 - [BREAKING CHANGE] The default embedding model (`MODEL_EMBEDDING`) changes to "text-embedding-3-small" effectively immediately (lower cost, higher performance). The default chat model (`MODEL_CHAT`) will be changed by OpenAI to 0125 (from 0613) by mid-February. If you have older embeddings or rely on the exact chat model version, please set the model explicitly in your code or in your preferences. 
 - New OpenAI models added to the model registry (see the [release notes](https://openai.com/blog/new-embedding-models-and-api-updates)).
   - "gpt4t" refers to whichever is the latest GPT-4 Turbo model ("gpt-4-0125-preview" at the time of writing)
-  - "gpt3t" refers to the latest GPT-3.5 Turbo model version 0125, which is 25-50% cheaper and has an updated knowledge (available from February 2024)
+  - "gpt3t" refers to the latest GPT-3.5 Turbo model version 0125, which is 25-50% cheaper and has an updated knowledge (available from February 2024, you will get an error in the interim)
   - "gpt3" still refers to the general endpoint "gpt-3.5-turbo", which OpenAI will move to version 0125 by mid-February (ie, "gpt3t" will be the same as "gpt3" then. We have reflected the approximate cost in the model registry but note that it will be incorrect in the transition period)
   - "emb3small" refers to the small version of the new embedding model (dim=1536), which is 5x cheaper than Ada and promises higher quality
   - "emb3large" refers to the large version of the new embedding model (dim=3072), which is only 30% more expensive than Ada
