MiniCPM5-2B — Elffuss Code edition (GGUF)
OpenBMB's MiniCPM5-2B, trained a little more every day to work as the coding agent of Elffuss Code — the IDE that runs in your browser: read the project, find the bug, edit the exact lines, check the fix, answer citing real files. A new version is published every day, and every version is measured on the same held-out tasks, so the whole evolution is below.

- Bugs fixed — a one-token bug is planted in a real function of a repo the model never trained on; it counts only if the file ends byte-identical to the original.
- Grounded answers — explaining or locating code, the answer cites a file the tools actually returned.
- Valid tool protocol — every tool call is one Elffuss Code's own parser accepts.
- KLD vs original — drift of the next-token distribution from the original BF16 model on general text (wikitext-2): how much general behaviour the specialisation costs.
Held-out set: 24 tasks on 3 public repos that are never used for training, each run twice, sampled at temperature 1.0 / top_p 0.95 in Elffuss Code's own agent loop (its system prompt, tools and parser, unchanged).
