🤝 Google Joins Forces with Giants to Launch A2A Protocol, Ushering in a New Era of AI Agent Collaboration

At its Cloud Next 2025 conference, Google officially launched the Agent2Agent (A2A) open interoperability protocol, aiming to break down barriers between different AI agents and enable secure, efficient cross-platform collaboration among agents built by different developers using various frameworks. The protocol has garnered support from over 50 industry giants, including Salesforce, SAP, and Atlassian, signaling the rapid formation of an interconnected, collaborative enterprise AI agent ecosystem.

Core Highlights

  1. Cross-Boundary Communication: A2A builds upon existing standards (like HTTP, SSE, JSON-RPC), providing a common framework for agents from diverse vendors and architectures to securely exchange info, discover capabilities, and coordinate actions, even without shared memory or tools. It natively supports multiple modalities like text, audio, and video.
  2. Protocol Complementarity: A2A complements, rather than replaces, Anthropic’s Model Context Protocol (MCP). Think of MCP as the “wrench” empowering a single agent, while A2A is the mechanism for multiple agents (a “mechanic team”) to collaborate on problem-solving, together building a more robust autonomous agent ecosystem.
  3. Ecosystem Co-Construction: Google collaborated with numerous tech partners and service providers on A2A’s design and implementation. Released under the Apache 2.0 license, its open, collaborative approach aims to establish it as an industry standard and foster a thriving ecosystem.
  4. Empowering Complexity: A2A excels in enterprise processes requiring multi-agent collaboration, like automated recruitment. Built-in features like capability discovery (Agent Card), task flow management, and UX negotiation significantly boost automation and efficiency for complex tasks.

Value Proposition

  • For Professionals: Lowers the barrier to building complex AI applications; developers can easily integrate specialized agents from different vendors, reducing costs. Enterprises can connect siloed systems for deeper automation and efficiency. The open protocol will also spur new agent services and business models.
  • For Ordinary People: Users may experience more seamless, intelligent services. For complex travel booking, interacting with one primary agent could trigger background collaboration among specialized agents via A2A, simplifying the process. Personal/work assistants will become more powerful, leveraging multiple agents for comprehensive, personalized services.

🧠 OpenAI Fully Upgrades ChatGPT Memory, Altman Hints GPT-4.1/o3/o4-mini Are Coming Soon

OpenAI CEO Sam Altman announced a major upgrade to ChatGPT’s Memory feature; it can now reference all past conversations to provide more personalized and coherent service. Altman believes long-term user understanding is key. The feature rolls out first to Plus/Pro subscribers. Concurrently, Altman confirmed o3 and o4-mini models are coming soon, while reports suggest GPT-4.1 and its mini/nano versions might debut as early as next week.

Core Highlights

  1. Memory Evolution: The core upgrade expands memory scope. A new “Reference chat history” option lets ChatGPT automatically learn from all past dialogues, building a comprehensive user profile to understand preferences, style, and context for more natural interactions.
  2. New Model Signals: Altman’s teaser for o3/o4-mini, combined with media reports on the imminent GPT-4.1 series (main, mini, nano) and code evidence, strongly suggests OpenAI is preparing a suite of new models spanning flagship upgrades to cost-effective and specialized (e.g., reasoning) options.
  3. Personalization Push: Altman sees enhanced memory as key to deep AI personalization, envisioning AI that “knows you over your life.” This highlights OpenAI’s strategy to shift AI from a general tool to a personalized companion, focusing on long-term user relationships.
  4. User Control: Addressing privacy concerns, OpenAI emphasizes user control. Users can disable “Reference chat history” or turn off Memory entirely, tell/correct AI’s memory, and use “Temporary chat” mode which isn’t saved to memory.
  5. Industry Race: Enhanced memory and personalization are new battlegrounds for top AI firms. Google Gemini and Microsoft Copilot recently introduced similar features, indicating a consensus on using personalized experiences to boost user stickiness and differentiation.

Value Proposition

  • For Professionals: Highlights personalization’s role in building competitive AI moats. AI that learns user preferences gains higher stickiness. Developers need to focus more on leveraging user data and long-term interaction value. Combined with lightweight models, this could enable personalized AI in more resource-constrained scenarios, while intensifying the challenge of balancing utility and privacy.
  • For Ordinary People: A ChatGPT with better memory means smoother, more efficient interactions without repeating context or preferences. AI can offer more tailored help. However, more extensive personal data collection increases privacy risks, requiring users to manage settings carefully. Over-personalization might also lead to filter bubbles.

🔒 Breakthrough in Mobile AI Model Security: THEMIS Framework Achieves Efficient Watermarking Protection

Addressing the risk of illicit extraction and theft of on-device AI models, a joint research team from several universities proposed the THEMIS framework – the first systematic solution designed specifically to protect the Intellectual Property (IP) of post-deployment mobile AI models. By embedding hard-to-remove digital watermarks, it helps developers track and prove ownership, effectively combating model theft. The research has been accepted by the top-tier security conference USENIX Security 2025.

Core Highlights

  1. Targeting Pain Points: THEMIS tackles three core challenges in mobile AI model protection: ① Encryption & Metadata Loss: Analyzes encrypted model behavior via dynamic execution tracing to recover missing metadata; ② Read-Only Limitation: Introduces innovative “Model Rooting” to parse model schema and generate code, rebuilding a writable copy; ③ Inference-Only Nature: Proposes the novel FFKEW training-free watermarking algorithm, embedding robust watermarks efficiently via a single forward pass.
  2. Innovative Solution: THEMIS is an automated toolchain integrating multiple novel methods: reverse engineering, runtime analysis, model format parsing/code generation, and the FFKEW algorithm, designed for ease of use.
  3. Proven Effectiveness: Tested on 403 real-world Android apps with local AI models from Google Play. Successfully watermarked models in 327 apps (81.14% success rate) with minimal impact on model accuracy (average drop < 2%), proving practical robustness.
  4. IP Guardian: Offers an automated, out-of-the-box solution for developers lacking extensive AI security resources to protect their core AI model assets from copying and misuse, safeguarding their IP and market competitiveness.

Value Proposition

  • For Professionals: Provides an unprecedented, effective technical safeguard for companies deploying AI models on mobile (e.g., in healthcare, finance). Helps protect R&D investment, enforce IP, deter piracy, and secure business interests. The automated tool lowers the barrier to implementing advanced model protection. Long-term, effective IP protection incentivizes innovation and fosters a healthier mobile AI ecosystem.
  • For Ordinary People: While users don’t directly see watermarks, a more secure mobile AI ecosystem benefits them. Protected developer IP encourages continuous R&D, leading to higher-quality, trustworthy apps. Such research also advances overall AI security technology, enhancing digital safety.
