Creative & Visual Media

Heather Cooper (@HBCoop_) showcased multiple AI-generated visuals and videos, including a Midjourney set using –sref for stylized images,

a quick Replit Animation video created from a single-line prompt in under 5 minutes,

and other artistic pieces exploring themes like time and emotion. Ilker (@ailker) shared an AI-generated video tribute to Victor Osimhen’s journey.

Cristóbal Valenzuela (@c_valenzuelab) promoted Runway’s aggregation of leading generative video models including Kling 3.0, Sora 2 Pro, and others for content creation in film, ads, and social posts.

AIWarper highlighted Sonauto.ai, an uncensored music generator capable of imitating any existing artist’s style, describing it as “ridiculously uncensored” and urging others to use it before potential changes.

Examples included AI-generated tracks mimicking Lamb of God and a pro-AI song in the style of Rage Against the Machine.

Justine Moore (@venturetwins) highlighted breakthroughs in AI-generated UGC videos using Seedance 2, noting that videos can be created from a single product photo with minimal prompting like “ugc video of a young woman in her bathroom talking about how she uses the reset undereye patches putting them on.” These outputs look and feel real, enabling one-shot unboxing and other content without scripts or start frames.

She also shared a funny AI video example and discussed its rapid generation capabilities.

Machina (@EXM7777) described Opus 4.6 with custom skills, MCPs, and swipe files as “practical AGI for marketing,” producing outputs superior to 95% of manual marketers, emphasizing personalized knowledge bases for content edges.

Ethan Mollick (@emollick) showcased Claude Code generating a full horror game based on William Carlos Williams’ poems “The Red Wheelbarrow” and “This Is Just To Say,” including writing, design, and unnerving hand-drawn graphics.

Software Development

Simon Willison noted that regular Claude chat can now clone public GitHub repos, enabling analysis or use as artifact starting points.

@levelsio recommended prompting Claude Code subagents to review and improve code.

Omar Sar discussed Recursive LLMs (RLMs), praising GPT-5.2-Codex as particularly effective for code tasks, long-context handling, and large-scale analysis, outperforming models like Gemini 3.1 Pro and Claude Opus 4.6.

Ethan Mollick (@emollick) demonstrated Claude Code’s capabilities by prompting it to build a horror game from poetry, handling all creative coding and design elements effectively.

Machina (@EXM7777) compared Claude Code (specialized for coding/marketing) to broader agents, noting its excellence but limitations for non-specialized tasks.

Automation & Orchestration

Goose_OSS announced Goosetown, a multi-agent orchestration layer for their Goose agent, enabling subagents across worktrees inspired by Gas Town, moving beyond single-threaded execution.

Omar Sar shared research on emergent behaviors in large-scale LLM agent populations, noting newer models lead to worse societal outcomes in social dilemmas and highlighting risks of poor equilibria.

Simon Willison commented on Cursor’s agent sandboxing using deprecated macOS tools, also used by OpenAI Codex.

Machina (@EXM7777) praised OpenClaw as an always-on generalist agent with life memory, voice integration, heartbeat/cron jobs for autonomy, and a “soul” like a co-founder, contrasting it with specialist tools. Tips included deep interviews, manual memory training, GPT-5.3-Codex model, and skill builders for workflows.

POM (@peteromallet) succinctly stated “Everything is agent,” reflecting the shift toward agentic systems.

Strategy & Ecosystem

Cristóbal Valenzuela (@c_valenzuelab) outlined the AI-driven shift to “bespoke everything,” enabling one-to-one production where the cost of creating custom software, movies, or workflows approaches the cost of inference, moving beyond one-size-fits-all models.

Guillermo Rauch (@rauchg) emphasized adapting to the post-AI era by minimizing meetings, maximizing deep work, and building self-driving infrastructure and agents to amplify individual impact, positioning Vercel as the “world’s largest startup.”

Alex Volkov (@altryne) recommended deploying fleets of OpenClaw devices for personal use, hinting at accessible AI hardware trends.

Simon Willison celebrated ggml.ai (llama.cpp creators) joining Hugging Face, crediting it with sparking the local model revolution in March 2023 via efficient personal hardware inference.

Dan Shipper joked about OpenAI’s GPT-5.3-Codex-Spark achieving 1200+ tokens/second.

@levelsio argued AI-generated ephemeral UIs could outperform complex sites like Airbnb, critiquing traditional design efforts.

Emad Mostaque praised Taalas’ chatbot for “instant intelligence.”

Ethan Mollick (@emollick) discussed AI benchmarks, noting METR long-task scores correlate highly with major AI ability measures, validating its use as a progress indicator.

He predicted waves of market disruption as AI use cases clarify across industries.

On norms, he highlighted widespread undisclosed AI transcription in calls, urging rules for searchable outputs.

He amplified Sam Altman’s view of faster-than-expected takeoff to extremely capable models, stressing preparation.

Gemini 3.1 drew a TikZ unicorn, echoing early “Sparks of AGI” capabilities.

Justine Moore (@venturetwins) posted “State of the Internet in 2026,” capturing ecosystem shifts (image depicts evolving trends).
