TechCrunch, 2025-04-16) (VentureBeat, 2025-04-18)
OpenAI Launches Flex Processing to Reduce AI Costs
In a move to compete more aggressively with rivals like Google, OpenAI has introduced "Flex processing" in beta for its new o3 and o4-mini reasoning models. This API option offers lower pricing in exchange for slower response times and "occasional resource unavailability," providing businesses with more cost-effective options for non-time-sensitive AI tasks.
