SandboxAQ’s AQCat Now Available on Claude via MCP
SandboxAQ announced that AQCat is now generally available on Claude Science through the Model Context Protocol (MCP), enabling researchers to access the company’s Large Quantitative Model (LQM) for materials-physics predictions via plain-language prompts. AQCat performs adsorption-energy calculations—critical for catalyst screening—with near-DFT accuracy while running thousands to up to 20,000 times faster than traditional methods. The model is spin-aware (accounts for magnetic behavior) and was trained on the public AQCat25 dataset containing 13.5 million high-fidelity DFT calculations across 47,000 intermediate-catalyst systems. The release aims to let teams pre-screen large catalyst design spaces at scale without coding, accelerating research for applications such as green hydrogen, sustainable aviation fuel, fertilizer production, and plastics recycling.
A technical release expanding a domain-specific LLM capability (materials science catalyst screening) broadens LLM use cases and researcher access but has limited direct impact on core AdTech/MarTech operations.

SandboxAQ Integrates Drug-Discovery Models into Claude
SandboxAQ has partnered with Anthropic to integrate its scientific AI models into Claude, enabling access to the company’s large quantitative models (LQMs) via a conversational interface without specialized infrastructure. SandboxAQ’s LQMs are described as physics-grounded models capable of quantum chemistry calculations and simulations of molecular dynamics and microkinetics, letting researchers evaluate candidate molecules before lab experiments. Founded as an Alphabet spinout about five years ago, SandboxAQ lists Eric Schmidt as its chairman and has raised more than $950 million. Nadia Harhen, SandboxAQ’s general manager of AI simulation, said the integration lowers the access barrier for computational and experimental scientists at pharmaceutical and industrial companies who previously needed dedicated compute to run the models.
Anthropic launches Claude Science AI workbench
Anthropic launched Claude Science on 2026-06-30, an AI workbench designed to give scientists a single environment for computational research by connecting databases, pipelines and tools. Anthropic says Claude Science is not a new model; it runs existing Claude models (including Claude Opus 4.8) without special access. The platform provides a main AI assistant that creates sub‑assistants, connects to more than 60 scientific databases, and includes pre-built toolkits for genomics, protein structure and chemistry. It includes a built-in fact-checker and saves reproducible artifacts by bundling figures with the exact code and environment that produced them. Claude Science can run on a lab’s own infrastructure and is available in beta to Pro, Max, Team and Enterprise subscribers. Anthropic is also funding up to 50 projects with awards of up to $30,000 each.
User Migrates AI Assistant from Claude to Qwen and Gemma
Anthropic has ended free use of Openclaw via Claude Code subscriptions and moved access to a separate pay‑as‑you‑go billing option, saying use of Claude subscriptions with third‑party agent tools violates company policy and excessively strains capacity. The restriction starts with Openclaw and will be extended to other third‑party tools. Openclaw, an open‑source agent tool released in November 2025 by developer Peter Steinberger, reached roughly two million users and ~150,000 GitHub stars within a week. Anthropic (Boris Cherny / Claude Code team) framed the change as capacity and policy enforcement and offered refunds to subscribers who do not accept the new terms. Steinberger (now at OpenAI) and Openclaw board member Dave Morin criticized the move. Reports note some users can switch Openclaw to OpenAI/ChatGPT‑Plus via OAuth to avoid separate API charges, but those integrations also have usage limits.
