New embedding models and API updates

We are releasing new models, reducing prices for GPT-3.5 Turbo, and introducing new ways for developers to manage API keys and understand API usage. The new models include:

  • Two new embedding models
  • An updated GPT-4 Turbo preview model
  • An updated GPT-3.5 Turbo model
  • An updated text moderation model

By default, data sent to the OpenAI API will not be used to train or improve OpenAI models.

All of this is live now! You can learn more on our latest blog post.

  • embeddings are model-specific; not backwards compatible
  • semantic cosine similarity of new models’ comparisons are different, needing new cutoff thresholds
