What Is the OpenAI o3‑Pro Model?
Launched in June 2025, o3‑Pro is the advanced variant of OpenAI’s reasoning model family, succeeding the original o3 and o3‑mini . Designed to “think longer” before answering, it tackles deeply complex tasks—math, coding, science, business analysis—with refined logic and precision.
Key Features of the OpenAI o3‑Pro Model
1. Deep, Chain-of-Thought Reasoning
o3‑Pro takes time to break down its thinking process step by step, a method proven to enhance reliability in logic-heavy tasks .
2. Full Tool Integration
It seamlessly integrates web search, file analysis (PDF, code), image processing, Python execution, and memory personalization . Think of it like an AI Swiss Army knife.
3. Superior Accuracy
OpenAI states that expert reviewers prefer o3‑Pro over o3 across all tested domains—especially science, programming, education, business, and writing .
4. Multimodal Input
The model supports both text and image inputs, enabling visual reasoning like OCR, VQA, and analysis of graphs .
5. Cost & Speed Tradeoff
Expect latency of 1–3 minutes per request. API pricing: $20 per million input tokens and $80 per million output tokens—10× higher than standard o3 rates ($2/$8) .
6. Initial Limitations
Currently, o3‑Pro doesn’t support image generation, Canvas, or temporary chats—but those may return soon .
7. Smart Pricing Shift
To offset this premium, OpenAI reduced standard o3 pricing by 80%, now pricing at $2/$8 per million tokens
How Does It Compare?
Model | Pricing (Input/Output) per 1M Tokens | Capabilities |
|---|---|---|
o3‑Pro | $20 / $80 | Deep reasoning, tool use, images, Python |
Standard o3 | $2 / $8 | Powerful reasoning, tool use, cheaper but lighter |
o3‑mini | Varies | Quick, lightweight reasoning with limited tools |
o1‑Pro | $150 / $600 | Previous top-tier model—o3‑Pro surpasses it in performance |
