Returns token offsets, selected tokens, probabilities of tokens post-sampling, and normalized probability of selecting a token pre-sampling (for efficiency purposes). Only for text completions. Chat completions in a later commit. Signed-off-by: kingbri <[email protected]>
Change chat completion and text completion responses to be more flexible. Signed-off-by: kingbri <[email protected]>
Adds chat completion logprob support using OAI's spec. Tokens are not converted to tiktoken here since that will add an extra dependency for no real reason. Signed-off-by: kingbri <[email protected]>
Take a log of the token probs since they're already normalized which reflects the proper value. Also, don't error out if a token prob doesn't exist in the dict and return None instead from zip. Signed-off-by: kingbri <[email protected]>
