1. Kimi K3.1 Pro Retains the World's Largest Open-Source Model Title with 3 Trillion Parameters

Moonshot AIKimi K3.1 ProOpen Source

In the early hours of October 24, Moonshot AI officially released Kimi K3.1 Pro, which retains the title of the world's largest open-source model with 3 trillion (3T) parameters and supports a 1-million-token ultra-long context window.

  • Parameter scale reaches 3 trillion, surpassing all previous open-source models
  • Supports a 1-million-token context, well suited to long-document analysis and complex coding tasks
  • Coding agent capabilities have jumped dramatically, enabling autonomous completion of multi-step development tasks
  • Priced at only 1/5 of comparable products, offering highly competitive value
  • Moonshot AI has promised to release the model weights before November 4
Editor's note: The combination of 3 trillion parameters and a 1-million-token context puts Kimi K3.1 Pro at the head of the open-source field. Even more important is its pricing strategy: challenging rivals at one-fifth of the price shows that Chinese large models are shifting from a "parameter arms race" to a "cost-effectiveness deployment battle."

2. The First AI Film Wins the Dragon Seal, AI Filmmaking Enters the Theatrical Era

Multiple sources have confirmed that the first film whose visuals were entirely AI-generated has officially received the Dragon Seal (public screening license) from the China Film Administration, with all visuals and part of the audio generated by artificial intelligence.

  • This is the first fully AI-generated film to receive a public screening license in China and worldwide
  • It marks the formal move of AI filmmaking from experimental shorts into the era of feature-length theatrical films
  • The National Radio and Television Administration has removed nearly 13,000 AI-manipulated videos over the past nine months, while remaining open to compliant AI creation
  • Production costs for AI films are only 1/10 to 1/50 of traditional films
Industry significance: The granting of the Dragon Seal means regulators have given preliminary recognition to the quality and safety of AI-generated content, paving the way for the industrialization of AI filmmaking. More AI film projects are expected to apply for release over the next six months.

3. Block Launches the Full-Duplex Voice Model Dessa

Jack Dorsey's fintech company Block has launched the full-duplex voice model Dessa, achieving a genuinely natural conversation experience.

  • Supports full-duplex communication: users can interrupt the AI at any time without waiting
  • Features real-time emotion recognition, adjusting response strategies based on the speaker's tone
  • Latency reduced to the millisecond level, close to a human conversation
  • Main application scenarios: customer service, voice assistants and financial consulting

4. OpenAI Discloses the Habitat Storage Architecture Serving a Billion Users
