xAI co-founder Tony Wu abruptly resigned from the company late Monday night, marking the latest departure of a senior executive from Elon Musk's AI venture. Simultaneously, the AI landscape is seeing advancements in agentic AI, with OpenAI upgrading its Responses API and new memory architectures emerging to improve performance and reduce costs. Elsewhere, a campaign urging users to cancel their ChatGPT subscriptions has gained traction, fueled by concerns over political contributions and the use of AI by government agencies.
Wu announced his departure on social media, expressing positive sentiments about his time at xAI. "The current era is one where a small team armed with AIs can move mountains and redefine whats possible," he wrote, potentially hinting at the reasons behind his exit, according to Ars Technica. As of March 2025, xAI reportedly employed 1,200 people, including AI engineers and staff focused on the X social network.
OpenAI's recent updates to its Responses API signal a shift away from limited AI agents, according to VentureBeat. The upgrades include Server-side Compaction and Hosted Shell, allowing developers to access multiple agentic tools with a single call. This development aims to address the limitations of previous AI agents that struggled with context and often "hallucinated" after a few interactions, as noted by VentureBeat.
In another development, teams are exploring alternative memory architectures, such as "observational memory," to improve AI agent performance and reduce costs. This open-source technology, developed by Mastra, cuts AI agent costs by a factor of 10 and outperforms RAG on long-context benchmarks, according to VentureBeat. These advancements are crucial as teams move from short-lived chatbots to long-running, tool-heavy agents.
Meanwhile, a campaign called "QuitGPT" is urging users to cancel their ChatGPT subscriptions. The campaign, highlighted by MIT Technology Review, cites concerns over OpenAI president Greg Brockman's contribution to President Donald Trump's super PAC MAGA Inc. and the use of ChatGPT-4 by the U.S. Immigration and Customs Enforcement (ICE). Alfred Stephen, a freelance software developer, expressed frustration with ChatGPT's coding abilities and replies, which led him to support the campaign.
These developments highlight the dynamic and evolving nature of the AI landscape, with companies and individuals navigating rapid advancements, ethical considerations, and the practical applications of AI across various sectors. MIT Technology Review also announced the launch of a new weekly newsletter, "Making AI Work," which will explore the practical applications of generative AI across different industries.
