> B) potentially phase out Opus, and instead introduce new branding for what they called a "reasoning model" like OpenAI did with o1(-preview)
When should we be using the -o OpenAI models? I've not been keeping up and the official information now assumes far too much familiarity to be of much use.
I think it's first important to note that there is a huge difference between -o models (GPT 4o; GPT 4o mini) and the o1 models (o1-preview; o1-mini).
The -o models are "just" stronger versions of their non-suffixed predecessors. They are the latest (and maybe last?) version of models in the lineage of GPT models (roughly GPT-1 -> GPT-2 -> GPT-3 -> GPT-3.5 -> GPT-4 -> GPT-4o).
The o1 models (not sure what the naming structure for upcoming models will be) are a new family of models that try to excel at deep reasoning, by allowing the models to use an internal (opaque) chain-of-thought to produce better results at the expense of higher token usage (and thus cost) and longer latency.
Personally, I think the use cases that justify the current cost and slowness of o1 are incredibly narrow (e.g. offline analysis of financial documents or deep academic paper research). I think in most interactive use-cases I'd rather opt for GPT-4o or Sonnet 3.5 instead of o1-preview and have the faster response time and send a follow-up message. Similarly for non-interactive use-cases I'd try to add a layer of tool calling with those faster models than use o1-preview.
I think the o1-like models will only really take off, if the prices for it are coming down, and it is clearly demonstrated that more "thinking tokens" correlate to predictably better results, and results that can compete with highly tuned prompts/fine tuned models that or currently expensive to produce in terms of development time.
Agreed with all that, and also, when used via API the o1 models don't currently support system prompts, streaming, or function calling. That rules them out for all of the uses I have.
