OpenAI announces new models
OpenAI has announced that GPT-5.6 Sol, as well as Terra and Luna, will be presented this Thursday.
OpenAI has already begun to gradually expand early access for users worldwide, so some may already notice new models in the Codex interface.
P.S.
Alongside GPT-5.6, a new voice model from OpenAI may also be released, which looks very promising. It operates in a bidi (bidirectional interaction) mode, which is exactly what everyone expected from the voice model last time.
Why it matters
AnalysisThis is important as the new OpenAI models could significantly enhance artificial intelligence capabilities and user interaction. The announcement of a new voice model also opens up new prospects for interactive technologies.
