Unlike social networks where user-generated content creates strong lock-in, AI chatbots have a fragile hold on users. A user switching from ChatGPT to Gemini experienced no loss from features like personalization or memory. Since the "content" is AI-generated, a competitor with a superior model can immediately offer a better product, suggesting a duopoly is more likely than a monopoly.

Even with comparable model quality, user experience details create significant product stickiness for LLMs. Google's Gemini feels much slower than ChatGPT, and ChatGPT's mobile app includes satisfying haptic feedback. This superior, faster-feeling UX is a key differentiator that causes users to churn back from competitors.
Traditional SaaS switching costs were based on painful data migrations, which LLMs may now automate. The new moat for AI companies is creating deep, customized integrations into a customer's unique operational workflows. This is achieved through long, hands-on pilot periods that make the AI solution indispensable and hard to replace.
AI capabilities offer strong differentiation against human alternatives. However, this is not a sustainable moat against competitors who can use the same AI models. Lasting defensibility still comes from traditional moats like workflow integration and network effects.
While ChatGPT is still the leader with 600-700 million monthly active users, Google's Gemini has quickly scaled to 400 million. This rapid adoption signals that the AI landscape is not a monopoly and that user preference is diversifying quickly between major platforms.
Unlike sticky cloud infrastructure (AWS, GCP), LLMs are easily interchangeable via APIs, leading to customer "promiscuity." This commoditizes the model layer and forces providers like OpenAI to build defensible moats at the application layer (e.g., ChatGPT) where they can own the end user.
Despite its massive user base, OpenAI's position is precarious. It lacks true network effects, strong feature lock-in, and control over its cost base since it relies on Microsoft's infrastructure. Its long-term defensibility depends on rapidly building product ecosystems and its own infrastructure advantages.
Despite ChatGPT building features like Memory and Custom Instructions to create lock-in, users are switching to competitors like Gemini and not missing them. This suggests the consumer AI market is more fragile and less of a winner-take-all monopoly than previously believed, as switching costs are currently very low.
Unlike traditional SaaS where high switching costs prevent price wars, the AI market faces a unique threat. The portability of prompts and reliance on interchangeable models could enable rapid commoditization. A price war could be "terrifying" and "brutal" for the entire ecosystem, posing a significant downside risk.
Gemini is converting daily ChatGPT users not just with model capabilities, but with superior UX like better response sizing and perceived speed. Crucially, the trust in the Google brand for search is transferring to its AI, making users more confident in its reliability, even with less complex reasoning.
While personal history in an AI like ChatGPT seems to create lock-in, it is a weaker moat than for media platforms like Google Photos. Text-based context and preferences are relatively easy to export and transfer to a competitor via another LLM, reducing switching friction.
