SKY-001 vs GPT-6 Astra: Cost per CAD Task
Updated · Sources linked below
Can I use SKY-001 now? No. Waitlist only, no public API, no price. Skyfall targets commercial deployment in early 2027.
Is “150x cheaper” real? It comes from Skyfall’s own CAD test, not independently verified.
We’ll update this page when Skyfall publishes SKY-001 pricing.

What the numbers mean
Skyfall reports nearly equal CAD shape match for the two models in this test.
The reported time and cost gaps are large, but Skyfall has not disclosed how its per-task costs were calculated.
The absolute BIM shape-match scores remain low for both models.

No public API is available as of October 21, 2026. SKY-001 is waitlist-only. Skyfall targets commercial deployment in early 2027; that is a target, not a confirmed release date.
Skyfall has not published an API price. Its self-reported benchmark lists $0.005 per CAD case and $0.0024 per BIM floor plan. Those benchmark costs are not a public API price, and the per-case cost methodology has not been disclosed.
Skyfall reports similar CAD shape match with lower time and cost in its own test. That does not establish a general advantage over GPT-6 Astra. The results are self-reported, not independently verified, and BIM shape-match scores remain low for both models.
OpenAI lists standard GPT-6 Astra rates at $10 input, $50 output and $1 cached input per 1M tokens. Above 272K input tokens, input and cache rates double and output rates rise by 50% for the full request. Batch processing is 50% off.
