Detailed Analysis
Claude 4 Sonnet and GPT-5.4 represent the best from Anthropic and OpenAI respectively, but they excel in different areas.
In coding and reasoning, Claude 4 Sonnet has a slight edge. With a coding score of 94 vs GPT-5.4's 92 and reasoning at 90 vs 90, Claude has a narrow lead on complex software engineering tasks. However, GPT-5.4 has closed the gap significantly from previous generations.
GPT-5.4 dominates in multimodal versatility. It supports video and audio input and output natively — something Claude cannot do. For applications needing real-time voice interaction or video content analysis, GPT-5.4 is the better choice.
Pricing favors GPT-5.4 at $2.50/$15 per million tokens compared to Claude's $3/$15. GPT-5.4 also offers twice the max output (32K vs 8K tokens) and a larger 256K context window.
For speed, GPT-5.4 is faster, with a speed score of 80 vs Claude's 78, making it better suited for real-time applications.
