Llama is arguably the reason open weight LLM’s are a thing, with the leak of Llama 1 and subsequent release of Llama 2. Llama 3 was a huge push for quality, size, context length, and multi-modality. Llama 4 Maverick is clearly better than it looks if a fine tune can put it at the top of LMArena human preferences leaderboard.

Grok 3 mini is quite a decent agentic model and competitive with frontier models at a fraction of the cost; see livebench.ai.
