Astra's curve is unusually compact
Astra rises from 49 at $0.63 on low to 55 at $2.57 on max while output-token use increases from 5.4M to 49M. Its medium and high settings sit close to the frontier between intelligence, task cost, and token use.
Artificial Analysis Intelligence Index v4.2 · September 5, 2026 snapshot
Compare GPT-6 Astra, GPT-5.6 Sol, Terra, and Luna, and gpt-oss-120b. In 3D, Intelligence Index is Y, cost per task is X, and output-token use is Z. The 2D view projects cost against intelligence and uses bubble area for token use. Each family has one color and a connected reasoning-effort trajectory where adjacent levels are available.
3D model family view. X = weighted cost per Intelligence Index task. Y = Artificial Analysis Intelligence Index. Z = output tokens from the Intelligence Index evaluation. Drag to rotate and scroll to zoom. Lines only connect adjacent reasoning-effort levels when both points have complete chart data.
Color identifies the model family; labels identify the reasoning level.
2D cost / intelligence projection. X = cost per Intelligence Index task. Y = Intelligence Index. Bubble area represents output-token use, and each family trajectory uses the same color as the 3D view.
Lower and farther right is more expensive; higher is more intelligent. Bubble area indicates output-token use.
Astra rises from 49 at $0.63 on low to 55 at $2.57 on max while output-token use increases from 5.4M to 49M. Its medium and high settings sit close to the frontier between intelligence, task cost, and token use.
Intelligence Index divided by hosted task cost puts gpt-oss-120b low at about 736 Index points/$ and high at 318, compared with about 700 for GPT-5.6 Luna xhigh. That is useful for screening, but not production value: include successful-task rate, retries, latency, token growth, provider limits, and self-hosting or operational costs.
All selected models are retained, including published N/A fields.
