I've sown pots of Parsley and Basil they are all coming along nicely,

Question is do I thin them out to a single seedling per pot? as in will each little seedling produce a big plant or do I keep them in a pot and treat like the ones from the supermarket?

I've never grown herbs before so excuse my ignorance!!!
