Users can transform product display images into 360-degree rotation animations or quickly generate complete short films from storyboard sketches.

5️⃣ Tesla Launches Grok AI Assistant: Supports Only AMD Ryzen Processor Users

Tesla has launched the Grok AI assistant aimed at enhancing driving experience, but it is only applicable to vehicle models equipped with AMD Ryzen processors. The assistant currently has limited functionality but will gradually expand capabilities through future software updates.

System Requirements:

Hardware Limitation: Grok AI assistant only supports Tesla models equipped with AMD Ryzen processors
Hardware Verification: Users need to confirm system hardware in Settings to use Grok functionality
Future Expansion: Grok will continuously expand its functions and applications through future software updates

Available through the 2025.26 software update, Grok requires Premium Connectivity or Wi-Fi and is currently US-only. The assistant focuses on user interaction but cannot directly control vehicle navigation or air conditioning functions, with Tesla gradually switching to AMD's Ryzen embedded platform since 2021 for enhanced computing performance.

6️⃣ OpenAI Delays Open-Source Model Release, Prioritizes Safety Testing

OpenAI has delayed the release of its open-source large model primarily due to requiring more time for safety testing. Sam Altman emphasizes that once model weights are released, they cannot be recalled, making safety assurance the top priority. Despite disappointment over the delay, users generally understand and recognize this decision.

Release Considerations:

Indefinite Delay: OpenAI announced delay of open-source large model release due to need for additional safety testing
Irreversible Release: Sam Altman emphasizes that models cannot be recalled after release, making safety assurance the primary task
Community Understanding: Users express understanding about this delay, recognizing the importance of safety testing

The delay affects the highly anticipated first open model release from OpenAI in years, expected to have reasoning capabilities similar to the o-series models. The decision reflects OpenAI's commitment to responsible AI deployment, with the company stating they need time to review high-risk areas before public release.

7️⃣ Liquid AI Major Open Source LFM2: Edge AI New Champion with Speed and Efficiency Breakthrough

Liquid AI has open-sourced its next-generation Liquid Foundation Models (LFM2), optimized specifically for edge devices and setting new standards in speed, energy efficiency, and performance.
