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.

Scientific Agent Skills is an open-source toolkit of 134 ready-to-use scientific domain skills for AI agents, covering cancer genomics, drug-target binding prediction, molecular dynamics, RNA velocity analysis, geospatial science, and time series forecasting. Each skill integrates with 78+ scientific databases and is backed by 70+ optimized Python packages, installable with a single npx command into agents like Claude Code, Cursor, or Codex. The core idea is separating scientific compute from the agent's reasoning loop. Instead of asking an LLM to hallucinate bioinformatics pipelines, you give it callable skills that actually connect to NCBI, PDB, ChEMBL, and other authoritative data sources. Optional cloud compute via Modal handles GPU-intensive workloads — molecular dynamics simulations, protein structure inference — without requiring local hardware. Forty-plus model integrations mean the skills layer is agent-agnostic. With 18.1k GitHub stars, this project is filling an obvious gap: the agent ecosystem has exploded in developer tools but scientific workflows have lagged behind. A bioinformatician can now wire up a Claude Code agent that genuinely queries gene expression databases, runs differential analysis, and interprets results — without writing custom integration code for each data source.
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.”
“The npx install pattern means I can wire 78 scientific databases into my agent in minutes. The Modal integration for GPU workloads is a thoughtful design decision — it keeps the local agent lightweight while offloading the heavy compute. This is exactly the kind of batteries-included toolkit the scientific computing community needs.”
“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.”
“Database integrations go stale fast — API endpoints change, authentication requirements shift, data formats get versioned. A 134-skill library is a massive maintenance burden for what appears to be a small team. Check the issue tracker before depending on this for anything publication-critical.”
“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.”
“This is accelerating AI-assisted drug discovery and genomics research by months. When an AI agent can natively call ChEMBL binding affinity data and run molecular docking simulations as skills, we've collapsed the distance between research hypothesis and computational validation. The implications for rare disease research are enormous.”
“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.”
“For science communicators and data journalists, this is a game-changer. Instead of waiting for a bioinformatician to run an analysis, you can point an agent at the skill library and get interactive cancer genomics visualizations yourself. The barrier to data-driven science storytelling just dropped significantly.”
