OpenAI: gpt-4o-2024-05-13:free

gpt-4o-2024-11-20 is an optimized snapshot of the GPT-4o series. Built on the "Omni" architecture, it natively integrates text, audio, image, and video processing. Compared to earlier snapshots like 0513 or 0806, this version delivers a noticeable boost in creative writing, producing more natural, human-like prose with fewer repetitive patterns. It also shows improved robustness in coding and superior instruction-following, particularly for generating complex structured data (JSON). It remains the industry's most versatile, high-speed, and cost-efficient flagship model for general-purpose AI applications.
