Liquid AI launches d1-ultra decision model, tops Artificial Analysis Decision Index

On October 16, Liquid AI released d1-ultra, positioned as a "decision model" designed to make decisions only without generating text: it takes text and image inputs and directly selects an answer with no output tokens, so billing is input-only at $0.042 per million tokens, roughly $30 per million tasks. The model topped the Artificial Analysis Decision Index with a score of 65, and its cost-performance scatter plot shows outstanding value.

Confirmed

• d1-ultra is a multimodal model supporting text and image inputs across 44 languages
• It ranks first on the Artificial Analysis Decision Index with a score of 65 and passed all tests in its 112-evaluation suite
• Billed input-only at $0.042 per million tokens, roughly $30 per million tasks

Why it matters

• Sharer Joseph Jackson advised not to rely on benchmarks alone and to try the model hands-on, stressing that it is cheap and reliable — a sign of the industry's growing attention to the new category of "decision-specific models"
• The "decision-only output, no output tokens" billing and product form represents a novel model design approach that could influence model selection for future decision-making tasks
