[API调用] API assistant VS GPTs: The Difference Between Assistant API and GPTs

They both perform the same type of vector retrieval on the provided data. The Assistant can be called externally via the API and is billed by usage; GPT is limited to 50 messages/3 hours but requires paying for a Plus subscription. GPTS is simply an easy-to-use version of Assistant. They are the same technology, just aimed at different markets. GPTS can only be used by Plus members, while the API supports external free use.

Feature Differences
There are differences between the behavior of GPTS and Assistant. Assistant can better remember your conversation, while GPT quickly forgets what you tell it.
Assistant can flexibly choose models, but GPTS can only use the default model; however, Assistant has no image generation capability.
GPTS is an included feature for Plus members; its training and uploaded content are not charged extra.
GPTS is not very stable, has very poor memory, and its functions often degrade.

Scenario Examples
If you want to build an article generation tool, GPTS is the first choice because training articles requires a large amount of training data; this training process is very long and costs a lot. But GPTS is free, though there are certain quantity limits: GPTS is limited to 10 files, each about 8000K. But you also have to endure GPTS's instability and the above-mentioned shortcomings. GPTS's configuration content also has a character limit; although you can easily hand-write prompt engineering to create its functions, once your functions become too complex, a few thousand characters are not enough.

Moderator's Advice
GPTS is only suitable for small tools and suitable for sharing among internal members; it consumes the member's personal usage count, while the API is suitable for developing projects, targeting large-scale users, and operating projects with a free or paid strategy. The overall conclusion is that the free one is small and poor, while the paid API is relatively perfect but indeed expensive.
