GPT-4 API common availability and deprecation of older fashions within the Completions API

Functions utilizing the secure mannequin names for base GPT-3 fashions (ada, babbage, curie, davinci) will routinely be upgraded to the brand new fashions listed above on January 4, 2024. The brand new fashions can even be accessible within the coming weeks for early testing by specifying the next mannequin names in API calls: ada-002, babbage-002, curie-002, davinci-002.

Builders utilizing different older completion fashions (corresponding to text-davinci-003) might want to manually improve their integration by January 4, 2024 by specifying gpt-3.5-turbo-instruct within the “mannequin” parameter of their API requests. gpt-3.5-turbo-instruct is an InstructGPT-style mannequin, skilled equally to text-davinci-003. This new mannequin is a drop-in alternative within the Completions API and might be accessible within the coming weeks for early testing.

Builders wishing to proceed utilizing their fine-tuned fashions past January 4, 2024 might want to fine-tune replacements atop the brand new base GPT-3 fashions (ada-002, babbage-002, curie-002, davinci-002), or newer fashions (gpt-3.5-turbo, gpt-4). As soon as this function is obtainable later this 12 months, we’ll give precedence entry to GPT-3.5 Turbo and GPT-4 fine-tuning to customers who beforehand fine-tuned older fashions. We acknowledge that migrating off of fashions which are fine-tuned by yourself knowledge is difficult. We might be offering assist to customers who beforehand fine-tuned fashions to make this transition as clean as potential.

Within the coming weeks, we’ll attain out to builders who’ve lately used these older fashions, and can present extra info as soon as the brand new completion fashions are prepared for early testing.
