Benchmarks
ⓘ Intelligence.ai (formerly DesignArena) publishes this result at product/family scope without an effort setting. It is attached exactly once to muse-spark-1.2::xhigh, the deterministic family representative used by collapsed comparisons; this does not assert that Intelligence.ai tested this specific effort setting.

16 / 73 registered benchmark versions covered · 21 observations including existing index snapshots.
Composite retains Coding Agent v1.4 · source 2026-09-09
The five Composite inputs remain unchanged. Its Coding Agent input is the median across complete harness results in the retained v1.4 snapshot from 2026-09-09. Artificial Analysis now publishes v1.5, with different components. Explore current v1.5 separately. Dated snapshot labels on other indices identify unversioned source captures, not a verified semantic version.
Profile signals
No threshold-crossing signal · 18 eligible benchmark families
How flags are calculated
Heuristic screen, not statistical significance: benchmark families are correlated and source uncertainty is unknown. Peer evidence needs ≥ 20 independently measured matched configurations from ≥ 10 distinct model families. A flag needs a directed population z-score of magnitude ≥ 1.5 and a gap of ≥ 1.5 from the leave-one-benchmark-family-out mean z in the same direction, over ≥ 5 other benchmark families.
Protocol-compatible measured/vendor divergences
No verified protocol-compatible vendor/measured pair is available for this model; agreement cannot be assessed.

Token offers by platform — Adjusted $/task
Adjusted costs are modeled USD per task: AA output tokens × OpenRouter usage I/O (Chutes global fallback). These are general usage and benchmark proxies for coding-agent work. Missing AA data assumes 1,000 output tokens/task; unknown cache hit assumes 0%; unmeasured additional cache writes assume 0 tokens. Click any underlined price for exact inputs, dates and assumptions. Raw list prices use the selected fixed input/output blend, in USD per million tokens.
1 offers within the active global filters; “—” means the catalog is active but no public token price is available.
