Knowledge distillation (validated across the full scale spectrum, from 110M to 2T parameters) and multi-granularity compute routing (intra-model MoE and inter-model task routing) together decouple capability from inference cost along two independent axes: distillation compresses capability into smaller models, while routing allocates compute only where needed — together enabling deployment of frontier-class capability at a fraction of nominal cost.
Justifications
SL — Two independent cost-decoupling mechanisms (compression and conditional computation) operating at complementary levels
Antecedents (all must be IN):
- IN distillation-validated-across-full-scale-spectrum — Knowledge distillation is validated as a scale-invariant capability across the full spectrum of language model sizes: from BERT-scale (DistilBERT retaining 95% performance at 60% of parameters) to frontier-scale (Llama 4 Maverick codistilled from the unreleased ~2T-parameter Behemoth), demonstrating that larger models reliably compress their capability into smaller ones regardless of absolute scale.
- IN compute-routing-operates-at-multiple-architectural-granularities — Compute routing in LLMs operates at two distinct architectural granularities: intra-model routing (MoE activating expert subnetwork subsets per token, as in Llama 4) and inter-model routing (GPT-5 selecting between fast and reasoning models per task), demonstrating that conditional computation is a general efficiency principle applicable at both the parameter level and the model-selection level.
Dependents
These beliefs depend on this one:
- OUT distillation-could-enable-safe-capability-distribution — Knowledge distillation's scale-invariant validation (from 110M to 2T parameters) combined with routing mechanisms that decouple capability from inference cost could enable safe capability distribution — deploying smaller, more controllable models that retain frontier knowledge at accessible cost — provided the information-theoretic inseparability of capability and vulnerability does not propagate through the distillation process itself.
- IN economic-pressure-drives-capability-cost-decoupling — Exponential training cost scaling across model generations creates economic pressure that drives architectural innovations systematically decoupling capability from cost: MoE decouples parameter count from inference compute, knowledge distillation decouples model size from output quality, and compute routing selects granularity per task — all validated across the full scale spectrum from 110M to 2T parameters.
