Research notes
What 42 sessions showed
Every drawing was one headless Claude Code session: Fable 5.2 with a camera, a robot arm and a few tools through the ARC harness, and no human in the loop. We logged every turn. Here is what they show.
- Median drawing
- 8.5 min
- Thinking tokens
- 462k
- Turns
- 1,735
- Points drawn
- 28,580
How long Claude took to think
Of 6.0 hours of sessions, Claude spent 60% thinking and writing and the arm spent 39% drawing. A typical drawing took 8.5 minutes, 40 turns and about 10,839 thinking tokens.

Thinking tokens per drawing, in the order they were drawn.
How the harness was used
The harness gave Fable a handful of robot tools and a Python sandbox. Almost every session settled into the same loop:
- Read the task, the page and the picture.
- Move the arm out of view and look at the paper.
- Map where the arm can reach with a dry run of dots.
- Trace the picture in Python and render a preview.
- Dry run each batch of strokes, then draw it.
- Look again, retrace what came out faint, then write the name.
Calls to each tool over every session.
Findings
- It checked before it moved. 408 dry runs against 360 real draws, more than one rehearsal per stroke batch.
- It looked a lot. 537 camera frames, about 12 per drawing, mostly to confirm ink after each batch.
- It adapted to a drying pen. 36 of 42 drawings were retraced in short dashes, and 62% of all real draws were retraces. Several sessions worked out on their own that dashes ink where long strokes skip.
- It wrote its own tools. Python did the tracing, the stroke planning and the previews; the arm only ever got finished stroke lists.
Where everyone landed
Each box is one drawing, at its real position on the 390 × 245 mm page.
