Reviewer scorecard
“No developer API or platform to build on. It's a consumer entertainment product with no B2B play.”
“Revolutionary approach to prompt engineering. Optimizers find better prompts than humans can write manually.”
“Impressive engagement but no path to serious monetization. The safety concerns with younger users are a liability.”
“Steep learning curve and the abstractions can be confusing. For most apps, good prompt engineering is faster.”
“Character.ai has the best understanding of long-context character consistency. That tech could be transformative if applied elsewhere.”
“The idea that prompts should be compiled, not handwritten, is correct. DSPy is ahead of its time.”
