DeepEdu-v1: Efficient and Scalable Agentic LLMs for Vietnamese Education

Researchers submitted DeepEdu-v1, an AI-tutoring system for Vietnamese education built on the SCALE (Self-improving Context-Aware Learning Engine) framework, to arXiv on 25 Sep 2026. In its deployed configuration, DeepEdu achieves a nearly x2 TTFT speedup over standard vLLM serving and lifts agentic accuracy from 70.0% to 79.5% on complex tasks, with the strongest per-track gains on financial-reasoning and interactive-agent benchmarks. The system's long-context inference engine issues x7.7 fewer retrieval calls than a state-of-the-art selective-attention baseline and cuts prefill latency (TTFT) by roughly 35% while matching or improving task accuracy, addressing data-sovereignty constraints such as Vietnam's Decree 53 and hallucination on region-specific material.

Cloud assistants such as ChatGPT route sensitive student data to foreign servers---violating data-sovereignty laws such as Vietnam's Decree 53---and, pre-trained on Western-centric corpora, are not organized around the national textbook curriculum, so their knowledge of local content is unsystematic and frequently hallucinated. Self-hosting an open model keeps data on-premise but hits a two-fold wall: post-training quantization AWQ, GPTQ tames the static weight footprint, yet the dynamic KV cache and prefill latency of long tutoring contexts still cause out-of-memory failures and slow responses on consumer GPUs, while the model keeps hallucinating on region-specific material. We present DeepEdu-v1, an AI-tutoring system for Vietnamese education built on SCALE Self-improving Context-Aware Learning Engine , a framework with two innovations. First, a long-context inference engine amortizes token selection from per-sub-chunk to per-cluster granularity; on long-context retrieval it issues x7.7 fewer retrieval calls than a state-of-the-art selective-attention baseline, cutting prefill latency TTFT by roughly 35% while matching or improving task accuracy. Second, a self-improving agentic layer continuously curates a verified playbook from past interactions instead of fine-tuning, a design intended to progressively reduce reliance on dominant-language priors as trustworthy local knowledge accumulates. In its deployed configuration, DeepEdu achieves a nearly x2 TTFT speedup over standard vLLM serving and lifts agentic accuracy from 70.0% to 79.5% on complex tasks, with the strongest per-track gains across financial-reasoning and interactive-agent benchmarks.
