Continuous Diffusion Models Make a Comeback in 2025

Continuous diffusion models for language are experiencing a resurgence after years of dormancy. Modern language models are typically autoregressive, but diffusion models reverse a corruption process to generate sequences. In 2021, the first attempts to apply continuous diffusion to language involved replacing a continuous corruption process with a discrete one. By 2023, virtually all new research used discrete diffusion, but in 2025, continuous methods are back. Researchers are exploring the benefits of continuous diffusion, including its ability to represent uncertainty at the token level and a rich toolbox of sampling algorithms. The key question: can continuous diffusion models match or outperform autoregressive models in specific settings?

Agent Security Flaws Exposed in AI Gateways

In June, CISA added a LiteLLM flaw to its Known Exploited Vulnerabilities catalog after attackers abused it in the wild. The bug allowed command execution on the host through the gateway itself, chaining with a second flaw to require no credentials. Seven common vulnerabilities and exposures (CVEs) were disclosed in a single AI gateway in a month. This highlights the critical need for robust agent security controls, especially in brownfield scenarios where existing systems are integrated with new AI technologies. The control plane struggles to distinguish justified actions from operationally inappropriate ones, making enforcement challenging. Each control depends on context generated upstream, emphasizing the importance of attribution and delegation context.

Cloudflare Launches AI Search, Streamlining Data Retrieval

Cloudflare has launched AI Search, a built-in search and retrieval service designed to give AI agents and applications a ready-to-use search engine over custom data. This service simplifies data retrieval by automatically handling the end-to-end search pipeline, including crawling, ingestion, embedding, and retrieval. Developers can now index collections of structured or unstructured data and make them accessible to agents without the need for manual sitemaps. The service is available across several Cloudflare-managed services, including API and developer documentation, Astro, Vite, Hono, Replicate, and others. During the beta period, AI Search is free to use, making it an attractive option for developers looking to enhance their data retrieval capabilities.

Liux Big Electric Microcar Secures Europe-Wide Homologation

Liux, a Spanish startup, has secured Europe-wide homologation for its Liux Big electric microcar, set to hit the market in the first half of 2023. This marks a significant step for the company, which has grown to 65 employees and is ramping up production across three facilities in Spain. The Liux Big, designed to fit into tight urban spaces, is small enough to park at a right angle to the curb and comes with a 260-liter trunk. With a final price tag below €18,000, it aims to cater to city-dwelling second-car buyers, especially those aged 55-60 who have joined the waiting list. The company expects to reach a production capacity of 20,000 cars a year by 2030, making it a serious contender in the growing microcar market.

SpaceX Builds Secret Foundry for Gas Turbine Blades in Texas

SpaceX has secretly built a foundry in Bastrop, Texas, to cast gas turbine blades, a process that's crucial for accelerating natural gas turbine production. By doing this in-house, SpaceX can speed up production by up to 18 months, giving them a significant edge in the AI infrastructure market. The company has purchased 830 acres near its Starlink factory, indicating a major investment in this technology. The casting process is notoriously difficult, with only four companies worldwide mastering it at industrial scale. Each blade must be cast as a single crystal in a vacuum furnace, a feat that SpaceX is now attempting to replicate. This move could disrupt the current market dynamics, where GE Vernova is sold out through 2030 due to AI infrastructure demand.
