The Industry Reacts to GPT-5 (Confusing...)

Model Performance & Benchmarks - GPT5 demonstrates varied performance across different reasoning effort configurations, ranging from frontier levels to GPT-4.1 levels [6] - GPT5 achieves a score of 68 on the artificial intelligence index, setting a new standard [7] - Token usage for GPT5 varies significantly, with high reasoning effort using 82 million tokens compared to minimal reasoning effort using only 3.5 million tokens [8] - LM Arena ranks GPT5 as number one across the board, with an ELO score of 1481, surpassing Gemini 2.5 Pro at 1460 [19][20] - Stage Hand's evaluations indicate GPT5 performs worse than Opus 4.1 in both speed and accuracy for browsing use cases [25] - XAI's Grok 4 outperforms GPT5 in the ARC AGI benchmark [34][51] User Experience & Customization - User feedback indicates a preference for the personality and familiarity of GPT-4.0, even if GPT5 performs better in most ways [2][3] - OpenAI plans to focus on making GPT5 "warmer" to address user concerns about its personality [4] - GPT5 introduces reasoning effort configurations (high, medium, low, minimal) to steer the model's thinking process [6] - GPT5 was launched with a model router to route to the most appropriate flavor size of that model speed of that model depending on the prompt and use case [29] Pricing & Accessibility - GPT5 is priced at $1.25 per million input tokens and $10 per million output tokens [36] - GPT5 is more than five times cheaper than Opus 4.1 and greater than 40% cheaper than Sonnet [39]
