OpenAI launches GPT-5.5 as new flagship model
OpenAI has launched GPT-5.5 as its new main model, designed for "real work and agents." The model offers better token efficiency, supports longer multi-step runs with tool use and self-oversight, and costs about twice as much as GPT-5.4 ($5/$30 per million tokens). API access is delayed due to enhanced security requirements.
WHY IT MATTERS
GPT-5.5 marks OpenAI's next generation of models with a focus on agent autonomy and complex work tasks, which will affect how developers build AI systems. Significant Codex upgrades including browser control and OS integration make the model more practically applicable in production.
