Deep Dive
OpenAI GPT-5
GPT-5 is the current performance king. It scores 95.1% on MMLU and 93.4% on HumanEval, beating both competitors. With a 256K context window, it handles large inputs well. However, it's closed source and expensive at $5/1M tokens. Best for enterprises needing top-tier results.
Anthropic Claude 4
Claude 4 focuses on safety and long-context tasks. While its benchmarks (93.8% MMLU, 90.2% HumanEval) are slightly lower, it excels at maintaining coherence over 200K tokens. Its pricing ($3/1M tokens) is moderate. Ideal for legal, medical, or research use cases where safety is paramount.
Meta LLaMA 4
LLaMA 4 is the open-source champion. With 91.2% MMLU and 87.6% HumanEval, it's competitive but not best-in-class. Its 128K context is smaller, but the cost is unbeatable: free to self-host or $1/1M tokens via API. Perfect for startups, researchers, and privacy-focused users.
Final Verdict
- Performance: GPT-5 wins.
- Context & Safety: Claude 4 wins.
- Cost & Openness: LLaMA 4 wins.
