GPT-3.5

Here's a sentence in a made-up language called "Xyzian": "Ftriz prah frtorg blix." Pronunciation: /f-t-r-i-z pr-ah fr-t-o-r-g b--i-x/ Translation: "The red flower blooms."

GPT-6 Astra

Made-up language: Velari

“Luma sei navora.”
Meaning: “The moon sings to the sea.”

Pronunciation: LOO-mah say nah-VOR-ah

  • Luma (LOO-mah) — “the moon”
  • Sei (say) — “sings to”
  • Navora (nah-VOR-ah) — “the sea”

In this invented language, sei describes a gentle, melodic call—so the sentence imagines moonlight as a song reaching across the water.

GPT-3.5’s pronunciation guide doesn’t actually guide anything. “/f-t-r-i-z pr-ah fr-t-o-r-g b–i-x/” just respells the words with hyphens between letters, so a reader still has no idea how to say “frtorg” aloud. It also skips the “explain it” part of the request: we get a translation, “The red flower blooms,” but no clue which word means red or flower.

Astra does what was asked. It gives stressed syllables (“nah-VOR-ah”), a word-by-word gloss, and a short note that sei implies “a gentle, melodic call.” Saying it aloud is effortless. In fairness, GPT-3.5’s consonant pileups like “Ftriz” sound more genuinely alien, while “Luma sei navora” is the soft, vowel-heavy style of a thousand fantasy novels, with “Luma” for moon being almost a cliché. Astra’s language is less surprising, but it is the only one of the two you could actually pronounce and understand.

From December 2022 to March 2023, visitors to LearnGPT, the earlier version of Emergent Mind, shared ChatGPT conversations they found useful or funny. On October 19, 2026, each prompt went to GPT-6 Astra exactly as it was shared: one message, no system prompt, default reasoning effort. Claude Opus 5.5 wrote the analysis under each pair after reading both answers. Original answers appear as the people who shared them pasted them. A few examples are left out because they depended on missing context or weren't appropriate to republish.
