Rumours from the leak trackers: Gemini 4 'Carbon', a new Google image model and Qwen 4

@Mr_Salio spotted a Gemini 4 'Carbon' model with 3D output being tested on Arena, Google testing a new image model under a Nano Banana 2.1 label, and a Qwen 4 checkpoint. @testingcatalog's daily brief adds Cohere's Model Vault in public beta, 4K output from Seedance 2.5 for enterprise customers, and a report that Thariq Shihipar has left Anthropic. None of this is officially announced, so treat it as reports.

Why it mattersNothing to act on yet, but a Gemini that outputs 3D would matter if you make product or event visuals. Wait for the official launch before you test it.

How we knowCompany figures are labelled as their own claims; anything we couldn't verify is labelled as a report or a claim.
