Abstract
We present a novel optically-enabled ball grid array (OBGA) package that integrates conventional electrical I/O, proximity communication (PxC), and optical communication in one industry-compatible BGA package for the first time. The key enabling technologies for such a packaging solution, including the precision alignment needed to combine multiple CMOS chips and compact opto-electronic (OE) subassemblies, are detailed here. We designed and fabricated a 45 mm times 45 mm times 5.2 mm organic cavity-down BGA package with up to 600 solder balls for electrical I/O. Its cavity holds three CMOS chips, with PxC interfaces and optical driver/receiver circuits, as well as two multi-channel optical subassemblies with standard optical fiber connections. We report preliminary testing results.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
