The Disappearing AI Middle Class (5 minute read)
Prior to the most recent set of models, LLMs roughly followed a price/performance curve where more expensive models performed better. With the introduction of new top-tier models such as GPT-5.5 and Opus 4.7 which included major price hikes as well as Deepseek V4-Pro and V4-flash which are much cheaper, models have split into expensive, top-tier models and much cheaper models without a clear middle ground. OpenAI argues that the differentiator is that Codex (and similarly the Claude ecosystem) is looking to provide a full stack, whereas other models (such as Deepseek) are just providing one component.
