Shelf-life prediction with Arrhenius: from weeks of data to a shelf-life estimate in minutes

From a few weeks of accelerated stability data to a shelf-life estimate in minutes: on an amoxicillin example. Why the limiting parameter is not assay. And why the tool itself tells you when not to rely on extrapolation alone.

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.

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.

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.

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.

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.

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.

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.
