grug-35b

grug brain now live in weight. no hidden style stick needed.

July 15, 2026 weight replacement: same public repo, rebuilt weights. Old main preserved on pre-intrinsic-style-fix-2026-07-14. New main makes Grug reasoning intrinsic under ordinary chat and tool-enabled agent prompts.

grug honest rebuild

Earlier main branch could look strongly Grug in ordinary chat because a bundled conditional template injected a style instruction when tools were absent. Tool-enabled agent clients such as OpenCode bypassed that branch, exposing too much normal planner English. This rebuild fixes weight behavior instead of hiding it with prompt steering.

• started from previous merged ProCreations/grug-35b checkpoint
• normal BF16 LoRA, not QLoRA
• multi-pass intrinsic reasoning correction used neutral English agent scaffolds; the final policy repair supervised only the closing-think boundary and exact native tool call from non-held-out real transitions, then retained its delta only on the four dedicated reasoning/tool boundary vocabulary rows
• trained under normal English coding-agent scaffolds and native tool schemas
• original deepreinforce-ai/Ornith-1.0-35B chat template restored without any Grug/style instruction
• intrinsic-style passes adapted the upper shared transformer path; the final tool-boundary repair calibrated only four dedicated boundary rows of the output projection; routed MoE experts remained frozen
• rank 16, alpha 32, LR 1e-05
• final continuation-adapter delta scale 48.0, retained on 4 native-tool vocabulary rows
• final boundary repair: 1,400 non-held-out examples, 160 optimizer steps

unprompted gate

No evaluation request says Grug, requests telegraphic prose, or supplies a style prompt. The suite includes neutral chat, long normal-English agent systems, native tools, and the three exact failure shapes reported after the previous release.

capability retention and tradeoff

Same greedy local harness as prior release: HumanEval 164, MBPP first 100 sanitized test, 18-action card, and 119-action broad tool holdout.

27b and 35b hunt same prey

both grug hunt HumanEval and sanitized MBPP. number show pass@1 percent. bold grug win that hunt.

grug family benchmark

Same prompts, parser, runtime, decoding, and limits for both birds. All numbers are percent; bold marks the best result in each column. Ties make both rocks bold.

grug honest: intrinsic style correction is not free. HumanEval moves down four solved problems (82.9% to 80.5%); MBPP and tool selection improve. Previous weights remain on pre-intrinsic-style-fix-2026-07-14 for anyone preferring that tradeoff.

valid means parser found an offered tool. strict requires exact schema and required arguments. right requires the expected next tool.

Reasoning remains <think>...</think>. Native XML tool shape remains compatible with recent Transformers, vLLM, llama.cpp, and OpenAI-compatible agent clients. Popular rocks: ProCreations/grug-35b-gguf.
