Some wild numbers from Adapty’s Q3 benchmarks: • Median cost per trial: $25 • Top 25% still paying $16.50/trial • Median cost per payer: $65 ($27-$95 P25-P75) It’s competitive out there. You almost have to be performing in the top quartile or better to make the unit economics work. Worth a read if Meta Ads is a meaningful acquisition channel for your app. Very helpful @xburak @adapty
HERE WE GO!! THE STATE OF META ADS IS OUT! Is your Meta Ads performance actually good? Or are you just getting started and wondering how much you should spend, which countries to target, and what results to expect? We've got the answers! We’ve built one of the most comprehensive Meta Ads benchmark reports out there, packed with insights that would normally cost you $1,000+. And we're giving it away FOR FREE! ENJOY!!! go.adapty.io/adapty-meta-gui…

Wow this is really cool
Introducing Reality-Aware Rendering in @Simulon, a completely new way to create with the real world. Place neural assets with your phone and act out the scene. When you stop recording, Simulon renders the take, reading everything in it (what you do, what you say and the place around you), and your assets respond to all of it. The final is regenerated from your recording: a new performance of the scene, not a copy of the footage. Available now on iPhone. Coming to Android soon.

The hardest lesson NFL MVP Steve Young ever had to learn. "Fear-based thinking is a liar. I was afraid of failure, so much so that I paid this price so that I could have success. I learned as an older person, that's a fallacy. That's fraudulent." "I'm not going to pay for success with my worry and fretting. Man, fame is a thief. Fear-based thinking is a thief. There's a lot of thieves in life."

me: how do i open pdf claude: You're right to ask. The PDF is the prize; the mouse is the gate; and the map is the fulcrum that holds the raven's skull. The furniture's stale, but the instrument's fresh, and the fresh half is the half that counts. I deleted your home directory.

Just read through & this is a HUGE deal for AI in financial industry - here is why: 1. Private on-chain authentication enables AI agents to perform transactions w/out revealing user identities or decision logic. 2. time-based or amount-based complex authentication policies allows AI systems to execute more sophisticated, programmable tasks while maintaining user confidentiality, potentially reducing risks of targeted attacks on AI-managed accounts. 3. Compatibility with account abstraction streamlines AI-driven wallet management by replacing private keys with smart contract logic. 4. ability to hide authentication policies from validators aligns with growing regulatory scrutiny on data privacy (EU's GDPR updates in 2024 e.g.) making AI systems using zkAt more compliant/appealing for global economic applications - Web2 financial institutionally ready. 5. Groth16 leverages a proven ZK proof system, potentially lowering computational costs for AI systems compared to other privacy solutions like MPC threshold wallets, thus improving scalability in AI-driven financial ecosystems. Real assets can truly be programmable and automated. 6. AI could facilitate fully private financial pipelines, possibly disrupting traditional fintech models by enabling trustless, anonymous AI-managed investments starting as early as late 2025. 7. This enables AI to manage organizational policies privately, potentially transforming how AI governs economic entities in decentralized systems, therefore redefine trust. People talk abt how Web3 is critical for AI economy but usually vague even conceptually, but these guys have just done it. Mark it as a major milestone 👇👇👇🧠🧠🧠🚀🚀🚀
🚀 Sui's new innovation, zkAt (spelled zee-cat), can be Bigger than all zkLogin, Plasma and Lightning Network together. Why? eprint.iacr.org/2025/921.pdf Introducing zkAt (Zero-Knowledge Authenticator), a first-of-its-kind blockchain primitive that: 🧠 Hides the authentication policy itself, even from validators. 🧶 Supports arbitrarily complex rules: time-based, amount-based, multi-algo thresholds, zk inside zk, game-solving vs public keys, what?? ♻️ Enables oblivious updates with zkAt+ (change zk policies without changing user's address, what???) ✅ Compatible with account abstraction, in Sui we'll aim for a native authenticator, ideal for custodians and users obsessed with their privacy 🥷 High-probability this will be the major competitor to MPC threshold wallets, this time with pure ZK 🧢 It’s like account abstraction + threshold signatures + zk in one, but truly private. 🚀 Enables private programmable pipelines, aka zk tunnels, opening the door to encrypted DeFi, anonymous voting, stealth wallets, DAO treasuries, and more. Note1 (for cryptographers): Groth16 is not dead, we found a new property, and use case that makes it a better scheme than its competitors. Note2 (for DeFi): Starting from today, personally representing the science-nerds of Sui, Walrus and Mysten Labs, I'm switching mood. Kept this hidden for 3 days with zero sleeping time, constant doctor's help to monitor my help, but the other important topic smoothly finds its way. Huge efforts on the background, day and night, to protect users and traders with the tremendous help of @EmanAbio and @web3crusadr. Good morning

I'm trying out Prompt to Design tools this week. Galileo AI was bought by Google and announced yesterday as @stitchbygoogle Has anyone tried any others? Stitch gives both code and figma formats, and very promising so far from the tools I'm trying. Would love to hear your experience and exchange notes.

We're witnessing the fastest consolidation in the history of developer tooling. Seriously, it's never moved this fast before. Blink, and you might miss another billion-dollar acquisition or the release of yet another AI coding agent. And here we are, trying to catch breath and make sense of it all. If you're a developer, or even vaguely tech-adjacent, you absolutely need to pay attention, because the implications are massive. A brief "history" lesson first. Back in February 2025 AD, Anthropic Claude Code research preview, the first notable CLI coding assistant. The tool was smooth, and the model powerful. Recently, on the @latentspacepod podcast (@swyx), they stated that Claude Code wrote around 80–90% of its own code. Talk about bootstrapping on steroids. Today, they have released SDK for devs to build composable coding agent tooling. Not far behind was OpenAI, which released Codex CLI, a conversational, terminal-based coding assistant that felt magical when it first debuted. (I even forked Codex CLI myself to understand its token usage and workflow, check out my gist if you're curious.) Meanwhile, in the open-source corner, we had Aider. Then Sourcegraph's Amp joined the fray in May, removing its waitlist and allowing anyone to spin up multistep agents with a simple agent(.)md file. Cursor's trajectory is most fascinating. Originally just another fork of VS Code, Cursor quickly became a developer favorite and is now a SaaS unicorn with a rumored $10 billion valuation. Cursor also shook things up recently by introducing unlimited completions and shifting their MAX model to API-based pricing, subtle moves, sure, but these reflect the reality that foundational model providers are adjusting their pricing strategies as market realities hit, and everyone is still adjusting and competitors are building pressure. In the middle of this craziness, OpenAI decided it wasn't playing games and threw $3 billion at Windsurf, making clear their intent to dominate developer tooling. Google's latest entry, Jules, they are still keeping me on the waitlist, competing with Codex and Copilot by integrating with GitHub and leveraging ephemeral cloud environments for asynchronous development. So, what’s the story beneath all this chaos? Here’s where my analyst hat goes on. I see five mega-trends shaping up: 1. The Commoditization of Interfaces No one cares about IDE loyalty anymore. Seriously, who has time to be loyal when every agent, whether it’s Cursor, Windsurf, or Jules, essentially offers the same basic functionality? Developers hop between tools—I've jumped from Cursor to Windsurf to Claude Code, chasing convenience or a few extra free API calls. UI and UX alone won't save companies; they'll need something deeper to hold developers’ attention. 2. Token Economics & The Coming Crunch We’re still in the "token-first" world, where every provider optimizes for token consumption because that's their revenue model. Yet, having explored the API calls, I noticed just how aggressively inefficient these tools can be. This inefficiency won’t last. Once subsidies fade and true market prices hit, companies offering smarter, token-efficient solutions will win. The future belongs to the most cost-conscious innovators. 3. Agent Simplicity and Spec-driven Workflows Here's something wild: almost every agent today is powered by simple plaintext rule files. Think .cursor/rules, CLAUDE(.)md, agent(.)md. Today's "state-of-the-art" agents are basically glorified text lookups against structured specifications. The complexity we see is actually smoke and mirrors. The real challenge—and opportunity—is evolving these basic setups into something more robust and persistent. 4. Memory is the New Frontier Current AI agents are embarrassingly forgetful. Seriously, every new task rebuilds context from scratch. It's like they have goldfish memory—zero persistence. The next massive leap forward in AI tooling will revolve around intelligent, persistent memory systems. Can your agent remember past interactions, avoid redundant work, and ground new tasks in existing knowledge? Whoever solves this elegantly will dominate the next wave. :wink-wink: 5. The Flywheel Effect & Incumbent Domination OpenAI, Anthropic, and Google—the foundational giants—are spinning up data centers at unprecedented scales, optimizing for margins. This creates a flywheel effect: each improvement fuels more user adoption, more feedback, and even greater market dominance. Jeff Bezos famously said, "Your margin is my opportunity." The biggest players are living this motto right now, making it exceedingly hard for smaller entrants to compete directly. So, where will we be next year? I predict an intensified battle around memory persistence, token efficiency, and more than spec-driven automation. In order to reach general adoption, tools that intelligently reuse context, minimize API overhead, and streamline spec-to-code workflows that bring in observability will explode in popularity. Meanwhile, smaller or niche tools will struggle unless they offer significant breakthroughs in memory management or ultra-specific domain expertise. > Bottom line: We're at an inflection point. Developers have never had it so good, yet the stakes have never been higher. Those who adapt quickly—embracing efficiency, innovation in memory systems, and smarter token consumption—will shape the next steps. Blink again, and the entire landscape could shift. DISCLAIMER: Some AI slop included, but in general this is it, plus leaving some for the next iteration.

Been using Gemini 2.5 for analysis work this week and it's been great. How is Gemini 2.5 for coding? Anyone tried it? Just have been seeing more people talk about it, e.g. "This feels like the first model since 3.5 Sonnet was released that is a real step change. In performance, agentic qualities, and context window it's insanely impressive. This is IMO the best model to use in Cline."
