Image2FloorPlan
Models study several real photos of a home and draw its floor plan. Scored by an average quality score.
In-house Seed evaluation set. The card does not say how the average score is computed, so the scoring field is a guess.

Seed2.1 Pro leads with 48.0
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.
Gemini 3.1 Pro leads with 55.1 across all independent runs
Best score per model across the official leaderboard, Epoch AI’s own runs and any board Epoch AI copied. Each bar and row names its source.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.

One lab put it in a launch post in the last six months
Launch posts from every lab that has listed it, one tick per post. Tall colored ticks include it, and short gray ones leave it out.
| Date | Launch post | Score | As the post writes it |
|---|---|---|---|
| Jun 23, 2026 | Seed2.1 Pro | 48 | Image2FloorPlan (Inhouse), Avg Score |
One system card reports it
Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
| Date | Document | Score | As the document writes it | Section |
|---|---|---|---|---|
| Jun 23, 2026 | Seed2.1 Pro model card | 48 | Image2FloorPlan (Inhouse), Avg Score (Table 3) | Capabilities |
One lab claim next to the leaderboard
Each score a lab reported for its own model, beside the same model's best score on the leaderboard. Gaps mostly come from different harnesses, effort levels and task subsets. Every benchmark.
| Model | Lab says | Board says | Gap |
|---|---|---|---|
| Seed2.1 Pro | 48.0 Image2FloorPlan (Inhouse), Avg Score | 48.0 Leaderboard | Same |
