Our Own Jev: Typed Decisions in One Forward Pass, from an In-House Judge to Open LoRA Models

Yuchuan Weng, Chi Liu, Xin Chen +1

A typed decision maps evidence, a question and a fixed set of options to a probability for every option, computed in one forward pass, by reading a language model's logits or a sma…

Student-Guided Teacher Distillation for Efficient LLM Task Routing: Positioning Against Jev-Style System-1 Classifiers

Haifeng Wu, Srinivasan Manoharan, Jian Wan +3

Zero-shot classifiers are useful for routing user requests to specialized LLM tasks, but scoring every request against a large candidate set is expensive: a zero-shot NLI classifie…

Zero-Trust Authorization and Discovery for Enterprise MCP

Huan Li, Yuwei Wang, Srinivasan Manoharan

LLM agents translate natural-language context, which may include attacker-controlled text, into privileged tool calls, so authorization must remain effective even when an agent is…

Task-to-Model Optimization for Enterprise LLM Coding Assistants: A Data-Driven Framework for Cost-Optimal Routing

Srinivasan Manoharan, Junhua Zhao, Fangbo Tu +6

Enterprise AI coding assistants incur substantial inference spend, and naive token-cost minimization often fails to reduce end-to-end cost once retries, escalations, and developer…

Hybrid Semantic Tool Discovery for Enterprise MCP Gateway: Architecture and Implementation

Olympia Saha, Amy Wang, Srinivasan Manoharan

Large language model (LLM) agents invoke external tools to retrieve and reason over information beyond pretrained knowledge. The Model Context Protocol (MCP) standardizes how such…

A Gateway Architecture for Enterprise MCP Authentication: Unifying Heterogeneous Auth, Identity Delegation, and the User / Non-User Persona Problem

Suraj Kumar, Amy Wang, Srinivasan Manoharan

The Model Context Protocol (MCP) has become the de-facto interface for connecting LLM agents to enterprise tools, and adoption has been explosive: within a year, large organization…

RLM-Cascade: Response-Level Speculative Decoding for Cost-Efficient LLM API Serving

Haifeng Wu, Srinivasan Manoharan, Fangbo Tu +2

We present RLM-Cascade, a proxy-layer system that applies speculative decoding at the response level to reduce LLM API costs without requiring model architecture access or a shared…

Domain-Adapted Small Language Models with Hybrid Post-Processing: Achieving Cost-Efficient, Low-Latency Multi-Label Structured Prediction via LoRA Fine-Tuning on Scarce Data

Srinivasan Manoharan, Dilipkumar Nallusamy, Sachin Kumar +1

Deploying frontier large language models (LLMs) for domain-specific structured evaluation tasks incurs prohibitive latency, cost, and data-privacy overhead. We present a hybrid fra…

Beyond Output Matching: Preserving Internal Geometry in NVFP4 LLM Distillation

Fangbo Tu, Junhua Zhao, Chi Liu +4

Demand for low-precision inference, including NVFP4-based approaches, has grown as large language models are increasingly deployed in latency and cost constrained production enviro…
