AWS Bedrock Llama 3.3 Fine-Tuning: Region Limits and Cost Insights
An AWS developer conducted a comprehensive sweep of all 33 Bedrock regions to identify where Llama 3.3 70B fine-tuning is available. The findings reveal that only us-west-2 supports native fine-tuning for this model, while us-east-1 only offers Amazon's own models. The article also highlights a pricing transparency issue: AWS publishes training prices for Llama 2 but not for Llama 3.3, despite the capability being available. The author details the undocumented distinction between queued and actively training jobs, showing that queue time is free, and advises against creating arbitrary wait thresholds. Custom Model Import is presented as a potential alternative for EU residency, though the author's attempt failed with a generic error. The article provides practical guidance on checking job status details, understanding schema differences between model versions, and managing quotas and storage costs.
Provides critical operational insights for AWS Bedrock users, highlighting regional limitations and cost-saving opportunities for fine-tuning large language models, which is directly relevant to AI-driven advertising and marketing technology.

Fine-tuning Llama 3.2 3B for Medical QA
A developer documents Week 1 of a project to fine-tune Llama 3.2 3B Instruct for medical question-answering. The post describes the motivation (general-purpose LLMs can be clinically unreliable), choice of base model (meta-llama/Llama-3.2-3B-Instruct) and dataset (MedQuAD via lavita/medical-qa-datasets on Hugging Face), and the end-to-end stack: training on Google Colab (NVIDIA T4, 15.8GB VRAM) with 4-bit quantization (bitsandbytes/QLoRA and LoRA), hosting checkpoints on Hugging Face Hub, and serving inference via a Dockerised FastAPI endpoint. The author shows baseline inference examples (including a documented factual error about diabetes) and lists next steps (data preparation and supervised fine-tuning using MedQuAD). A public GitHub repo is linked for reproducibility.
Optimize Machine Learning Models on AWS
This technical guide explains how to optimize machine learning models on AWS across three pillars: model accuracy, inference latency, and infrastructure cost. It covers SageMaker Automatic Model Tuning (Bayesian hyperparameter search), SageMaker Neo for hardware-specific compilation (claims up to 2× speedups and reduced memory footprint), and Deep Learning Containers plus Amazon Elastic Inference for lower-latency GPU access. The article describes cost-saving patterns such as SageMaker Multi-Model Endpoints (MME) to host many models on a single instance, and model-level techniques like quantization and pruning—highlighting AWS Inferentia and Trainium as purpose-built silicon for efficient inference. It also recommends using the SageMaker Inference Recommender to benchmark instance types (throughput, latency, cost per inference) and select the most cost-effective deployment.
Benchmarking LLMs with AWS Labs' LLMeter
This article is a practical guide to using AWS Labs' LLMeter, a Python-based benchmarking library for large language models. It explains the key performance metrics LLMeter captures—Time to First Token (TTFT), Tokens Per Second (TPS), Time to Last Token (TTL), and Cost Per Request—and shows how to configure experiments, endpoints, and cost models. LLMeter targets modern Python (3.10+), leverages asyncio for concurrent client simulations, and recommends streaming endpoints for accurate latency measurement. The guide covers multi-client load testing, Plotly-based interactive HTML visualizations, and a minimal live dashboard the author built for real-time monitoring. The article links to the LLMeter GitHub, a QAInsights dashboard script, and a video walkthrough for hands-on replication.
