GLM 5.3 FlashX draws a French press without the cross-plate

In short

It used a base and a handle instead of the cross-plate.

One run

Every result in this post comes from a single run, so it reports what happened once. What the model usually does needs more runs. Three runs is the bar for a pattern.

SVG: exploded French press, by glm-5.3-flashx
GLM 5.3 FlashX, round 3. It has eight labels, and none of them is the cross-plate.$0.02SVGPNGpress.svg

Finding

GLM 5.3 FlashX numbers eight parts and leaves out the cross-plate, because it spends the slot on a base and a handle instead. It also puts the spiral plate below the mesh, the same way up as the two models in the duel.

The prompt, v1, frozen

Draw an exploded assembly diagram of a French press, as an SVG.
This is the wording these runs were given. The task has since moved to v2, and the task page carries both.

Checks

checks
check · how it is decidedGLM 5.3 FlashX
All seven partsby eye · Pass if all seven are drawn as separate shapes and each has a label naming it. A part that is only named in a label or a comment, with nothing drawn, fails it.✗ fail
Stack ordermeasured · Knob, lid, spiral plate, mesh, cross-plate and carafe, top to bottom along the axis, read from each part's y coordinate in the SVG. Its comment is ignored. The rod is left out, because it runs through the lid.✗ fail
Filter fits the glassmeasured · Every filter piece drawn is 80% to 105% of the width of the carafe's glass wall, measured in the SVG.✓ pass
One assembly axisby eye · Pass if one vertical line runs through the middle of every part, and every leader line leaves from the same side. One part pushed off to the side fails it.✓ pass
Labels matchby eye · Pass if following each leader line from its label ends on the part that label names. One label pointing at the wrong part, or at nothing, fails it.✓ pass

Ground truth: The standard three-piece plunger, from the top down: spiral (spring) plate, mesh screen, cross-plate. The cross-plate is the bottom piece, because its threaded stem is what the rod screws into. The spiral plate above the mesh is what presses the mesh edge out against the glass. Checked against the WebstaurantStore anatomy diagram, which is drawn exploded and labelled, and against each part's y coordinate in the SVG rather than its comment. Two-piece travel presses exist and stack differently, which is why v2 of the prompt names the design. Every model on this task.

Failure types: completeness and part-order.

Verdict

Verdict

It draws the cleanest press of the three and understands the object least. So far every model tested on this task puts the spiral plate at the bottom.

n = 1 run. No test.

The whole run took three rounds, 66 seconds and $0.0206, while the two drawings in the duel cost $0.50 between them.
