OpenAI’s GPT-5.5 Sets New Standards for AI Power and Flexibility
101OpenAI has introduced GPT-5.5, claiming it as its most advanced and capable agentic AI model so far. Launched on April 23, this new version is built specifically to handle real-world tasks more independently. OpenAI emphasizes that GPT-5.5 is designed to plan, use tools, verify its own work, and complete complex jobs with minimal human input.
Unlike previous models, GPT-5.5 is the first major retraining since GPT-4.5. It was developed in collaboration with NVIDIA, utilizing their GB200 and GB300 NVL72 rack-scale systems. This partnership aims to boost the model’s performance and efficiency, making it more practical for business and advanced applications.
Enhanced Capabilities and Benchmark Performance
OpenAI highlights that GPT-5.5 can perform tasks that once required multiple prompts and human adjustments more smoothly and completely. This means users can delegate more work to the AI without constant oversight. It is rolling out to various ChatGPT plans—Plus, Pro, Business, and Enterprise—as well as Codex, with API access becoming available shortly after the launch.
The model’s performance is backed by several benchmark tests. It scores highly on Terminal-Bench 2.0, which evaluates command-line workflows that require planning and tool coordination. GPT-5.5 achieves an 82.7% score, surpassing GPT-5.4’s 75.1% and Claude Opus 4.7’s 69.4%. It also outperforms previous versions on tests involving GitHub issue resolution, with a score of 58.6%. Additionally, on internal benchmarks designed to simulate long, complex tasks, GPT-5.5 shows significant improvements, especially in reasoning over large documents, scoring 74.0% on the MRCR v2 benchmark compared to 36.6% for GPT-5.4.
Cost, Efficiency, and Practical Use
OpenAI also discussed the model’s cost and efficiency. API access is priced at $5 per million input tokens and $30 per million output tokens, which is double the rate of GPT-5.4. However, OpenAI claims GPT-5.5 is more efficient at completing tasks, often using fewer tokens. This means that, in practice, the higher price might be offset by reduced task retries and faster completion times. Independent testing confirms this efficiency boost.
For professional users, OpenAI offers GPT-5.5 Pro at $30 per million input tokens and $180 per million output tokens. This version includes additional processing power for harder problems and leads OpenAI’s web-browsing benchmark, achieving a score of 90.1%. While the model’s higher performance offers potential savings in task iterations, cost-effectiveness depends on specific workload demands. For example, at a monthly output of 10 million tokens, GPT-5.5 costs about $300, compared to Claude Opus 4.7’s $250, making the decision to upgrade a balance between performance needs and budget.
Overall, GPT-5.5 represents a significant step forward in AI capabilities, especially in handling complex, multi-step tasks with minimal human intervention. Its improved benchmarks and efficiency make it a strong candidate for businesses seeking more autonomous AI solutions, though users should carefully evaluate cost versus performance for their specific use cases.
