has only given us verbal evidence of a potential narrow, non-universal jailbreak, which essentially consists of asking the model to read a specific codebase and fix any software flaws. Our understanding is that one potential jailbreak was shared with the government. We have reviewed a report that we believe is the basis of the government's directive and validated that the level of capability displayed there is widely available from other models (including OpenAI’s GPT-5.5), and is used every day

Seed-TTS-Eval has three main problems. First, only Chinese and English are considered, which lacks linguistic diversity. Second, they rely on outdated models such as Whisper-Large for ASR. Thirdly, they only draw from Common Voice for English and DiDiSpeech for Chinese, both of which are read speech (with minimal

It reads the codebase with Code Intelligence and draws on the context around the issue, like the discussions and affected customers. The agent can also connect to your team’s other tools like Sentry or Datadog to triangulate the problem. With a grasp of what to do, and the confidence there is a fix, the agent can open a coding session in the cloud, write a fix, open a
