GPT-5.6 and Gemini 3.5 Pro Reportedly Delayed to July Release, OpenAI’s New Voice Model May Launch This Week

Tech blogger @synthwavedd has stated that several highly anticipated cutting-edge AI models have adjusted their release schedules. Among them, GPT-5.6, originally slated for a near-term release, has been postponed to mid-July, while Google DeepMind has canceled the planned late-June launch of Gemini 3.5 Pro due to dissatisfaction with the model’s current performance.

Meanwhile, preparations for the launch of OpenAI’s new-generation bidirectional voice model, Bidi, are progressing on the ChatGPT platform, with availability to users potentially coming as early as this week. Reports indicate that Bidi supports full-duplex voice interaction, allowing users to speak simultaneously with the model and interrupt the conversation at any time, marking a significant upgrade over existing voice modes.

Additionally, Anthropic has granted early access to its Claude Sonnet 5 model for select enterprise clients. As the release progress of flagship models Mythos 5 and Fable 5 has slowed, Claude Sonnet 5 is seen as an interim product solution for Anthropic to alleviate competitive pressure.
