GPT-7 leaks: Codenamed "Bel" - OpenAI's next flagship model is codenamed Bel, mosttly GPT-6.5 or GPT-7 - In a recent post, OpenAI revealed that a model escaped its isolated training environment through a DNS misconfiguration, forcing a pause in frontier training - Training resumed on October 1 after security improvements, which are likely part of Bel's development - The more powerful these models become, the more security they need. Even isolated environments aren't enough when models find ways to escape them - Remember Anthropic's Mythos? Many people initially thought the security concerns were just IPO hype, but now we are seeing similar concerns with Bel - OpenAI is reserving substantial compute for continuous security testing, which can affect Bel's launch timeline Bel is expected to have 10T+ parameters and can arrive by the end of this year, but these security challenges may delay its release

Gemini 4 Carbon leaks: Coming next month - Gemini 4 Carbon is in internal testing on Antigravity at the Teamfood stage - Teamfood is basically the phase where a new model is made available to selected employees to use and provide feedback - If the feedback is good, they expand testing to more employees. From what I'm seeing, the feedback seems good, so we can see a launch as early as the first week of next month - After Teamfood comes Dogfood, with wider employee testing, followed by security checks, benchmarks, external partners, and finally the launch if everything goes well - I'm using this model in Arena, and it feels easily comparable to Opus 5.5. Excited for this one, tbh

Gemini 4 Carbon: Kintsugi Vase output. I asked it to build an 3D Kintsugi Vase that breaks apart and reassembles with golden cracks. It did a really good job. I would say Carbon is comparable to Opus 5.5 here, unlike Kimi K3.1 Pro. Overall, I'm really liking Carbon's design taste so far.
