TITLE: OpenAI Launches GPT-5.5 with Stronger Agentic and Computer-Use Capabilities DATE: 2026-04-23 COMPANY: OpenAI TOPIC: Model Releases SUMMARY: OpenAI released GPT-5.5 on April 23, 2026, with significant advances in agentic coding, computer use, and long-horizon task execution. Available to Plus, Pro, Business, and Enterprise users, it carries a 1 million-token context window and is priced at $5 per million input tokens in the API. OpenAI describes it as its smartest and most intuitive model to date. WHAT CHANGED: OpenAI launched GPT-5.5 across ChatGPT and Codex for paid subscribers. The model excels at writing and debugging code, researching online, analysing data, creating documents, operating software, and executing multi-step tasks. API pricing is $5 per million input tokens and $30 per million output tokens, with a 1M context window. The model is also available in a higher-tier GPT-5.5 Pro variant. WHY IT MATTERS: GPT-5.5 closes the gap between human knowledge workers and AI assistants across the most commercially valuable tasks: coding, research, data analysis, and autonomous workflow execution. The release compresses the timeline for AI replacing manual knowledge work inside SMEs. The token efficiency improvements also mean lower total cost despite a higher per-token price compared to GPT-5.4. DAVID & GOLIATH ANALYSIS: This development reinforces our belief that the next generation of organisations will be built on intelligent systems, not larger teams. Operators should evaluate upgrading active GPT-5.4 workflows to GPT-5.5, particularly for agentic coding, research pipelines, and multi-step automations. The 1M context window enables full-document and full-codebase processing in a single call. Test on highest-volume use cases first to quantify token efficiency gains against the higher per-token cost.
