Abstract

fetched live from OpenAlex

"The Molson" is a low-barrier, peer-staffed, supervised consumption site located in Vancouver, Canada. In addition to overdose response, this site offers drug checking and a colocated injectable hydromorphone treatment program, and it distributes tablet and liquid hydromorphone to service users at high risk of overdose. Our evaluation suggests benefits of this program in creating service continuums and preventing overdose deaths. From September 2017 to August 2019, the site had 128 944 visits, reversed 770 overdoses, and had no overdose deaths.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
