GPT-5.5 is designed to consume fewer tokens during operations, but its operational costs remain high. The model's efficiency improvements do not translate to reduced financial expenditure for users.

GPT-5.5 has seen a 2x price increase compared to GPT-5.4, with input tokens rising from $2.50/M to $5.00/M and output tokens from $15/M to $30/M. The model produces shorter completions for the same tasks, impacting overall costs for users.

OpenAI will restrict access to its cybersecurity tool, Cyber, rolling it out initially to "critical cyber defenders." Interested users must submit their credentials and intended use through an application on OpenAI's website to gain access.

OpenAI is launching a Bio Bug Bounty for GPT-5.5, inviting researchers to identify universal jailbreaks that can bypass a five-question bio safety challenge. The initiative aims to enhance safeguards for advanced AI capabilities in biology and is limited to the Codex Desktop model.

OpenAI released GPT-5.5, enhancing the Chat Completions and Responses API for complex professional tasks. Key features include a 1M token context window, image input, structured outputs, function calling, and built-in web search capabilities.

OpenAI's GPT-5.5 is being released freely, offering offensive security capabilities comparable to Anthropic's Mythos, which has limited access. Testing has been conducted across various benchmarks and workflows to evaluate its performance.

GPT-5.5 is a new AI model designed to enhance productivity by understanding user intent more quickly and autonomously completing tasks. It excels in writing and debugging code, researching, analyzing data, creating documents and spreadsheets, and navigating multiple software tools to finish tasks efficiently.
