Have been using GPT-4 for code generation on RTCode.ai for months. It was magical before turbo. It is still the best at complex tasks and vision. GPT-4 did just know what my 10 years-old, extensible, type-and-source-polymorphic, non-linear applicative parser combinator library for F# 3+ would produce given just the examples! (Not even sources or types.) Have also been using Claude 3 Opus recently. Opus follows my style exactly and is better at making edits to longer code. When things get really complex, it tends to fail at tasks where GPT-4 (turbo) still delivers results. Gemini 1.5 Advanced which is a lot faster and sometimes the only one to come up with non-convoluted one-liners that meet the requirements exactly. So, as of today, my experience is, - best vision & complex reasoning: GPT - best style match: Opus - best speed: Gemini
