Facebook stands as the biggest social networking platform globally. We develop technologies that enable individuals to engage with their friends and family, discover communities, and expand their businesses. Inspired by the remarkable ways in which people support one another during challenging times, we see examples ranging from fundraising efforts to lifesaving assistance shared in posts or through blood donation sign-ups. The Facebook app simplifies the process of connecting with loved ones and finding new acquaintances, thanks to features such as Groups, Watch, and Marketplace that cater to shared interests. These tools not only foster personal connections but also create opportunities for communal growth and support.

X (formerly Twitter) is a global social media and communications platform where individuals, creators, brands, journalists, and organizations publish content, participate in conversations, and engage with audiences in real time. The platform supports short-form posts, long-form articles, photos, videos, live streaming, audio Spaces, direct messaging, and community discussions that allow users to communicate across a wide variety of topics. X has expanded beyond traditional social networking by introducing AI-powered capabilities through Grok, creator monetization programs, premium subscription tiers, enhanced analytics, and advanced publishing features for eligible users. Businesses use X to engage customers, provide support, advertise products and services, monitor trends, and build brand awareness through public conversations. Premium subscribers gain access to additional capabilities such as longer posts, expanded media uploads, verification features, and creator-focused tools that support audience growth and monetization. The platform also provides advertising products, business profiles, developer APIs, and engagement tools for organizations of different sizes. X is available through web browsers and mobile applications, allowing users to stay connected from virtually anywhere. Its combination of real-time communication, AI integration, multimedia publishing, and creator tools makes it useful for personal communication, news discovery, professional networking, and business engagement. By bringing together conversations, content creation, AI, and community interaction, X continues to evolve beyond its origins as Twitter into a broader communications platform.

Claude Opus 4.8 is Anthropic’s newest flagship AI model built to improve coding performance, reasoning accuracy, agentic task execution, and collaborative AI workflows for developers, enterprises, and advanced productivity use cases. The model serves as an upgrade to Claude Opus 4.7, delivering measurable improvements across benchmarks related to coding, practical reasoning, software engineering, and autonomous task management while maintaining the same pricing structure for standard usage. One of the most significant improvements in Claude Opus 4.8 is its enhanced honesty and judgment during complex tasks, reducing the likelihood of unsupported claims, hidden errors, or overlooked flaws in generated code and analytical outputs. Anthropic’s evaluations show that Opus 4.8 is substantially less likely than previous versions to allow software defects or reasoning mistakes to pass without flagging uncertainty or requesting clarification. The platform introduces new effort control settings that allow users to adjust how deeply the model reasons through tasks, balancing response quality, processing depth, speed, and token usage depending on workflow requirements. Claude Opus 4.8 also powers new dynamic workflow functionality in Claude Code, enabling the model to coordinate hundreds of parallel subagents within a single session to handle large-scale software engineering tasks such as codebase migrations and extensive automation projects. The model supports high-speed fast mode processing, now significantly more affordable than previous versions, while also offering higher-effort reasoning modes optimized for difficult coding and operational workflows.

Claude Fable 5 is Anthropic’s most capable generally available AI model, built to tackle demanding tasks across software development, research, business analysis, scientific exploration, and enterprise productivity. The model demonstrates state-of-the-art performance in coding, reasoning, visual understanding, long-context processing, and autonomous task execution. Claude Fable 5 can analyze large codebases, interpret complex documents and datasets, generate detailed reports, and assist with advanced decision-making processes. Its enhanced memory capabilities allow it to remain effective during long-running workflows and multi-step projects. The model also delivers strong performance in image analysis, chart interpretation, scientific reasoning, and technical problem-solving. Anthropic has incorporated advanced safety classifiers that detect certain high-risk topics and automatically redirect those interactions to a more restricted model experience. These safeguards are designed to reduce misuse while still providing productive assistance for legitimate users. Claude Fable 5 is available through the Claude platform and API, enabling developers and organizations to integrate advanced AI capabilities into their applications and workflows. The platform is designed to help businesses improve productivity, accelerate innovation, and streamline complex knowledge work.

Velt is a comprehensive SDK designed for collaboration that allows developers to seamlessly integrate advanced, real-time, and asynchronous collaboration functionalities into their web applications with ease. By utilizing Velt, developers can implement contextual comments similar to those found in Figma or Google Docs, indicators for live presence, collaborative editing capabilities, “follow me” viewing options, and audio/video screen sharing huddles akin to those used in Slack or Google Meet. Furthermore, Velt features a built-in recording function, reminiscent of Loom, which captures screen, camera, or audio content, along with AI-driven transcription and automatic summarization, enabling users to provide video or voice feedback and easily navigate to specific sections later. The platform also includes various collaboration enhancements like in-app notifications, user mentions, reactions, annotation tools such as arrows and highlights, analytics dashboards for monitoring user engagement, and customizable UI components that can be styled to align with the branding of any application. Velt takes care of all the intricate details, including real-time synchronization, conflict resolution through CRDTs, offline capabilities, scalability, and the option for self-hosting, ensuring a smooth user experience. Overall, Velt significantly simplifies the integration of collaborative features, making it a powerful tool for developers looking to enhance their applications.
