Description
Hi,
I would like to use CTranslate2 to accelerate BLIP2, which uses a soft prompt to generate text with OPT model. https://github.com/salesforce/LAVIS/tree/main/projects/blip2
But I think CTranslate2 is lacking support for soft prompt. It only accepts start_tokens. https://opennmt.net/CTranslate2/python/ctranslate2.Generator.html

Research direction
Start with the Python ctranslate2.Generator documentation and the linked BLIP2/OPT project to understand how soft prompts differ from start_tokens. Determine the required support and its expected behavior for this use case; done means CTranslate2 can accept and use soft prompts for the stated BLIP2 workflow.
