I’ll be interested to see if it stays this way. That’s the only model I’ve seen that pitches “unlimited use without additional cost.”
It’s still not “free,” as the costs are subsidized by the license cost you pay to access D5 Pro - the free tier is limited to a certain number of generations.
If I had to guess, I’d bet that this will not remain as “unlimited use on all paid tiers” in the long run since most AI models calculate cost based on number of tokens used, so the more times users enter a prompt, the higher the cost is for the company.
