Compare against
Your current scheduler on the same model and hardware.
- Locate the paper's implementation and check its license, model support, data needs, and hardware requirements. Stop here if you cannot obtain the required artifacts.
- Save a small set of representative product tasks and expected outcomes. Keep evaluation tasks out of any training or tuning, and choose quality and cost limits before running.
- Run the baseline and the proposed change on identical inputs. Keep other settings fixed and repeat paired runs to expose variation.
- Save per-task outputs, failures, timings, and all usage costs. Review regressions before expanding the test.
What to measure
Requests meeting your latency target, throughput, failures, and cost per successful request.
When to keep it
Keep the change only if it meets your preselected quality and latency limits and improves the metric you care about after setup and operating costs. Otherwise retain the baseline. This is an exploration plan, not a validated recommendation.

The benefit materializes only in saturated multi-instance serving with speculative decoding already in place, which exceeds the reader's single-GPU infrastructure, so this is a design to track rather than adopt.
Central equations
Original equations, typeset for reading. Paperraft explanations connect the mechanism, its aim, and the evidence.
Joint Training Objective. We train the model end-to-end with a composite objective that combines local generation quality with global structure prediction:

Feature Fusion Layer. Many speculative decoding methods rely only on the top-layer hidden states of the target LLM. These representations are often highly specialized for next-token prediction and may be less suitable for longer-horizon planning. Following Li et al. (2025), we therefore fuse hidden states from multiple depths to recover richer contextual signals for both drafting and length prediction. Let denote the hidden states of the frozen target LLM with layers. We select a subset of layers , corresponding roughly to shallow lexical features, intermediate syntactic patterns, and deeper semantic abstractions. These representations are concatenated and projected into the draft embedding space :

Draft Model Head. The first branch follows the standard speculative decoding setup. It maps the draft decoder state at step to the vocabulary space to approximate the target model’s next-token distribution:

Claims and evidence

- claim 01Paperraft inference
Read the brief interpretation
OUTLETS replaces external proxy models and shallow state probes for output-length prediction with a lightweight regression head on representations already computed by an EAGLE-3-style speculative decoding draft model. Its cost is minimal at inference only if speculative decoding is already deployed; otherwise it requires training and serving a draft backbone plus the regression head, which negates the claimed efficiency. It can fail if the serving stack lacks speculative decoding, if request volume never saturates the scheduler (where length-aware scheduling yields nothing), or if length distributions drift from the training distribution, degrading prediction fidelity.
This is a Paperraft inference. It is not pinned to a verified PDF passage.
Inspect the source - claim 02Paperraft inference
Lower MAE than evaluated length-prediction baselines; under saturated disaggregated serving, scheduling with OUTLETS predictions reduces short-request P99 latency by 34.8%.
