Frequently asked questions
Is Phi 4 as good as Perceptron Mk1?
Phi 4 is open-weight and competitive on many tasks, but Perceptron Mk1 may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Can I run Phi 4 locally?
Yes. Phi 4 has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. Perceptron Mk1 is API-only and cannot be self-hosted.
How much cheaper is Phi 4?
Phi 4 costs $0.14/M output vs $1.5/M for Perceptron Mk1 — roughly 11x cheaper via API, and free if you self-host.
Phi 4 vs Perceptron Mk1 — which should I pick in 2026?
Choose Phi 4 if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose Perceptron Mk1 if you want frontier capability through a managed API with zero infrastructure to run.
