Our score (0-100) is driven by benchmark performance (90%) from Arena Elo ratings, MMLU, GPQA, HumanEval, SWE-bench, and 15+ standardized evaluations. Capabilities and context window serve as tiebreakers (10%). Learn more about our methodology.
Scores 71/100 (rank #111), placing it in the top 62% of all 290 models tracked.
Scores 89/100 (rank #34), placing it in the top 89% of all 290 models tracked.
GPT-5 Pro has a 18-point advantage, which typically translates to noticeably stronger performance on complex reasoning, code generation, and multi-step tasks.
Choose GPT-4o when you need:
- High-volume production workloads where API costs must be minimized
Choose GPT-5 Pro when you need:
- Processing long documents or large codebases (400K token context)
- Step-by-step reasoning and chain-of-thought problem solving
GPT-4o offers 91% better value per quality point. At 1M tokens/day, you'd spend $187.50/month with GPT-4o vs $2025.00/month with GPT-5 Pro - a $1837.50 monthly difference.
Both models have comparable response speeds. For most applications, the latency difference is negligible.
When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.
Code generation & review
Based on overall model capabilities and architecture for coding tasks like generating functions, debugging, and refactoring
Customer support chatbot
Suitable for user-facing chat with competitive response times. GPT-4o also offers lower per-token costs for high-volume support
Long document analysis
Larger context window (400K tokens) can process longer documents, contracts, and research papers in a single pass
Batch data extraction
Lower output pricing ($10.00/M) reduces costs when processing thousands of records daily
Creative writing & content
Higher overall composite score (89/100) correlates with better nuance, coherence, and style in long-form content
Image understanding & OCR
Supports vision input - can analyze screenshots, diagrams, photos, and scanned documents directly
GPT-5 Pro clearly outperforms GPT-4o with a significant 17.5-point lead. For most general use cases, GPT-5 Pro is the stronger choice. However, GPT-4o may still excel in niche scenarios.
