Guide: Deploy ML Model to AWS SageMaker
A step-by-step tutorial published on dev.to (2026-06-22) explains how to deploy a trained machine-learning model to AWS SageMaker. The guide covers saving a scikit-learn model with joblib, creating a requirements.txt, uploading model and dependencies to an S3 bucket, writing a SageMaker-compatible inference.py with model_fn/input_fn/predict_fn/output_fn, deploying the model using sagemaker.sklearn.SKLearnModel, testing the realtime endpoint via boto3's sagemaker-runtime, and cleaning up resources. The post includes common error causes and fixes, required IAM permissions, and a simple cost estimate for an ml.m5.large instance and S3 storage.
Practical how-to content for deploying ML models; useful to practitioners but not industry-shifting or a major platform policy/technical release.

Key Takeaways & Evidence Grounding
- Tutorial published on dev.to on 2026-06-22 teaches deploying ML models to AWS SageMaker.
- Author demonstrates saving a trained model using joblib.dump('model.pkl') and bundling a requirements.txt.
- Model and requirements are uploaded to an S3 bucket (example path s3://<bucket>/models/model.pkl) using boto3.
- Provides a SageMaker inference.py implementing model_fn, input_fn, predict_fn and output_fn for realtime endpoints.
- Shows deployment via sagemaker.sklearn.SKLearnModel.deploy to create an endpoint (example uses ml.m5.large); estimates ml.m5.large ≈ $0.20/hour and S3 ≈ $0.02/GB/month.

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.
Deploy SageMaker Real-Time Endpoints with Terraform
This technical tutorial shows how to deploy Amazon SageMaker real‑time inference endpoints to production using Terraform. It describes a three‑layer architecture (Model, Endpoint Configuration, Endpoint) and provides concrete Terraform examples: IAM roles, aws_sagemaker_model, aws_sagemaker_endpoint_configuration, and aws_sagemaker_endpoint resources. The post covers blue/green canary deployments with automatic rollback driven by CloudWatch alarms, autoscaling via App Auto Scaling and the SageMakerVariantInvocationsPerInstance metric, monitoring alarms for errors and latency, and environment-specific tfvars for dev/prod. Operational tips include using create_before_destroy for endpoint configs, pinning container tags, load testing autoscaling targets, and considering serverless inference for very low traffic workloads.
Run Large Language Models Locally with LM Studio
The article is a practical guide explaining how individuals and small teams can run large language models (LLMs) locally using tools such as LM Studio and Ollama. It highlights independent researcher Benjamin Marie and his blogs (The Kaitchup and The Salt) as sources of hands-on tutorials and notebooks. The piece walks through installing LM Studio, basic memory calculations for model sizes, choosing trustworthy GGUF builds and compression levels, sanity-checking model outputs, and trade-offs where more capable “thinking” models can be slower. It aims to give readers enough intuition to select models and troubleshoot common performance and correctness issues without needing to become deep ML engineers.
