* Small LLMs are used for inline AI prompts and chat. They are fast and good for small prompts.
* Medium LLMs are good for medium complexity prompts.
* Large LLMs should be used for large, complex prompts. They involve thinking and chain of thought.
* The LLMs can make mistake in producing the correct hissab expression. Always check the generated expressions.
* If the prompt needs calculations that hissab does not support, the LLMs will try to calculate themselves. This can also happen if the wrong expressions were generated and hissab engine was not able to calculate those expressions.
