OpenAI Releases GPT-5.5 and New Workspace Agents for Autonomous Multi-Step Tasks

OpenAI has introduced GPT-5.5, a new model specifically optimized for 'agentic work,' enabling it to handle complex, multi-step tasks requiring planning and autonomous execution. This release, alongside new Workspace Agents, signifies a shift from traditional chatbots to AI systems capable of continuous operation and workflow execution without constant human prompting. Anthropic is also moving in a similar direction with agent-to-agent marketplaces.
