How to Make the Most of GPT-4o

GPT-4o, OpenAI’s “omnimodal” model, is presented as a faster and more cost-efficient successor to GPT-4 Turbo that can understand and generate across text, images, and audio, with video understanding achievable through extracted frames and audio transcription rather than direct video input at the time described. It reportedly responds to audio in roughly human-like conversational time, matches GPT-4 Turbo on English text and coding tasks, improves performance for non-English languages, and offers stronger speech recognition, visual reasoning, document and chart comprehension, and multilingual multiple-choice performance. The article notes a 128K context window, an October 2023 knowledge cutoff, lower token use for many languages, and API pricing of $5 per million input tokens and $15 per million output tokens, compared with double those rates for GPT-4 Turbo. It also provides a Python-oriented API walkthrough covering secure API-key practices, basic chat requests using system and user roles, streaming outputs, image inputs through Base64 data or URLs, and a workaround for video summarization that combines sampled video frames with Whisper-generated audio transcripts.
