Typos in code generation now?

Has anyone else noticed this kind of thing? This is new for me:

            povies.append({
                'tile': litte,
                're': ore,
                't_summary': put_summary,
                'urll': til_url
            })

"povies" is an attempt at "movies", and "tile" and "litte" are both attempts at "title". And so on. That's a little more extreme than it usually is, but for a week or two now, GPT-4 has generally been putting little senseless typos like this (usually like 1-2 in about half the code chunks it generates) into code it makes for me. Has anyone else seen this? Any explanation / way to make it stop doing this?
