AI-Scientist-v2 is Sakana AI's second-generation autonomous research system that generates scientific papers end-to-end — from hypothesis formation through experimentation, data analysis, and manuscript writing. It's historically notable for producing the first AI-authored workshop paper accepted through peer review. The v2 system removes reliance on human-authored templates that constrained the original, instead using a progressive agentic tree search guided by an experiment manager agent. This makes it more exploratory across ML domains, though Sakana acknowledges it trades v1's high template success rate for broader generalization with lower per-run success. Costs run roughly $20-25 per full research run using Claude 3.5 Sonnet. The system integrates with Semantic Scholar for literature review and supports OpenAI, Gemini, and Claude via AWS Bedrock. The custom license requires disclosure of AI use in resulting publications — a meaningful ethical constraint for a system that could otherwise flood conferences with AI-generated submissions.

Yahoo Scout is Yahoo's full-scale return to search, powered by Anthropic's Claude and grounded in both Yahoo's proprietary data and Microsoft Bing. Available at scout.yahoo.com and embedded across Yahoo News, Finance, Mail, and Search for ~250 million U.S. users. Every response includes inline citations designed to send traffic back to publishers — a deliberate move to rebuild the 'social contract' between search and journalism that Google AI Overviews fractured. Scout launched in January 2026 and has been rapidly expanding. It's notably different from ChatGPT Search in emphasizing source attribution over answer completeness.
Reviewer scorecard
“For ML research teams, the $20-25 per run cost to get a draft paper with experiments is genuinely interesting as an ideation tool. The tree search approach that explores multiple experimental directions in parallel is the kind of thing that would take a grad student weeks.”
“Yahoo Scout is a solid product but its distribution advantage — 250M users — is its only real differentiator over Perplexity or You.com. The Claude integration is good but doesn't do anything developers can't get from claude.ai directly. It's a consumer product, not a developer tool.”
“Sakana's own documentation says v2 has lower success rates than v1 and is 'more exploratory.' Paying $25 for a failed research run with no guarantee of a usable output isn't a workflow most researchers will adopt. The peer review acceptance was a workshop paper — the lowest bar in academic publishing.”
“Yahoo has tried multiple search relaunches over the past decade and none stuck. The Claude foundation is good but the search market is brutal — Perplexity has a head start, Google has scale, ChatGPT has stickiness. Citation-first positioning is a nice differentiator, but it's a values argument in a market that selects on answer quality.”
“This is the beginning of AI as a genuine research collaborator, not just a writing assistant. Within five years, AI-generated hypotheses tested by autonomous agents will be standard practice in computational fields. AI-Scientist-v2 is primitive version 0.2 of that future.”
“Publisher-first citations are the sustainable design principle for AI search that Google fumbled. Yahoo's scale means this choice actually moves dollars back to journalism at meaningful volume. Whether Scout succeeds or not, forcing that design convention into a mass-market product matters for the media ecosystem.”
“Science communication is a craft, and the idea of fully automating it makes me uncomfortable. The best papers are ones where researchers deeply understand and can defend every methodological choice — a system that writes the paper for you undermines that accountability.”
“The fact that Yahoo Scout sends traffic back to publishers is the most creator-friendly thing in AI search right now. Every AI answer that links to sources instead of absorbing them is revenue that flows to writers. It's not altruistic — it's embedded across Yahoo Finance and News — but the incentives are aligned in the right direction.”
