AI Newsletter - March 2026
March 2026 marked a pivotal shift in the AI landscape. While the race for larger models continues, this month was defined by a surge in "agentic" models: smaller, faster, and more efficient architectures designed to power autonomous agents and complex workflows. From OpenAI's new GPT-5.4 variants to specialized hardware from Arm, the infrastructure for the next generation of AI agents is being built.
Here is your monthly round-up of the most significant developments in AI.
