Choosing open-source & self-hosted assistants
Is self-hosting cheaper than a subscription?+
Only at volume or when data control is mandatory. Count GPU time and the hours needed to keep it running.
Can open models match hosted assistants?+
For many everyday tasks yes; for the hardest reasoning tasks the largest hosted models still lead. Test on your own prompts.
