All these efficiency improvements seem likely to be really important to the future of AI, though, as the money starts flowing the other direction. The days of subsidized tokens to try to lock people into specific ecosystems are coming to an end, and we're going to have to start paying what it actually costs.
The companies that figure out how to make it cost-effective to run really smart models are the ones that will win. DeepSeek costs an order of magnitude less than GPT 5.5 or Opus 4.8. It's worse than either, but not catastrophically worse. I'll happily pay ten times as much for the best coding model, because it saves enough human time to justify it, but not a hundred times as much, which is where things seem to be heading (GPT 5.5 Pro cost over 200 times as much as DeepSeek in some benchmarks I recently did, and ~30 times as much as Opus 4.8).
