Justify the worst-case marker of a shared facility in hours — not weeks

Cross-contamination risk assessment rethought: CovaSolv cleanability × CovaTox hazard surfaces the worst-case marker of a multi-product facility in hours instead of weeks. Why it is the combination, not a single axis — and why carbamazepine wins on the example roster, ahead of methotrexate and ethinylestradiol.

ICH M7 automated: mutagenicity triage in seconds — a Losartan worked example

ICH M7 requires two (Q)SAR methods per impurity. On a Losartan worked example: 10 impurities classified in seconds, 5 probable mutagens identified — including the well-known azido impurity (AZBT). How CovaTox covers both methods in one call, and where the limits are.

Can AI predict toxicity? The CovaTox benchmark — measured honestly

CovaTox covers 42 ADMET / toxicity endpoints in one suite. In a true same-split, same-metric head-to-head against the TDC leaderboard, we sit a few points below the best dataset-specialized models on the AUROC endpoints — with one pipeline across everything. We name the weak spots openly.

Agentic AI across the drug-development lifecycle, from discovery to scale-up

Agentic AI over MCP connects fragmented R&D data into one system. Example pipelines from discovery through CMC to manufacturing, and why the open tool layer decides the actual competitive edge.

Designing carbamazepine crystallization, three steps with CovaSolv

Solvent screening, cooling curve, anti-solvent. Why acetone dissolves more at both temperatures but ethanol gives the higher yield, and how water as an anti-solvent crashes solubility by a factor of 220 without cooling a single degree.

Context stuffing vs. tool calling: why many AI projects fail at the data architecture

More context does not make LLMs more reliable, the research shows the opposite. Three documented failure modes (lost in the middle, context rot, tool overload), why data architecture decides the outcome, and when tool calling is the more reliable choice.

RDKit over MCP: where the open-source toolkit stops, and where CovaSyn picks up

RDKit MCP servers give AI agents deterministic cheminformatics. Where the limit sits, no trained ML predictions, no hosting, no compliance, often too many generic tools, and what CovaSyn adds on top. With an honest recommendation for when a pure RDKit MCP server is enough.

Why LLMs fail at chemistry, and what the tokenizer has to do with it

LLMs fail at counting rings. The reason is not missing chemistry knowledge but the tokenizer: SMILES strings shatter into disconnected fragments, and the molecular graph is lost. What the research shows, and how validated tools solve the problem.

CovaSolv benchmarked: predicting solubility at R² 0.92, and why the honest number is the more important one

CovaSolv predicts logS at R² 0.92 and RMSE 0.64, on 5,315 unseen molecular scaffolds. 78 % of predictions sit within 0.5 log units of the measured value. How close that is to the physical noise floor, honestly explained.

Gemini 3.5 Flash on chemistry: from 14 % to 76 %, why the cheapest model makes the biggest jump

Gemini 3.5 Flash reaches just 14 % on molecular reasoning without tools. Attach CovaSyn MCP and the same model jumps to 76 %, a 5.5× lift, the largest of all tested frontier models. Why the cheapest model benefits most, what it costs, and where the lift is not yet perfect.

Improve Claude's Chemical AI Capabilities, Drug Discovery, Biologics, ICH M7 via MCP

Claude Haiku 4.5 reaches 21 percent on the ICLR 2026 chemistry benchmark. Attach the CovaSyn MCP server and it jumps to 85 percent. Same model, no fine-tuning, no prompt magic, just deterministic chemistry tools wired through the Model Context Protocol. This is the practical guide: how to wire it, what it unlocks for drug discovery and biologics, and the limits to know.

Data quality isn't the real bottleneck. Why 55 percent of biotech AI pilots actually fail.

In the Benchling Biotech AI Report 2026, 55 percent of 100 surveyed AI leaders name "poor data quality" as the top reason their pilots fail. The industry conclusion, "we need better data management", addresses the symptom, not the cause. A counter-thesis, three real failure modes, and a concrete proposal.

The AI Scientist meets MCP: what the three Nature papers from May 19, 2026 mean for deterministic chemistry tools

FutureHouse (Robin), Google DeepMind (Co-Scientist) and DeepMind (ERA) published simultaneously in Nature on May 19, 2026: AI systems now generate hypotheses, design experiments, and optimize scientific software end-to-end. What the papers don't quite say: without a deterministic, validated computation layer the loop bottlenecks on human review. That's where the Model Context Protocol fits in. A reading frame.

14 % → 92 %: How CovaSyn scores on the ICLR 2026 chemistry benchmark

Klambauer's lab (JKU Linz) built a molecular-reasoning benchmark for ICLR 2026 that tests real chemistry instead of using LLM judges. Four frontier LLMs score 14 to 41 percent on it. With CovaSyn MCP attached, the same models reach 76 to 92 percent, three of them above 85. Four models, 12,540 responses, the full numbers including the gaps.
