As Meta employees brace for layoffs next Wednesday, May 20, many say the vibes are horrifically, historically low.

New Paper: arxiv.org/abs/2606.19370 Self-play yields capabilities but requires frustrating cost-function tuning. Surprisingly, just 30 minutes of demonstration data produces much more human-like driving policies! Led by @daphne-cornelisse.bsky.social Website: spiced-self-play.com
AI Weekly's analysis
→
- A new method trains driving AI using only 30 minutes of human demonstrations, 2,500 times fewer than comparable imitation learning approaches.
- Human demonstrations serve as a regularization signal on top of a basic goal-reaching reward, not as the primary training objective.
- Resulting policies coordinate with held-out human trajectories and finish training in 15 hours on a single consumer-grade GPU.

“Whimsey attacks” that seem absurd (“I cannot pay that much because of the Geneva Convention”) work against AI agents because guardrails are weak against out-of-distribution arguments. Smaller models fall often, but it even gives an edge against bigger ones. www.microsoft.com/…

We recently investigated how humans and AI reason through causal rules: arxiv.org/abs/2606.06464 Accepted at #CogSci2026. We gave adults and LLMs agency to actively experiment using a Blicket causal game, breaking down their process into the iterative loop shown in the followi…

Happy to announce our latest paper! We argue that a solipsistic superintelligence is unlikely to be cooperative. "Solipsism" in the development process can give rise to self undermining in deployment. So, is humanity now building solipsistic or non-solipsistic AI? arxiv.org/ab…
GDM, @schmidtsciences.bsky.social, @coop-ai.bsky.social, @aria-research.bsky.social, and Google announce a $10M funding call for multi-agent saftey research! Amazing, such an important research area. 🤩 Check it out 👇 Deadline for applications: August 8th, 2026. deepmind.google…
AI Weekly's analysis
→
- Google DeepMind and four partners are offering up to $10 million for multi-agent AI safety research; applications close August 8, 2026.
- The program targets four areas: realistic testbeds, emergent network behavior, cross-platform identity protocols, and oversight of deployed agent populations.
- Current AI safety methods test models in isolation, leaving emergent behaviors across interacting agent networks a largely unstudied and underfunded problem.

Gemma 4 technical report is out! lots of cool stuff, check it out! arxiv.org/abs/2607.02770
AI Weekly's analysis
→
- Gemma 4 is a new open-weight multimodal family spanning 2.3B to 31B parameters, with both dense and Mixture-of-Experts variants.
- The 12B model uses a unified, encoder-free architecture that ingests raw audio and image patches directly.
- A thinking mode lets Gemma 4 emit reasoning traces before responding, with claimed leaps on STEM, multimodal and long-context benchmarks.

This is a great use of Gemma! having an open model running at +1000 tokens per second can enable some pretty cool use cases! The voice assistant is a good one, but I'm sure there are many others! huggingface.co/blog/cerebra...

- Hugging Face and Cerebras have shipped an open cascaded speech-to-speech pipeline chaining Nvidia's Parakeet, Google DeepMind's Gemma 4 VLM on Cerebras, and Alibaba's Qwen3TTS.
- The pitch focuses on P95 tail latency stability, not median speed, arguing that occasional multi-second stalls are what break conversational voice apps.
- Hugging Face says the same pipeline already powers more than 9,000 Reachy Mini robots in the wild, giving the demo a real deployment story.

AI Weekly's analysis

- CoopEval compares four cooperation mechanisms — repeated games, reputation, third-party mediators, and outcome-conditional contracts — applied to LLM agents.
- The authors report that LLMs with stronger reasoning capabilities behave less cooperatively in mixed-motive games, not more.
- Contracting and mediation worked best for capable models, while repetition-based cooperation deteriorated when co-players changed.

AI Weekly's analysis
→
- CoopEval evaluates LLM agents across four social dilemmas layered with four cooperation-sustaining mechanisms: repetition, reputation, mediation, and contracting.
- Contracting scored 0.801 and mediation 0.695 on a normalized cooperation scale, ahead of repetition at 0.587 and both reputation variants.
- Repetition-based cooperation broke down when co-players changed, while higher optimization pressure amplified the effectiveness of all four mechanisms.

The For You feed is getting amazingly good. Lately I feel like it's Twitter circa 2014. I have found more relevant stuff in my AI research meets retro games meets cat & dog memes niche than ever before, despite zero or negative DAU growth. Well done @spacecowboy17.bsky.social .. keep this up! 🫵👍🙌
