Rumor: GPT-6 family to include sol, tera and luna
A leak claims GPT-6 sol is more token-efficient, faster at cognitive tasks, less prone to hallucinations and less likely to hit limits than Astra, and that Tibo has denied the models would only launch at the September 28 DevDay.

this all but confirms we're getting the gpt-6 family: sol, tera and luna. yesterday, some sources claimed the models wouldn't drop until devday on sept. 28, but tibo has basically debunked that. gpt-6 sol should be: - cheaper per task (token efficient) - faster at cognitive tasks - less prone to hallucinations - less likely to hit limits than astra still no sign of opus 5.2 from anthropic. i guess "pace the frontier" was just a facade.
