Training costs heading to $100B per model — Redditor argues frontier AI labs can never be profitable at $20/month

A Reddit long-post questions frontier AI sustainability: citing Amodei's estimate that training costs will jump to $10B and eventually $100B per model by 2027, the author notes the last model likely cost $1B (OpenAI used 400,000 GPUs for Astra). If Anthropic loses $80B every six months, covering it across 40M individual customers means $2,017 extra per person per half-year — about $4K/year for 20 hours of monthly use. Unless labs stop training new models or charge real costs, the author sees no path to profit and doubts $20/month Claude will last.
