Kimi K3-256k

Kimi Code offers models K3 and K2.7 Code, switchable via model IDs in clients/tools; switching invalidates context cache, requiring new sessions for optimal results. Plan tiers restrict access to K3, 1M context, and HighSpeed features, with specific upgrade requirements and setup adjustments for K3's max reasoning effort and 1M context window.

Handbook.md shows that long policy documents do not reliably govern agents

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Researchers created a benchmark of 65 tasks to test language-model agents following long policy documents. The benchmark, which simulates real-world work environments, found most agents failed to consistently follow policies due to issues like overriding rules and losing details over time.

Commodification of Intelligence: Good, Bad, and Ugly Circular AI Deals

https://www.emergingtrajectories.com/assets/677d5ee3d185dd5dede0a75e/67a0d0ade0b78706efd6a5d8_heropink.png
The AI industry is evolving to commodify AI, making compute capacity a fungible commodity like electricity, with circular deals enabling companies to access necessary resources. These deals, common in traditional commodities markets, help companies like startups and hyperscalers access capital and resources, but can become risky if overextended or hidden from investors.

Document-borne AI worms can self-propagate through Copilot for Word

How much can you delegate to agents?

Countries with broad social protection and open capital accounts tend to pair well, while those with pension-heavy welfare and tight restrictions do the opposite. Welfare states can be seen as macroprudential policy, absorbing global finance shocks through broad social protection.

Self-hosting Kimi K3: 20% more hardware cost, 20% better task resolution

https://aistack.imec-int.com/assets/img/gpu.jpg
Organizations are facing high costs from AI API usage, with median employee spending $140 per year and 90th percentile near $7,300, due to token-based billing models. To mitigate costs, organizations can consider alternatives such as API routers, cheaper model tiers, or self-hosting their own GPUs, but the decision depends on factors like utilization, concurrency, and model quality.

A Trampoline

I didn’t want to buy a trampoline. It wasn’t the money. It was the fact that just about every trampoline I’d seen in somebody’s garden looked like a sad, weather-beaten thing. And I never saw children playing on them. I reasoned that the novelty factor was pretty strong for a trampoline - you love them for an hour the first time you get one…but are you really going to spend hour-after-hour, ...

GPT-5.6 vs. Claude Fable 5 for Physical AI, which performs best?

https://framerusercontent.com/images/zsGtVGVvu1F0gBl160qdoLs0oAM.webp?width=2400&height=1350
Researchers tested four frontier models (Fable, Sol, Luna, Terra) on five modeling and simulation problems. Fable achieved the highest difficulty-weighted score, while Sol was the most cost-effective. The Dyad AI harness significantly improved model performance, with the same model scoring 0.899 in the harness and 0.533 in a stock coding agent.
