OpenAI has released a task-specific model guide that helps users pick the right AI model—GPT-4o, o4-mini, or GPT-4.1—based on speed, input type, and reasoning depth.
GPT-4o is the recommended choice for general-purpose usage. It supports text, image, audio and speech inputs, making it a go-to option for tasks such as emails, content writing, translations, and daily chats. Its multimodal capability allows it to process and respond using different input types in the same session.
When conversation needs to reflect emotional awareness, creativity, or tone sensitivity, OpenAI points to GPT-4.5. Though not part of the o-series, GPT-4.5 has been optimized for more thoughtful and imaginative responses. This makes it suitable for brainstorming, storytelling or handling delicate customer interactions.
For users working with complex math, coding, or scientific reasoning, OpenAI recommends the o-series models. These were designed specifically for step-by-step logic, a method known as chain-of-thought reasoning. The o1 model started the series, and o3 expanded on its capabilities. OpenAI’s latest reasoning-focused release, o4-mini, provides fast results with high efficiency. It is suited for STEM tasks that require quick processing and cost-effective compute usage, such as problem solving, visual reasoning, and structured data tasks.
Those looking to build or maintain large-scale software systems are advised to use GPT-4.1 or its smaller variants. These models have been refined for coding accuracy and speed. They outperform previous o-series models in software-related benchmarks and reduce development costs while improving reliability.
According to OpenAI, model selection depends on the type of task, need for multimodality, latency expectations, and budget. GPT-4o is ideal for everyday communication and media-rich input. GPT-4.5 handles nuanced dialogue. o-series models, particularly o4-mini, are tailored for analytical workloads and structured logic. GPT-4.1 is purpose-built for developers working on code-heavy projects.
OpenAI highlighted the importance of matching model capability with task complexity. Heavier reasoning models use more compute and offer greater depth, while lighter models are optimized for speed and cost control. By providing a clear breakdown, OpenAI aims to guide users in aligning their needs with the most effective AI tool.
