GPT-5.4 hits 1M tokens, computer use
OpenAI has introduced GPT-5.4, a new frontier model for professional and technical work, with GPT-5.4 Thinking in ChatGPT and a Pro tier for heavier workloads. OpenAI says it reaches 83% on its GDPval knowledge-work benchmark while adding up to 1 million tokens of context and native computer-use capabilities in the API and Codex.
// ANALYSIS
The flashy benchmark number grabs attention, but the real story is OpenAI pushing GPT deeper into agent workflows and long-context developer use cases.
- –Native computer use turns GPT-5.4 into a more credible agent backbone for navigating apps, executing multi-step tasks, and verifying outcomes
- –Tool Search matters for builders because it avoids stuffing every tool definition into the prompt, cutting token overhead in larger tool ecosystems
- –A 1M-token context window makes whole-codebase analysis, giant documents, and longer enterprise workflows more practical without aggressive chunking
- –OpenAI is framing this as a reliability upgrade too, with reported drops in claim-level and factual errors versus GPT-5.2
- –The launch keeps pressure on Anthropic and Google in the frontier-model race by tying benchmark gains directly to automation and developer workflow features
