Challenge_

The goal was a portable, low-cost AI device without cloud inference. CPU speed, memory bandwidth, thermal limits, storage, and model size make conventional server assumptions unusable.

Approach_

Parallaxis evaluated small quantized models, realistic context limits, streaming generation, local retrieval, thermal design, and a browser interface suitable for an appliance.

Outcome_

The research produced a grounded bill of materials and workload boundary: private document Q&A and narrow assistants are feasible; large-agent workloads and video generation are not.

Overview

The goal was a portable, low-cost AI device without cloud inference. CPU speed, memory bandwidth, thermal limits, storage, and model size make conventional server assumptions unusable.

Parallaxis evaluated small quantized models, realistic context limits, streaming generation, local retrieval, thermal design, and a browser interface suitable for an appliance.

The engineering decision

A useful edge product begins by refusing the wrong jobs. Model selection follows latency and memory measurements, not leaderboard rank.

How the system works

The implementation separates intake, validation, state changes, side effects, and reporting. That separation makes failures visible and allows one layer to change without rewriting the entire workflow.

Operational users see explicit statuses and exceptions; technical teams retain identifiers, timestamps, versions, and logs needed to reproduce a result.
