RESUMEN

En 30 segundos

Matthew Berman demonstrates how to expose the Max reasoning-effort option in the settings interface shown in his August 2026 video, then select it for Luna. He also expresses a negative personal view of Ultra and cites an 80% Luna discount. The clip does not provide a benchmark or details establishing the discount’s scope, and settings, model support and promotions can change.

  1. 1A reason to use LunaBerman cites an 80% discount, but the short clip does not specify its terms or duration.
  2. 2Expose Max in settingsHe opens configuration and enables Max under available reasoning efforts; the menu notes that availability varies by model.
  3. 3An opinion about UltraHe advises turning Ultra off based on his own assessment, without presenting a controlled test.
  4. 4Select LunaHe returns to the model picker and selects Luna with Max available.

Conclusiones

  1. The demonstrated configuration menu lets users choose which reasoning-effort levels appear in model controls.
  2. Berman enables Max and then selects Luna in the model picker.
  3. Available reasoning efforts depend on the model and the product version.
  4. His criticism of Ultra and mention of an 80% discount are time-specific claims, not independently verified results.

Reasoning effort configuration

Berman cites a Luna discount and shows the available reasoning-effort settings. He enables Max and offers his opinion of Ultra.

I want to use Luna more and say it is 80% off in this August 2026 video. The clip does not explain the promotion’s scope or duration, so the discount should be treated as a time-specific claim rather than a current price. My focus is the Max reasoning-effort option, which I say is not enabled by default in the setup shown.

Available reasoning efforts
DIAPOSITIVA 1 / 2Available reasoning effortsThe demonstrated settings menu lists selectable effort levels and notes that model availability varies.

In the demonstrated settings interface, I open Configuration and find “Available reasoning efforts.” I enable Max so it can appear in model controls. The menu says availability varies by model; I also mention Terra and Sol, but supported choices can change by version and model.

I recommend turning Ultra off because I believe it uses too many tokens without enough benefit in my experience. That is my assessment, and this short clip provides no controlled comparison or evidence that Ultra is generally broken. After changing the settings, I select Luna and show that Max is available.

Selecting Luna

He selects Luna after exposing Max. The clip does not independently validate the discount or compare reasoning settings.

Selecting a model
DIAPOSITIVA 2 / 2Selecting a modelThe picker shows the model choices in the historical interface.
