GPT-4o
OpenAI flagship multimodal model. Text, images, audio natively. Faster/cheaper than GPT-4. Powers ChatGPT free tier. O-series expanded with o1, o3, o4-mini for reasoning.
GPT-4o is OpenAI's multimodal flagship, natively handling text, images, and audio while undercutting GPT-4 on speed and cost. It powers ChatGPT's free tier, a deliberate move to maximize reach. The model deploys a dense stack of efficiency techniques: Mixture of Experts, Speculative Decoding, FlashAttention, and Rotary Position Embedding. It competes directly with Claude 3 and Gemini, while OpenAI's own o-series (o1, o3, o4-mini) carves out a separate reasoning lane. Endorsed by Ethan Mollick and used by products like Goose and CostRouter, GPT-4o also serves as a judge for other LLMs. It relies on MMLU for benchmarking and deploys Chain-of-Thought and Self-Consistency for reasoning. The tension: can GPT-4o maintain its cost advantage as the o-series cannibalizes its premium use cases?
- ·Multimodal native (text, images, audio) with faster/cheaper inference than GPT-4.

- ·Deploys Mixture of Experts, Speculative Decoding, FlashAttention for efficiency.
- ·Competes with Claude 3 and Gemini; internal competition from o-series reasoning models.
