Perplexity CEO shares early Gemini 4 Carbon evals: a record 0.857 on the WANDR deep-research benchmark at $5.86 per task, ahead of Argon and GPT-6 Astra
Perplexity CEO Aravind Srinivas posted early evals of Gemini 4 Carbon on X: it scored a record 0.857 on Perplexity's Wide-And-Deep-Research (WANDR) long-form research benchmark at $5.86 per task, versus 0.802 ($7.88) for Gemini 4 Argon and 0.735 ($13.34) for GPT-6 Astra. He called Carbon the strongest model Perplexity has seen for long-form research and answer quality, and said it will come to all Pro and Max users inside Perplexity Computer once there is enough token capacity.

X discussion: Anthropic's head of platform engineering says a team with no Rust developers had Claude port the whole Messages API to Rust, cutting CPU by roughly 40-50%
Katelyn Lesse, Anthropic's head of platform engineering, said on the Latent Space podcast (published Oct 27) that a Rust version of the Messages API fully rolled out the previous week. The old system was a CPU-hungry Python monolith, the team started with "not a single Rust developer", humans designed and verified the system, Claude wrote the implementation, and shadow traffic compared outputs between the old and new versions. Her ballpark figures are roughly 40-50% less CPU and 10-20% better time to first token. A clip posted by Somi (@somi_ai) drew 1,000+ likes and about 140K views on X and was quoted by swyx and others, with the debate centered on whether "never do the big rewrite" is now outdated advice. These are X discussion views and spoken estimates; Anthropic has not published a written engineering report.

X Discussion: Vercel CEO Guillermo Rauch Says "Own Your Intelligence," Urging Local Models to Keep Spreading and Developers to Own Their Agent Harness and Data
Vercel CEO Guillermo Rauch posted on X on November 1: "Own your intelligence. Anyone that opposes this has something to sell you (perhaps your own intelligence back to you.)" He argued that local models need to keep proliferating; since the biggest models may be out of reach locally for now, the best option is to keep your options open: own your harness, data, connections and runtime, meaning your agents, and embrace open source. Within about 12 hours the post drew about 2,500 likes, 128K views and over 100 quote posts, with debate centered on how to balance local and cloud AI.
