What commenters are saying
Thread speculates on OpenAI cutting inference costs by half, per The Information. Commenters debate the technique: some suggest query caching (dismissed as ineffective for long-tail use), others cite DeepSeek's efficient architectures (V4, DSpark) or diffusion draft models as possible sources. A camp splits on Anthropic CEO Dario Amodei: some call him a villain for hoarding trade secrets, others defend protecting compute multipliers as standard business practice.
