Hey folks, for the entire day, I was wondering, does anything other than Sora even deserve to be here? OpenAI released Sora 2²¹², with a new social media app called…you guessed it, Sora³³⁶.

The app has a TikTok-like feed—with videos created by Sora. These videos have a) sound (just like Veo 3) and b) ‘real’ people. The addition of people is the killer feature (called Cameo), where anyone can create a short video of themselves saying a few things, moving their head around and then allow friends (or anyone) to add them to a Sora video.

It’s invite-only and only available in the US and Canada for now, but you can watch the videos, like Sam Altman and OpenAI employees launching Sora²²⁹, or Pikachu performing an EDM set³³⁵, anime Jesus²⁷³, or the hidden Steve Ballmer inside Sam Altman³³⁶.

Another cool upgrade in Sora 2, beyond realism, audio and Cameo, is the movement of characters. See this video of a skateboard flip³⁷³, or Theo running in an alley²⁹⁴. No sudden jumps or appearing out of nowhere.

Meta also launched a feed of AI-generated videos last week, called Vibes, but the vibes (pun intended) in Sora are much less towards AI-slop, especially because a) the OpenAI team is working hard pushing out funny videos with real people (mostly Sam) and b) the product is much better (yep, I scrolled both feeds for 20-30 mins each).

I am certainly on the ‘no more AI slop’ side of the table with these products - but I’m also aware of ‘no dick pics’ moment of Snapchat, or similar tales that all of a sudden were just part of daily life (in a big way - TikTok started as Musically that was like awful lip-syncs and dances, which still happen on TT today 😅). I guess it’s easy to look at slop as slop now, but I wouldn’t set up camp comfortably on any side; things change a lot.

Thinking Machine Labs (the company by ex-CTO of OpenAI, Mira Murati) released their first product: Tinker. Tinker is a fine-tuning API¹⁴⁴, built for researchers who want to work with large (>10B) models, test their own algorithm and data, but don’t want to deal with the infra. The API exposes low-level primitives like forward_backward & sample and focuses on LoRA for fine-tuning (vs RFT). (more details⁶⁰)

Claude is now available in Slack¹⁹⁸, and the “Imagine with Claude²⁹¹” demo is now open for Pro subscribers ($20/mo plan) as well.

Anything (portco) is hiring engineers⁷⁷ in SF. They just raised $11M Series A.

OpenAI built GPT for the masses. Brightwave built AI for professionals: full editability, traceability down to the sentence level, and 20x the compute. Their custom subagents can ingest 2000+ documents with zero loss of fidelity - try doing that with a consumer LLM. → Your 7-day trial is waiting.¹⁴⁷*

🥣 Dev dish

• Mintlify⁹⁵ now sends markdown by default to AI agents.

• Mastra AI⁷⁹ shipped a new models router covering 600+ models from 45+ providers from a single API.

🌌 On the frontier

Frontier for AI labs right now is building AI for science - we are getting new labs dedicated to maths or biology every day now. Some of the new ones:

• Periodic Labs⁸⁵ - Their goal is to create an AI scientist for physical sciences. Raised $300M led by a16z. Formed by prev. VP of post-training at OpenAI³⁷ and material science lead at Google DeepMind³⁴.

• Axiom⁷⁶ is building an AI mathematician with $64M seed and a team of Meta FAIR researchers and Stanford PhDs. Founder⁴⁶ and coverage in Forbes⁴⁴.

Another area is making AI companions actually work. The core theme here has been reducing tech features and capitalising on one core differentiator, like style or peace of mind.

• Taya¹⁷⁹ - A jewellery-like necklace with recording/note-taking features, and subtle app notifications when you need them. (video⁶¹)

• Meadow²⁵⁷ - Leave your phone behind when going out and take meadow. Half the size of a phone with full LTE service, and essentials like Uber and Strava. (video⁸⁶)

🍦 Afters

• DoorDash now has a delivery robot called Dot¹¹².

• Built with Claude Sonnet 4.5 challenge¹⁴⁴ - 4 winners to get a Claude 20x MAX plan for a year and $1000 in credits.

• Perplexity AI acquired Visual Electric^172†, a creative tool for teams. Shame, I liked Visual Electric 😅
