Molders, Shapers, and Casters, Except Metal and Plastic
In short: today's best AI models could do about 0% of this job's working time (projected from METR's April 2026 measurement and Epoch's November 2026 index) if the work were set up for them, and about the same by the end of 2028 if progress keeps its long-run pace. The people and hands-on work, about 100% of the time, stays with people.

Measured use over time
Of the Claude.ai conversations Anthropic sampled and tied to a work task, no reportable share went to this job's tasks in May 2026; 0 of its 24 tasks showed up. Within each of Anthropic's methods, never across a change: 0.058% to 0.017% (released February and March 2025); 0.0059% to 0.0028% (August 2025 to February 2026).

Measured, not estimated: Anthropic's samples of Claude.ai conversations, each tied by a model to an O*NET task, from the Anthropic Economic Index. It says where Claude's use goes, not how much of this job's working time it covers, so it is not on the same scale as the reach above. The releases differ in their sample, their classifier and the smallest share they report (the June 2026 file rounds each task to a hundredth of a percent, so a smaller task reads as none), which is why a change of method starts a new line. At least 96% of each older release's task-tied use matched this site's tasks, and all of the newest. Claude.ai only, so use through other tools and other companies' models is not in it. Every job ranked.
Robots and the physical work
Anthropic rates 96% of this job's working time as physical work. For 90% of the working time, a robot has been shown doing most of the task somewhere: 89% in a purpose-built cell, 1% in a structured facility. 0.91 of 3, the 173rd highest of the 923 jobs.
- Not physical 4%
- No robot shown 6%
- In a purpose-built cell 89%
- In a structured facility 1%
Anthropic's rating, not this site's estimate: Claude Opus 5, searching the web, rated each physical O*NET task by the kind of setting in which a robot it could cite (deployed, sold or demonstrated) does most of the task, weighted by its own estimate of each task's share of the time (What work can robots do?, September 30, 2026, data CC BY 4.0; every job ranked). A robot shown somewhere is not a robot in your building: cost, setup and safety decide that. The share within reach on this page still counts no body work. The robot behind each rated task is under the task below.

Questions about this job
- How much of the work of Molders, Shapers, and Casters, Except Metal and Plastic is within reach of AI now?
- An estimated 0% of the working time is within reach of AI models now and 0% by the end of 2028, on METR's long-run pace at four in five. Within reach means a model could finish work that long at that reliability. It is not a forecast of jobs lost or of savings.
- Which tasks of Molders, Shapers, and Casters, Except Metal and Plastic come within reach first?
- No task has a meaningful share of its time within reach now or by the end of 2028, on the long-run pace at four in five: the work is mostly people work and body work, which the site does not count.
- Which tasks of Molders, Shapers, and Casters, Except Metal and Plastic stay with people?
- Tasks that are people work or body work are not counted as within reach at any date. The largest: Construct or form molds for use in casting clay or plaster objects, using plaster, fiberglass, rubber, casting machines, patterns, or flasks; Align and assemble parts to produce completed products, using gauges and hand tools; and Separate models or patterns from molds and examine products for accuracy. Together such tasks are about 100% of the working time.
- Do people already use AI for the work of Molders, Shapers, and Casters, Except Metal and Plastic?
- In the Claude.ai conversations Anthropic sampled for May 2026, no reportable share went to this job's tasks. Anthropic's labor market measure puts the share of the job's tasks seen in real Claude use at work at 0%. These are measures of use, not of how much of the work AI could finish, and they cover Claude only.
- Can robots do the physical work of Molders, Shapers, and Casters, Except Metal and Plastic?
- Anthropic's robot exposure rating (September 2026) finds 96% of the working time is physical work, and that a robot has been shown doing most of the task, somewhere, for 90% of the working time, 1% in a structured facility. Its index is 0.91 of 3. One example: NUTEC Bickley kiln control/SCADA systems for ceramic kilns for "set the proper operating temperature for each casting". A robot shown somewhere is not one in every workplace; this site's own estimates still count no physical work as within reach.
- How is this estimated?
- From the 24 tasks O*NET lists for the occupation, each with an estimated length checked against GDPval and a share of the working time, each classed as desk, people or body work, and METR's measurements of how long a task the best AI models can finish, carried forward to the date from the latest, Claude Mythos Preview (early) in April 2026. Data checked November 10, 2026.
