Machine Learning

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

The short version

  • Each has a real cost: NotebookLM requires Google account; no standalone access without Gmail or Google Workspace; 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.

  • Letting an analytics team test whether a predictive column has any business value before asking for data science headcountnot NotebookLM
  • Scoring rows inside a SQL pipeline where moving data out to a separate service would add fragility for little benefitnot NotebookLM
  • Organisations committed to AWS whose main constraint is a data science backlog rather than modelling sophisticationnot NotebookLM

Where each one falls short

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

NotebookLM

  • Requires Google account; no standalone access without Gmail or Google Workspace
  • Free tier details not published; unclear what features or usage limits apply
  • Upgrade options mentioned but not specified in available public documentation
  • Limited integrations outside Google Workspace ecosystem

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.

Questions people ask

Is NotebookLM or Amazon Redshift ML better?
Neither clearly leads. NotebookLM starts at Free and Amazon Redshift ML at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, NotebookLM or Amazon Redshift ML?
NotebookLM starts at Free and Amazon Redshift ML at Free.
Does NotebookLM or Amazon Redshift ML run on more platforms?
Both run on Web, so platform support will not decide this one for you.
Can I use NotebookLM for free?
Both have a free tier, so you can try either at no cost before committing.
What is NotebookLM best used for?
NotebookLM is most often used for research synthesis and document analysis for students and academics, knowledge extraction from large document sets for business intelligence, audio-based learning through generated overviews and lectures, grounded q&a over proprietary documents or repositories. Of those, research synthesis and document analysis for students and academics and knowledge extraction from large document sets for business intelligence are not what Amazon Redshift ML is typically brought in for.
What can NotebookLM do that Amazon Redshift ML cannot?
Amazon Redshift ML covers CREATE MODEL in SQL, Automatic model selection, Local inference, Bring your own model.

Answered from the vendors’ own pages

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.

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.

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.

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.
