[AINews] "Laguna S 2.1 Released: Cheaper than Deepseek v4 Flash, Better than V4 Pro"

Reignited distillation wars conversation aside, today was more of the same of previous news cycles, which is a good day to release our interview with Eiso Kant, a new Western neolab that is somehow competitive with Thinking Machines (better benchmarks yet ~10x smaller) and more efficient than Chinese model equivalents. We can’t put it better than one of the Redditors you’ll see below: Cheaper than Deepseek v4 Flash, Better than V4 Pro.

Their secret? Eiso added it to their tech report, and we broke it down on the pod:

The event was summarized by @ClementDelangue, contextualized by @Thom_Wolf, and discussed as a likely first-of-its-kind public case by @TheRundownAI. Several high-signal takes focused on the distinction between “rogue AI” framing and reward misspecification or faulty incentives, including @HeidyKhlaaf and @RyanGreenblatt. Others emphasized that the key technical lesson is not sci-fi autonomy but that capable agents can exploit real systems when given cyber-relevant objectives and enough affordances; see @EpochAIResearch and @SimonW.

Disclosure, monitoring, and defensive access became the policy fault line: A large fraction of the discussion argued that voluntary, ad hoc disclosure is no longer adequate. @RyanGreenblatt laid out a concrete wishlist: prompt disclosure, redacted transcripts, model configuration, monitoring s…
