I created Luau-Devstral-24B-Instruct-v0.2, a state of the art LLM for Luau code generation. It beats GPT-5 and Claude Opus 4.1 in several key metrics! Get the model and read more details and benchmarks here: https://t.co/DGazRgbWW8

I made an #LLM for #Luau autocomplete! Small, fast, and can run locally on any modern hardware. Not for chatting! It takes the text around your cursor then suggests what you'd write. Check it out: https://t.co/k12r2XLFK9

An insightful metric here is to see how much Mean KLD increases per GB saved- this is essentially measuring the efficiency of the quant. The dynamic quants squeeze a little more out of each GB! (Left logarithmic, right linear. Same values, just including both for readability)

To fit Luau-Devstral-24B-Instruct-v0.2 in smaller GPUs, we can sacrifice quality for size. To reduce that sacrifice, I've created dynamic quantizations based on @UnslothAI's methods! We get a noticeable improvement in quality at similar sizes.

It's hard to describe the feeling of receiving holographic trading cards of yourself. Words can't capture the intense love for the community that these gifts invoke. It's so humbling, validating, and inspiring. Thank you @mprsnd_ & @AlgyLaceyRBLX! ❤️ #RDC2025 #RDC25
