Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored from OpenAI's chatgpt-4o-latest API page (the alias for the GPT-4o snapshot used in ChatGPT; opened this run, now shut down): 128,000-token context = 1; text and image input = 3; $5 input / $15 output per 1M tokens = $7.50 blended at 3:1 = 2.75, rounded to 3 (the page shows the current list price; the August 2024 launch price was not separately opened). Reasoning, coding and speed are null: no Artificial Analysis index or Terminal-Bench figure was opened and OpenAI published no speed; OpenAI said granular benchmarking of this change is an open research problem. Press reported a Chatbot Arena score of 1314, 17 points above Gemini-1.5-Pro-Exp. Independent reviews: 3 found (Tom's Guide, Beebom, DailyAI press reports; no hands-on test of this exact update). developers.openai.com
