I ran some tests on phi-3 and mistral-7b and it's not very hard to teach them to use tools, even though they were not designed for this. It turns out these models obey their instructions quite well and when you explain them that if they need to look up data on the net or to perform a calculation, they must formulate this demand with a specific syntax, they do a pretty good job. You just have to enable reverse-prompting so that the evaluation stops after their demand, your tools do the job (or you simulate it manually) and their task continues.
