Even the image models are not good enough world models yet, gpt-image-2 and nano banana make pretty obvious world model like mistakes. is way harder, so no hope of that anytime soon. Maybe with 2-3 OOMs it gets good enough, but that doesn't feel like a reasonable thing to

Technical challenges in zero-shot voice synthesis and audio quality
By
–
C’est pas possible d’avoir une voix de bonne qualité (ou de qualité équivalente) en sortie avec un enregistrement GSM compressé. Ça ne va pas ressortir une voix « de mauvaise qualité » : les approches zero-shot vont repartir de données qui ne sont pas entraînées sur des voix GSM

Critique of AI voice synthesis output quality

Et c’est censé prouver quoi ? Je ne comprends pas. Ce que tu démontres, c’est littéralement ce que j’écris dans mon post, non ? Tu as un enregistrement de haute qualité, et pourtant la voix en sortie est très loin d’être de bonne qualité. On est sur une voix monotone, qui plus

Fun fact, I saw a demo of this at an OpenAI event in London in something like October 2025 – over half a year ago. They told us that they trained the model on UN synchronised translators. Not sure why it took so long to release it https://t.co/lwoaaZy7eB

Most AI products are still one confident hallucination away from embarrassing your entire company.

Everyone wants “agents.”
Nobody wants to admit the real bottleneck is trust.
If Giga really got hallucinations down to ~1%, that’s not a feature.
