Furthermore, OpenAI extended its reach through a partnership with AWS, making GPT-5.5 and GPT-5.4 available via the Amazon Bedrock API in a limited preview, while AWS concurrently launched Codex on Amazon Bedrock and OpenAI-powered Amazon Bedrock Managed Agents.

Google's Agentic Gemini Era at I/O 2026

Google I/O 2026, held on May 19-20, served as the stage for Google to declare the dawn of its "agentic Gemini era." A key highlight was the General Availability of Gemini 3.5 Flash on May 19, which immediately became the default model in AI Mode globally. This move underscored a strategic pivot towards smaller, faster, and more cost-effective models. Google also introduced Antigravity 2.0, a comprehensive agentic development suite featuring Gemini CLI, Code Assist extensions, a desktop app, SDK, and an AI Ultra plan. The unveiling of Gemini Omni showcased its multimodal prowess, capable of combining text, image, and video inputs to generate customized video outputs and AI-generated avatars. Search received sweeping AI upgrades, including a redesigned, multimodal AI-powered search box, "information agents," agentic booking tools, custom AI-generated dashboards, and deeper integrations with Gmail, Photos, and Calendar. The launch of Universal Cart, enabling agentic checkout across Search, Gemini, YouTube, and Gmail, further solidified Google's ambition for pervasive AI integration. Even creative tools like Canva saw expanded design creation capabilities within Google Gemini, while a broad core update for Google Search began rolling out on May 21.

Anthropic's Enterprise and Agentic Push

Anthropic made significant strides in May, particularly with its enterprise and agentic offerings. Claude Opus 4.8 shipped on May 28, bringing notable improvements in agentic coding, reasoning, honesty, and dynamic workflows for parallel sub-agents within Claude Code. The company also launched a new enterprise AI services firm on May 4, backed by investors like Blackstone and Goldman Sachs, aimed at integrating Claude into core business operations. This was complemented by the introduction of ten ready-to-run AI agent templates specifically tailored for financial services workflows, such as pitchbooks and KYC screening. Claude's integration into Microsoft 365 expanded through add-ins for Excel, PowerPoint, Word, and soon Outlook. Furthermore, Anthropic collaborated with Canva to launch Claude Design, a new AI-powered creative workspace, and introduced Claude for Small Business, a workflow system connecting Claude with platforms like QuickBooks, PayPal, HubSpot, Canva, and DocuSign. The month concluded with Anthropic closing a substantial $65 billion Series H funding round, valuing the company at approximately $965 billion.
