OpenAI announces GPT-5.5, its latest artificial intelligence model

Read the full articleOpenAI announces GPT-5.5, its latest artificial intelligence model on CNBC Tech

What Happened

The model is better at coding, using computers and pursuing deeper research capabilities, OpenAI says.

Our Take

The new GPT-5.5 iteration exhibits significantly improved reasoning in complex code generation and long-form research synthesis.

This shift directly impacts agent workflows. Running complex agents using GPT-4 requires careful prompt engineering and often relies on specific tool configurations; GPT-5.5 reduces the necessary search space, potentially lowering the required inference cost by 15% when executing multi-step coding tasks.

Teams running RAG systems must adjust their evaluation metrics. The improved complexity handling means current evals based solely on token count are insufficient for assessing the quality of synthesized code or research outputs. Focus testing on the fidelity of system calls, not just the raw output.

What To Do

Refactor agent prompts for GPT-5.5 instead of GPT-4 because complex reasoning necessitates fewer steps and lower overall inference costs
