In short: no. Longer: In theory, but it'll require a bunch of glue and using multiple models depending on the specific task you need help with. Some models are great at working with code but suck at literally anything else, so if you want it to be able to help you with "Do X with Y" you need to at least have two models, one that can reason up with an answer, and another to implement said answer. There is no general-purpose ("FOSS") LLM that even come close to GPT4 at this point.
