What it teaches

Adapters are one of the most practical model-breeding operators. A small adapter can encode a skill without copying a full model. An adapter stack planner helps teams choose base family, adapter order, rank, density, local memory budget, and evaluation scope.

Planner fields

FieldExample
Base modeltinylm-0.5b-instruct

Pseudocode

pseudocode
PROCEDURE plan_adapter_stack(base, adapters, niche)
    REQUIRE SAME_TOKENIZER_AND_LAYOUT(base, adapters)
    stack <- ORDER_ADAPTERS_BY_NICHE_VALUE(adapters, niche)
    footprint <- ESTIMATE_RUNTIME_FOOTPRINT(base, stack)
    evidence <- DEFINE_FITNESS_VECTOR(niche, footprint)
    RETURN ADAPTER_STACK_PLAN(base, stack, evidence)
END PROCEDURE
