AI Model Benchmarks
More than 20 frontier models compared on intelligence, agentic coding and cost per task — GPT-5.6 Sol, Terra and Luna against Claude, Gemini, Grok, GLM, DeepSeek, Qwen, Kimi and more. Every figure is real and sourced; unpublished values are shown as “—”, never guessed.
The frontier, ranked
Artificial Analysis Intelligence Index v4.1 composite. Higher is better. GPT-5.6 models are marked.
Intelligence vs cost per task
Intelligence Index against weighted average cost (USD) per Intelligence Index task, log scale. Up-and-left is better value — the shaded region is the most attractive quadrant.
Models are plotted where Artificial Analysis has published both an Intelligence Index and a cost per task. GPT-5.6 models are ringed in white.
