Brief

OpenAI is treating the user interface as a core product choice: @modernmarket_ quotes @Legendaryy saying the company is testing interaction methods — ChatGPT Voice, a specialized keyboard with voice control, picking the most responsive model, and the ChatGPT app (formerly Codex) — to discover the best way for humans to work with LLMs.

Why it matters

On 2026-07-24, @modernmarket_ quoted @Legendaryy asserting OpenAI’s biggest product decision may be how humans communicate with models, not the model itself.

Key details

  • OpenAI is experimenting with interaction methods — ChatGPT Voice, a specialized keyboard (including voice control), choosing the most responsive model, and the ChatGPT app (formerly the Codex app) as a 'harness' for use.
Source evidence

OpenAI’s biggest product decision may not be the model. It may be how humans communicate with it.

@Legendaryy on ChatGPT Voice: "And for me, it’s saying that they’re experimenting at the same time with: What is the best way to use an LLM?

What’s the best way to communicate with it? Is it to have a specialized keyboard, which also has voice control, by the way?

Is it to have the most responsive model? They, of course, also have their own harness, the ChatGPT app, which used to be the Codex app.

So it seems like this question of what the best way is to work with your AI isn’t fully clear yet.”
