OpenAI launched GPT-5.5 and GPT-5.5 Pro, now available via API with updated system cards detailing new safety measures.
The models show significant improvements in agentic coding, computer use, knowledge work, and early scientific research, capable of understanding complex intent and autonomously planning, using tools, and reviewing work.
It achieves higher intelligence while maintaining the same per-token latency as GPT-5.4, requiring fewer tokens to complete the same tasks for greater efficiency.
It features the strongest safety precautions to date, including internal/external red-teaming, targeted testing for advanced cybersecurity and biological capabilities, and feedback from nearly 200 early partners.
It leads in several benchmarks: Terminal-Bench 2.0 (82.7%), GDPval (84.9%), OSWorld-Verified (78.7%), and GeneBench (25.0%).
Rolled out to ChatGPT Plus, Pro, Business, and Enterprise users; API coming soon, priced at $5 per million input tokens and $30 per million output tokens.
Deploys stricter classifiers and safeguards in cybersecurity and offers qualified users more permissive access to capabilities through a "Trusted Network Access" program.
