Machine Learning

SQL statements in Redshift that train models on SageMaker and return them as functions

The short version

  • Each has a real cost: Aider requires comfort working in a terminal rather than a graphical IDE; Amazon Redshift ML training is billed by SageMaker separately from Redshift, so a feature that looks like a free SQL statement produces a second line item on a different part of the bill that the analyst who ran it usually cannot see.
  • They diverge on capability: Aider covers Multi-LLM support, Amazon Redshift ML covers CREATE MODEL in SQL.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Aider

  • Editing an existing codebase from the terminalnot Amazon Redshift ML
  • Pairing with an LLM on a new projectnot Amazon Redshift ML
  • Automating git-committed code changesnot Amazon Redshift ML
  • Working across many programming languagesnot Amazon Redshift ML
  • Bringing your own LLM API key to a coding workflownot Amazon Redshift ML

Amazon Redshift ML

  • Adding a churn or propensity score to an existing dashboard where the data is already in Redshift and nobody needs a bespoke modelnot Aider
  • Letting an analytics team test whether a predictive column has any business value before asking for data science headcountnot Aider
  • Scoring rows inside a SQL pipeline where moving data out to a separate service would add fragility for little benefitnot Aider
  • Organisations committed to AWS whose main constraint is a data science backlog rather than modelling sophisticationnot Aider

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Amazon Redshift ML

  • Training is billed by SageMaker separately from Redshift, so a feature that looks like a free SQL statement produces a second line item on a different part of the bill that the analyst who ran it usually cannot see.
  • Autopilot searches many candidate models by default and the duration and cost of CREATE MODEL scale with the data size and the MAX_CELLS setting, so an unconstrained statement against a large table is an expensive accident rather than an experiment.
  • Local inference runs on the Redshift cluster itself, so scoring millions of rows competes for the resources the warehouse exists to provide, and the remote inference alternative adds a per-batch network call plus an hourly SageMaker endpoint charge that persists whether or not anyone queries it.
  • The supported problem types are limited to what the exposed algorithms cover, so anything involving text, images, sequences, a custom loss function or a bespoke evaluation metric is out of scope and has to be built conventionally.
  • There is no retraining schedule, drift detection or model registry, so a model created by a statement stays exactly as trained until somebody remembers to recreate it, and nothing in the warehouse will report that its accuracy has decayed.

Answered from the vendors’ own pages

Aider: Is Aider free to use?

Aider itself is free and open source, released under the Apache 2.0 license. Users must separately supply and pay for API access to the LLM they choose to use with it.

Source
Amazon Redshift ML: Does it require SageMaker?

Yes. Redshift ML is an interface; the training happens in SageMaker and needs an IAM role and an S3 bucket for the intermediate data.

Aider: Which LLMs can I use with Aider?

Aider connects to OpenAI, Anthropic, Gemini, GROQ, DeepSeek, Ollama, Azure, Cohere, xAI, GitHub Copilot, Vertex AI, Amazon Bedrock, OpenRouter and most other LLM providers via API keys.

Source
Amazon Redshift ML: Is there an extra charge?

The SQL interface is part of Redshift, but the training runs as a SageMaker job charged at SageMaker rates, and a remote inference endpoint is billed for as long as it exists.

Aider: Can I use Aider for free without paying for an LLM API?

Yes, Aider can be used at no cost through OpenRouter's free model access (subject to daily usage limits) or Google's Gemini 2.5 Pro Exp, which the docs note performs well without a paid API key.

Source
Amazon Redshift ML: What kinds of model can it build?

Regression, binary and multiclass classification through the automatic path, plus direct use of XGBoost, linear learner, multilayer perceptron and K-means. Anything beyond structured tabular prediction is out of scope.

Aider: How does Aider handle version control?

Aider automatically stages and commits each change it makes to a connected git repository, generating a descriptive commit message for every edit so changes stay reviewable and reversible.

Source
Amazon Redshift ML: Can I use a model I trained myself?

Yes, through the bring-your-own-model path, either compiled into the cluster for local inference or called as a remote SageMaker endpoint.

Amazon Redshift ML: Does it retrain automatically?

No. Retraining means running CREATE MODEL again, on a schedule you build yourself, and nothing in the product monitors whether it is needed.
