Less than five months after its launch, French startup Bioptimus has announced the release of H-optimus-0, the world’s largest open-source AI foundation model for pathology. With 1.1 billion parameters, H-optimus-0 is trained on a proprietary dataset of several hundreds of millions of images extracted from over 500,000 histopathology slides across 4,000 clinical practices. This sets a new benchmark for state-of-the-art performance in several critical medical diagnostic tasks, from identifying cancerous cells to detecting genetic abnormalities in the tumor.

Rodolphe Jenatton, CTO of Bioptimus: “Having launched less than five months ago, we are excited to introduce H-optimus-0, a fully open-source model that represents a significant leap forward in the field of pathology. We are committed to advancing medical research and improving patient care. By encouraging collaboration and the adoption of new practices, we aim to speed up innovations in pathology and beyond, ultimately benefiting patients worldwide.”

Pathology is the cornerstone of disease diagnosis, requiring meticulous examination of tissue samples to identify abnormalities. Traditionally, this process relies heavily on pathologists' expertise and experience. However, the increasing complexity and volume of cases necessitate advanced tools that can assist pathologists in making faster, more accurate diagnoses.

H-optimus-0 Key Features and Capabilities

  • Unmatched Scale and Performance: With 1.1 billion parameters, H-optimus-0 is the largest open-source AI model tailored specifically for pathology, ensuring comprehensive analysis and high accuracy.
  • Extensive Training Dataset: Trained on a vast dataset of over 500,000 pathology slides, H-optimus-0 has been exposed to a diverse array of cases, enabling it to generalize effectively across different diagnostic scenarios.
  • State-of-the-Art Diagnostics: H-optimus-0 achieves state-of-the-art performance in several key diagnostics tasks, consistently meeting the performance or outperforming existing models and setting new standards in the field. The model was assessed on 5 tile-level tasks to identify tissue types or tissue characteristics and 6 slide-level tasks to detect the presence of biomarkers or the presence of metastasis across several cancer types.
  • Open Source Availability: As an open-source model, H-optimus-0 can be utilized by researchers to accelerate the development of novel digital pathology models and will foster collaboration among researchers, clinicians, and developers, driving further advancements and solutions in pathology AI.

With its unprecedented scale and depth of training within the open-source community, H-optimus-0 leverages cutting-edge AI technology to enhance the precision and efficiency of pathology diagnostics.

Professor Jean-Philippe Vert, PhD, co-founder and CEO of Bioptimus, said: “H-optimus-0 is just the beginning. It marks the first in a long series of models we will create at Bioptimus, each more advanced and comprehensive than the last. Future models will not only be trained on an even larger number of pathology images from Europe, Asia and Africa but will also incorporate other modalities, such as genomics and proteomics. Our ultimate goal is to create the first multiscale foundation model of biology, capable of integrating diverse biological data and scales to enable scientific discoveries and accelerate biomedical innovations.”

International human rights lawyer Jared Genser and Lanny J. Davis, who has close ties to two former US presidents and a worldwide reputation for defending those under attack with lies and smears, and for repairing the damage done to their reputations, have joined the legal and advocacy team supporting Cambodian businessman Yim Leak, Seiden Law LLP, which serves as Yim Leak's chief global counsel, announced today. Their first move is to hold the Thai government accountable, framing its conduct as either complicit in or willfully blind to a sustained smear campaign against Yim. Genser is Managing Director of Perseus Strategies, an international law firm. Over more than two decades, he has served as pro bono counsel to five Nobel Peace Prize laureates. The New York Times has referred to him as "The Extractor" for his work freeing political prisoners worldwide. Genser's decision to support Yim Leak's team comes as the businessman faces an asset freeze exceeding 20 billion baht (more than U

Corcept Announces CHMP Opinion Recommending EU Marketing Authorization for Lifyorli ® (Relacorilant)18.9.2026 15:00:00 EEST | Press release

Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, today announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that the European Commission (EC) should approve relacorilant, combined with the chemotherapy drug nab-paclitaxel, for the treatment of patients with platinum-resistant ovarian cancer. The CHMP’s recommendation is based on positive data from Corcept’s Phase 2 and pivotal Phase 3 ROSELLA trials, in which patients receiving relacorilant combined with nab-paclitaxel experienced improved progression-free and overall survival compared to patients who received nab-paclitaxel alone. The safety profile of relacorilant plus nab-paclitaxel in these trials was consistent with the safety profile of nab-paclitaxel monoth
