Qwen2.5-Coder-7B-Instruct-Luau

This model is a fine-tuned version of Qwen/Qwen2.5-Coder-7B-Instruct on the darwinkernelpanic/luaucorpusaxolotl dataset. It achieves the following results on the evaluation set:

—Loss: nan
—Ppl: nan
—Memory/max Active (gib): 14.12
—Memory/max Allocated (gib): 14.01
—Memory/device Reserved (gib): 14.69

Model description

The model was fine-tuned on the Roblox/luau_corpus dataset which was converted to have the "prompt" collum replaced by "text" for compatibility reasons. It was fine-tuned for improved knowledge and performance on Luau code (Roblox's Lua dialect, see luau.org), which should end up improving code quality for Luau and Roblox projects.

Intended uses & limitations

This model is intended for use within applications that use the Luau programming language, including but not limited to

—Roblox projects
—Standalone Luau projects (Lune?)

It may have limitations for projects that

—Use alternative languages
—Use Lua
—Non programming related projects
