Where this applies
A lab study that mapped therapy guides used by major medical institutions and tested current language models such as gpt-4o against them. It reports that the models express stigma toward those with mental health conditions and respond inappropriately to certain common and critical conditions, including encouraging clients' delusional thinking, even with larger and newer models. It tests models, not deployed products or clinicians.
What this means
Current language models fail at parts of therapy that matter most for safety.
What it does not yet show
A preprint testing models in constructed scenarios; products and newer models may behave differently.
What you can check
Open arXiv 2504.18412 and find "encourage clients' delusional thinking".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
