Opus 5.5 is currently cheaper than Deepseek V4.1 flash (with APIfied subs, but who cares, that's the price for individuals & startups, unsure why everybody seems obsessed about "API is the price" while it's genuinely not except for Enterprises specifically) - It's quite hard to justify switching outside of the privacy factor.

For us who spends more than $150K tokens a month with less than $5K spending in subs, it's really hard to justify the switch and it's even senseless (for now).
