LWiAI Podcast: Sonnet 4.6, Deep‑Thinking Tokens, Anthropic–Pentagon
Episode 235 of the Last Week in AI podcast (recorded 2026-02-27, hosts Andrey Kurenkov and Jeremie Harris) summarizes major AI model releases, business and funding moves, infrastructure and geopolitics, research advances, and policy developments. Model and tool coverage includes Anthropic’s Sonnet 4.6 (1M-context, strong ARC-AGI-2 results), Google Gemini 3.1 Pro, xAI’s Grok 4.2 beta, Anthropic’s Claude Code Mobile “Remote Control,” and Perplexity’s multi-agent “Computer.” Business items include a reported Meta–AMD chip deal, MatX raising $500M for transformer chips, World Labs raising $1B, and a startup raising $100M to model human behavior. Infrastructure and geopolitics note Stargate data-center delays and China’s wafer-scaling plans. Research topics highlighted include masked updates in optimizers, “deep-thinking tokens,” attractor-state behaviors, mechanistic interpretability, mapping task difficulty to human time horizons, and security/policy items such as Anthropic–Pentagon tensions and reports on distillation attacks and efforts to disrupt malicious use.
Summarizes multiple major model releases, large funding rounds, infrastructure and policy tensions that affect AI capabilities and supply chains; useful as an aggregated industry update but not a single industry-shifting announcement.
