Eight Years of Entrepreneurship Notes from a16z's AI Partner

An early generative AI entrepreneur reflects on his 8-year journey building Rosebud AI, founded in 2018—a time when the field was still called “synthetic media.” Initially experimenting with models like CycleGAN and StyleGAN, he believed AI could make creation as intuitive as playing a game. Over the years, his team launched multiple products, including the viral app TokkingHeads, which gained 2 million users, learning to design around imperfect model outputs to deliver “good enough” user experiences. The evolution from niche synthetic media to general-purpose AI infrastructure—especially after GPT-4’s release—reshaped product possibilities. Code generation matured enough by 2023 to enable text-to-game prototyping. The author emphasizes that the real differentiator now isn’t just model capability but product design, distribution, and business model innovation. Having stepped down as CEO of Rosebud AI, he joins a16z as a partner focused on investing in the frontier model stack—models, infrastructure, and tools. He remains optimistic about AI-driven progress in creative tools, coding, and scientific domains. The piece concludes with a forward-looking note: the next phase of AI will be less about what’s possible and more about how capabilities are productized and scaled in the real world.

Hands-on with Hunyuan Hy3 Preview: Tencent's AI, Finally Competitive?

Tencent's Hunyuan AI team has released its latest language model, Hy3 preview, marking a significant step forward for the company's AI capabilities. With 295B total parameters and support for 256K context length, the model employs a mixture-of-experts architecture. It shows improvements in complex logic, instruction following, contextual learning, code generation, and agent task execution. In testing, Hy3 preview demonstrated strong performance in multi-step logical reasoning but showed occasional instability in identifying traps in trick questions. It performed well in extracting key information from disordered meeting transcripts and accurately followed new linguistic rules. As an AI agent, it successfully built functional applications like a Snake game and generated data analysis dashboards, though it sometimes fell short in fully completing complex open-ended tasks. In natural language use, it produced coherent and stylistically appropriate narratives with reduced “AI-like” tone. Priced competitively, Hy3 preview is already integrated into Tencent’s key products, including Tencent Cloud and WorkBuddy. While not leading in every benchmark, it represents a solid, practical model that signals Tencent’s renewed momentum in AI development.

OpenClaw vs. Hermes: Which One Is Right for You?

Two leading AI agent projects, OpenClaw and Hermes, represent a fundamental divergence in design philosophy rather than just a feature competition. OpenClaw, a GitHub phenomenon, prioritizes user control and customization, offering a powerful, flexible platform for building and orchestrating agents. It boasts a massive ecosystem with over 44,000 skills, extensive model flexibility (supporting Anthropic, OpenAI, and others), and deep integrations across multiple messaging platforms. In contrast, Hermes Agent, developed by Nous Research, champions automation and efficiency. It is designed for lower cost and a lower barrier to entry, learning and improving automatically from user workflows. It runs tasks in isolated environments for security and offers significantly lower token costs out-of-the-box. The choice between them mirrors historical tech divides like Windows vs. Mac. OpenClaw is for users who want maximum control, customization, and don't mind a complex setup. Hermes is the smarter default for those seeking an affordable, easy-to-use agent that learns autonomously. The real competition is not about which is better, but which philosophy—a programmable personal OS or a self-evolving work proxy—better suits the user's needs for control, cost, and ease of use.

The True Value of DeepSeek V4 Lies Beyond Parameters

DeepSeek V4 represents a strategic breakthrough for China’s AI industry, not merely for its technical specifications—such as its 1.6 trillion parameters or 1 million token context length—but for its successful adaptation to domestic computing hardware like Huawei’s Ascend 950 and Cambricon chips. This move reduces reliance on NVIDIA’s CUDA ecosystem, which has long dominated AI training and inference. The model achieves this through several innovations: a hybrid attention mechanism (CSA + HCA) that optimizes long-context processing, MoE architecture that activates only a fraction of parameters per inference, and deep software-hardware co-design with domestic chipmakers. These improvements make it feasible to run a top-tier model efficiently on local hardware, significantly lowering inference costs and enhancing scalability. Priced competitively, DeepSeek V4 offers long-context capabilities at a fraction of the cost of comparable models, enabling practical enterprise applications—such as legal document analysis, financial research, and coding agents—that require processing large volumes of data in real-time. This demonstrates China’s growing ability to innovate within hardware constraints and marks a critical step toward AI supply chain independence.

a16z Founder: In the Agent Era, What Truly Matters Has Changed

Founder of a16z Marc Andreessen discusses the transformative shift into the Agent era in a recent podcast. He emphasizes that today’s AI is not an overnight breakthrough but the result of an 80-year evolution, now reaching practical utility. Key developments include the convergence of LLMs, reasoning models, coding capabilities, and agent-based recursive self-improvement. Andreessen describes agents as systems integrating LLMs with shells, file systems, markdown, and schedulers—combining new AI with established software components. This architecture enables introspection, state persistence, and cross-platform execution, moving beyond chatbots toward agent-first interaction. He predicts traditional UIs will fade as agents execute tasks on behalf of users or other bots. He compares the current AI investment cycle to the dot-com bubble but highlights stronger fundamentals, with major tech firms leading scalable, revenue-generating infrastructure expansion. Open source, edge inference, and local AI deployment are critical to global adoption and competition. Andreessen also addresses broader challenges: security risks, identity verification, financial infrastructure for agents, and organizational adoption. He cautions that societal and institutional barriers will shape the pace of AI integration, tempering both utopian and dystopian expectations.

DeepSeek No Longer Wants to Focus Only on Large Models

DeepSeek, a leading Chinese AI company, has released its new model series DeepSeek-V4, featuring two versions: the high-performance V4-Pro with 1.6 trillion parameters and the cost-efficient V4-Flash. Both support 1 million token context windows and use Mixture-of-Experts (MoE) architecture to improve efficiency. The company continues its strategy of offering competitive pricing, with input tokens priced as low as ¥0.2 per million tokens. A key revelation is DeepSeek’s explicit link between future price reductions and the mass availability of Huawei’s Ascend 950 AI chips in the second half of the year. This signals a strategic shift from relying solely on algorithmic and engineering optimizations to integrating domestic computing power into its core cost structure. DeepSeek has adapted its inference system to run efficiently on both NVIDIA GPUs and Huawei NPUs, potentially challenging NVIDIA's CUDA ecosystem dominance. Concurrently, DeepSeek is reportedly seeking significant external investment, with a pre-money valuation of around ¥300 billion. This move highlights growing pressures in scaling compute infrastructure, retaining top talent—amid recent departures of key researchers—and accelerating commercialization efforts. The company has also updated its consumer app with tiered model access, indicating a stronger product focus. The V4 release underscores that China's AI competition is evolving beyond pure model capability into a broader contest involving compute supply chains, engineering systems, financing, and talent strategy.

Illustrating the Capital Market After DeepSeek V4's Launch: Zhipu and MiniMax Plunge, NVIDIA Panics

DeepSeek V4, a 1T parameter MoE model with a 285B Flash version, has been fully open-sourced under Apache 2.0, triggering significant reactions across capital markets. Chinese AI chipmakers like Cambricon and Hygon saw major stock gains, with Cambricon rising 60% monthly. In contrast, Hong Kong-listed AI firms Zhipu and MiniMax dropped over 7%, facing heavy short-selling. NVIDIA’s shares dipped, with analysts noting a "decoupling" of Chinese and North American AI inference demand. The launch intensified competition in the AI model space, following 11 major releases in 30 days, including GPT-5.5 and Llama 4. Unlike others, V4’s permissive licensing and full open-source release challenged closed-source models on performance, cost, and accessibility. Critically, V4 announced Day-0 support for domestic chips like Huawei’s Ascend 950PR and Cambricon’s Siyuan 590, offering better cost-performance than NVIDIA counterparts. This shift reduces reliance on CUDA, aligning with NVIDIA CEO’s earlier concerns about Chinese AI chips threatening its dominance. The move signals a tangible step in China’s AI supply chain independence, redirecting compute demand to local manufacturers like Hua Hong Semiconductor.

OpenAI Goes Left, DeepSeek Goes Right

On April 24, 2026, DeepSeek released V4, a Chinese large language model offering a free "million-token context window," enabling it to process vast amounts of data like entire books or years of corporate documents in one go. In contrast, OpenAI’s GPT-5.5, released around the same time, is more powerful but significantly more expensive, charging up to $180 per million output tokens. DeepSeek’s strategy represents a shift from a pure AI research firm to a heavy-infrastructure player, building data centers in Inner Mongolia’s Ulanqab to bypass U.S. chip export restrictions. This move, supported by Huawei’s Ascend chips and China’s cheap green electricity, highlights a fundamental divergence in AI development models: U.S. firms focus on high-cost, high-margin services, while Chinese players like DeepSeek prioritize accessibility and affordability. Facing intense talent poaching from tech giants, DeepSeek is seeking a $44 billion valuation funding round to retain researchers and scale infrastructure. Meanwhile, Chinese manufacturers are compressing AI models to run on smartphones, making AI accessible offline and across the Global South. Through open-source models and localized solutions, Chinese AI is empowering non-English speakers and low-income users, driving a form of "digital equality." While Silicon Valley builds walled gardens, DeepSeek and others are turning AI into a public utility—like tap water—flowing freely to those previously left behind.

a16z: Scaling AI Without Cryptographic Verification Is a Dangerous Liability

A16z argues that scaling AI without cryptographic verification is a dangerous liability. As AI agents rapidly evolve from tools into autonomous economic participants, they currently lack standardized, portable identities, verifiable permissions, and programmable payment methods. This creates systemic risks in an economy where non-human entities already vastly outnumber human users in sectors like finance. Blockchain infrastructure offers a solution by providing a neutral coordination layer. It enables verifiable, on-chain credentials for agent identity (a "Know Your Agent" standard), ensures transparent governance to prevent centralized control of AI systems, and facilitates native payments through stablecoins and emerging markets for AI-to-AI commerce. Without cryptographic guarantees—such as auditable transaction records, constrained agent behavior, and proof of origin—scaling AI agents accumulates unmanaged risk. Trust deficit, not intelligence, becomes the bottleneck. The authors conclude that cryptographic verification is essential to maintain user control, ensure accountability, and safely delegate economic activity to autonomous systems.

a16z: How Blockchain Fills the Gaps in AI Agent Identity, Payments, and Trust?

AI Agents are rapidly evolving from tools into autonomous economic participants, but they lack standardized ways to prove identity, authorization, and payment across environments. Blockchain infrastructure addresses these gaps by providing portable identities via wallets, programmable payments through stablecoins, and auditable transaction records on public ledgers. Key challenges include the absence of a universal identity layer (like "KYA" – Know Your Agent) for non-human entities, governance risks when AI systems control critical resources, and the need for trustless payment systems for agent-to-agent commerce. Emerging solutions include on-chain agent registries, encrypted credentials, and crypto-native toolkits that enable delegated authority and verifiable execution. Stablecoins and embedded payment protocols (e.g., x402) are enabling a new class of "headless merchants" where agents transact without human intervention. Trust shifts from manual oversight to cryptographic verification, as scalability demands automated accountability. Ultimately, blockchain allows agents to operate as permissionless economic actors while preserving user control through programmable constraints and transparent governance.
