Meta and Google release new AI models

Meta and Google have released new AI models as part of a busy September launch cycle, according to The Rundown AI. Meta introduced Muse Spark 1.3, while Google launched Gemini 3.8 Flash, which the newsletter says shows improved results in coding, reasoning, and agent tasks. The report says Meta is emphasizing a strong mix of performance and lower cost, while Google is trying to regain momentum after a difficult year. The piece also notes that Google’s leadership described Gemini as still below the frontier, suggesting the company is continuing to push for stronger model performance. The newsletter also highlighted an OpenAI report about a new model technique that may improve coding and computer use, but could make reasoning harder to monitor. In addition, it included educational segments on tech literacy, job interviews, and AI workflows.
