I got Llama 3 8B down over the weekend and it's alright. Not plugged it in to VSCode yet, but I could see it (or code specific derivatives) handling those first two use cases fine. I'd say close enough to be useful.
Let me phrase this another way: Llama 3 400B releases and it has GPT-5 level performance. Obviously; we have not seen GPT-5; so we don't have a sense of what that level of performance looks like. It might be that OpenAI simply has a one year lead, but it might also be that all these frontier model developers are stuck in the same capability swamp; and we simply don't have the compute, virgin tokens, economic incentives, algorithms, etc to push through it (yet). So, Meta pulls ahead, but we're talking about feet, not miles.
