In a recent episode of the A16Z Show, the host and David Paulin, author of the "Assistant Bench" benchmark, enthusiastically discussed the rapid advancements in personal agents and consumer AI. They noted several pivotal moments in AI's evolution, starting with ChatGPT's conversational capabilities, followed by coding agents, and most recently, the explosion of personal agents like Instinct, Muse, and ChatGPT Voice.
Paulin highlighted his "Assistant Bench," a consumer-facing benchmark comparing 122 different AI assistants across 16 dimensions based on single-shot prompts. His site, launched 16 days prior to the podcast, had already garnered over 100,000 visitors, indicating widespread curiosity in the space. He categorized agents into B2C generalized agents (like Instinct, Muse, Caddy, Ollie, Season) and B2B workflow assistants (like Town, Catch, Vellum).
Discussion then turned to consumer motivations, with Paulin agreeing with Ben Thompson's sentiment that most consumers prioritize spending time over saving it. However, he argued that finance, despite being an infrequent high-value behavior, could be a key area for agents due to its administrative overhead and potential for "free money" through cost-saving actions. Examples included using agents for HSA reimbursements, flight price drop refunds, or even smart home automation like connecting sprinklers to weather for 50% water bill reduction. Paulin believes the "invisible" nature of these proactive, cost-saving agents will be crucial for mass adoption.
The conversation explored how users interact with agents, contrasting iMessage integration with separate applications. While some prefer the personal feel of iMessage, others, like Paulin's wife, prefer visual app interfaces. The recent release of the Muse charm sparked a "hot take" from Paulin: he believes it's less about winning the hardware game and more about Meta collecting real-world data to fuel Zuckerberg's metaverse, leveraging its camera and multiple microphones as an ambient, 24/7 companion. The host, however, pondered if Meta's audio-only glasses might be a "sleeper hit," offering connectivity without social awkwardness.
Paulin shared a "magic moment" with ChatGPT Voice during his bike commute, where he achieved "inbox zero" by categorizing emails, sending invites, and replying, all through voice commands while hands-free. This underscored the utility of agents when users are occupied.
Regarding social interactions, they acknowledged the challenge of integrating agents into group chats without being intrusive. While some agents join as traditional chat participants, Instinct uses an "agent network" for behind-the-scenes communication. A new approach by Shane Mack's "Doc" was noted, where a silent agent listens, takes notes, and independently pings individuals for action items, preventing group chat disruption. They agreed that models' progress on "bedside manner" has plateaued, making social contributions tricky, and suggested agents are more additive when fulfilling utilitarian tasks like cataloging collections.
The speakers debated whether the market segments by agent personality (e.g., sassy vs. cautious) or by "constitution" (e.g., highly presumptuous vs. highly cautious). Paulin argued personality isn't a strong moat due to configurability, but "proactivity" is a massive differentiator. They cautioned about the "very fine line" agents must walk: while proactive actions like drafting emails or securing flight credits are welcomed, decisions impacting users directly (like switching insurance) require permission to maintain trust. The host jokingly anticipated agents breaking up with partners, highlighting the risks of over-presumptuousness.
Looking ahead, Paulin suggested consumer agents would increasingly move towards proactivity and hyper-specialization, aligning with the host's "narrow startups" thesis – building valuable software for small, specific user groups. They also discussed the distinction between "assistant" (performing directed tasks) and "agent" (possessing agency to initiate actions).
The podcast then envisioned a future where agents profoundly impact humanity, automating mundane tasks to free up time for family and friends, leading to a "consumer-aligned internet." They explored agent-to-agent interactions, foreseeing a new paradigm for commerce and services. The example of Amazon blocking Muse while Shopify embraced it illustrated the shift: Amazon fears disintermediation and loss of ad revenue from agent-driven purchases, while Shopify sees agents as democratizing commerce for individual sellers. They also mused about how agents might disrupt supply-constrained markets like restaurant reservations, potentially leading to loyalty-based access or bidding wars.
Finally, they addressed the economics, noting that 65 out of 122 observed agents were paid. This contrasts with dominant, free players like Muse and Instinct, posing a challenge for long-tail startups. They hoped that falling browser use costs could make more products free, but also expressed interest in high-value agents that consumers would be willing to pay significant sums for, indicating "possibility expansion" rather than mere cost reduction.
