Use GPT-4.1 for low-latency tool use, GPT-5.2 for planning
Pair GPT-4.1 for fast tool use with GPT-5.2 for deeper, multi-step planning in agentic systems.
GPT-4.1 for reliable tool use and GPT-5.2 for deeper reasoning and planning.
Agentic systems requiring both low-latency tool use and complex multi-step planning.
GPT-4.1 offers low-latency, reliable tool-calling critical for real-time workflows. GPT-5.2 is better suited for deeper, multi-step planning and reasoning when required for complex tasks. Running both within a governed execution layer ensures predictable performance.
The article's publication date
For agentic systems, leverage GPT-4.1 for its speed and reliability in tool-calling for real-time tasks. Utilize GPT-5.2 when more complex, multi-step planning or deeper reasoning is necessary. This dual-model approach, managed by a governed layer, optimizes performance.
