Didn't stop them from being extremely successful.
The point is, OpenAI can afford to have free-loaders as long as their deals from enterprise, governments are paying for the service.
Midjourney doesn't have a free plan so no free-loaders there and they're making $200M+ with no VCs.
Stability.ai will always suffer from free-loaders due to their fully open source AI.
Stability's recent models (SD3, SV3D, StableLM2, StableCode, and more) are neither open licensed nor planned for release as open licensed.
GPT-4 cost $100M+ to train (Altman), but Dario Amodei has said next-gen models may cost $1B to train, and $10B models are not inconceivable.
I'd guess OpenAI's payroll is probably $0.5B (770 highly paid employees + benefits, not to mention hundreds of contractors creating data sets).
They're doing what they should: growing the customer base while continuing to work on the next generation of the core technology, and developing the support code to apply what they have to as broad a cross-section of problems as they have the potential to offer a solution for.
