Granite 3.x instruct models have their own chat template; without a style they can only be run as GenericBase (bare completion prompt), which measures the missing template rather than the model (granite-3.3-2b-instruct: 4.1 -> 10.6 pass@1 on LCB v6 with the template). The branch mirrors the LLaMa3 one.

Summary
Adds an
LMStyle.GraniteInstructprompt style and registers IBM'sgranite-3.3-2b-instruct/granite-3.3-8b-instruct.Granite 3.x instruct models have their own chat template (
<|start_of_role|>system<|end_of_role|>...). There is currently no style for them, so the only options areGenericBase(a bare completion prompt) or a mismatched chat template. WithGenericBase,granite-3.3-2b-instructscores 4.1 pass@1 on LiveCodeBench v6 (the model mostly ignores the completion-style prompt); with its own chat template it scores 10.6, and every fine-tuned variant we evaluated moved by the same +7 points, i.e. theGenericBasenumber measures the missing template rather than the model.The new branch in
format_prompt_generationmirrors the existingLLaMa3branch: system message + generic question template rendered through the Granite tokenizer'sapply_chat_templatewithadd_generation_prompt=True.Release date for the two entries is set to 2025-04-16 (Granite 3.3 release).
