Firebase Global Outage, OpenAI Platform Shift
This issue of The Pulse covers the global outage of Firebase's iOS SDK, which crashed apps using Firebase Analytics for 2-6 hours. Google failed to update its status page or provide a postmortem, criticized given its reputation for incident management. Also, OpenAI is evolving into a platform where users can allocate ChatGPT spend across open models and AI offerings from 16 partners, not just OpenAI's own models. Data from Vercel's AI gateway shows 60% of model spend goes to open-weight models, with OpenRouter confirming a shift towards open models. Additionally, a new take suggests CTOs and VPEs are leaving due to AI tools enabling solo or small-team development, rather than 'founder mode'.
Covers multiple topics: Firebase outage and AI model trends, but is a newsletter with no single major event. Moderate relevance to AdTech due to AI infrastructure implications.

AI Subscription API Value Compared: Claude Max, ChatGPT Pro, SuperGrok
This article compares the value of AI subscriptions versus API usage, focusing on Claude Max, ChatGPT Pro, and SuperGrok. The author tested frontier models (Opus 5.5, Sonnet 5.5, GPT-6.1 Sol) on real bug-fixing tasks. Key findings: GPT-6.1 Sol is over 10x cheaper than GPT-5.6 Sol on complex tasks; Opus 5.5 nearly matches Fable 5.1 at two-thirds cost; Sonnet 5.5 is efficient but slow. Subscriptions provide significant API value multipliers: SuperGrok offered 190x API value, Muse Code High Usage 114x, Claude Max 20x 45.3x, and ChatGPT Pro 10.25x. The author advises that for cost-efficiency, Grok appears best for western subscriptions, followed by Muse Code with data sharing. OpenAI's GPT-6.1 Sol is cheaper than Anthropic's Opus 5.5 despite lower multipliers. The article includes test data and links to benchmark results.
Benchmark Leads Funding in Chip Startup Tendrils Compute
Benchmark has won a competitive process to lead a new funding round for Tendrils Compute, an early-stage chip startup based in Cambridge, UK, according to sources. The company is already discussing a fast follow-up raise that could value it at over $1 billion. Tendrils is developing general-purpose chips based on interaction nets, an obscure graph-based computing model, aiming to address CPU bottlenecks in AI agent workloads. The deal reflects a broader resurgence in chip investments, with other startups like Etched, Fractile, OLIX, Euclyd, Delos Data, and Volantis Semiconductors raising significant capital. Venture firms are increasingly backing specialized chip startups due to the AI compute demand, despite the sector's capital intensity and cyclicality.
Broadcom Provides Anthropic $42B for Chip Leasing
Broadcom will provide Anthropic up to $42 billion to lease its AI processors, as revealed in Anthropic's IPO prospectus. This makes Anthropic Broadcom's largest customer, contributing about a third of its AI revenue by 2027. Broadcom follows Nvidia's model of financing customers to boost sales. Anthropic has also booked computing capacity worth $125 billion over coming years. The deal involves convertible bonds, with potential conflicts of interest noted. Anthropic aims for a market valuation over $2 trillion at its Wall Street debut. In 2025, Anthropic's revenue grew twelvefold to $4.6 billion, but operating loss nearly doubled to $8 billion due to rising computing costs. The company plans to invest $518 billion in AI infrastructure, with 80% contractually committed.
