Bonjour à tous,

Nous organisons pour la première fois une journée de "Super meet up" avec des anciens speakers qui reviennent pour nous parler de leur dernières avancées. Cette journée aura lieu le 9 décembre au CNIT. Elle se déroule au sein de la conférence apidays où ils nous offrent une salle.

Bonne nouvelle : nous avons 80 places à offrir à la communauté via ce lien.

Pour assister à la conférence, il faut absolument prendre une place sur le site apidays. Le pass vous donne également droit au reste de la conférence les autres jours.

Pour les talks nous sommes très contents d'annoncer :

• AGO : Maxime Thoonsen Founder
• Partoo : Thibault Renouf CO-CEO
• Docker : David Gageot Senior Principal Software Engineer et Jean-Laurent de Morlhon VP Software Engineering
• Linkup : Boris Toledano COO

Quels que soient les secteurs ou les pays, un même défi se répète : des stratégies ambitieuses qui n’aboutissent pas aux résultats attendus. Le Global State of Strategy Execution Report, publié par OKR Mentors, analyse la façon dont plus de 200 organisations dans 30 pays transforment leur stratégie en résultats concrets. Grâce au Global Strategy Execution Maturity Index™, l’étude révèle ce qui distingue les 11 % de leaders en exécution stratégique, ceux qui dépassent systématiquement leurs objectifs. Alignement, rituels, responsabilisation, passage à l’échelle… Les données montrent là où la majorité des organisations échouent et ce que les meilleurs font différemment. Les leaders de l’exécution stratégique ont :

• 57 % dépassent leurs objectifs financiers,
• et 83 % d’entre eux vont plus vite que leurs concurrents.

Rejoignez Laurent Morisseau et Elie Casamitjana, CEO d’OKR Mentors, pour un décryptage approfondi de ces résultats et des bonnes pratiques pour une stratégie agile. Vous découvrirez également comment l’évaluation SEM360™ vous permet de mesurer la maturité d’exécution de votre organisation et d’identifier votre Persona en Exécution Stratégique.

Présentation du projet Bacthub par Laurence Watier: premiers résultats, méthodologie innovante fondée sur le chaînage sécurisé de données hospitalières et médico-administratives, applications concrètes pour la surveillance et la prévention de l’antibiorésistance en France, et temps d’échange sur les perspectives et les collaborations possibles.

LLM-based web agents have recently made significant progress, but much of it has occurred in closed-source systems, widening the gap with open-source alternatives. Progress has been held back by two key challenges: first, a narrow focus on single-step tasks that overlooks the complexity of multi-step web interactions; and second, the high compute costs required to post-train LLM-based web agents.

To address this, we present the first statistically grounded study on compute allocation for LLM web-agent post-training. Our approach uses a two-stage pipeline, training a Llama 3.1 8B or QWEN 2.5 7B student to imitate a Llama 3.3 70B teacher or QWEN 2.5 72B via supervised fine-tuning (SFT), followed by on-policy reinforcement learning (GRPO).

We find this process highly sensitive to hyperparameter choices, making exhaustive sweeps impractical. To spare others from expensive trial-and-error, we sample 1,370 configurations and use bootstrapping to estimate effective hyperparameters. Our results show that combining SFT with on-policy RL consistently outperforms either approach alone on both WorkArena and MiniWob++. Further, this strategy requires only 55% of the compute to match the peak performance of pure SFT on MiniWob++, effectively pushing the compute-performance Pareto frontier, and is the only strategy that can close the gap with closed-source models.

About the speaker

I’m Massimo Caccia, Senior Research Scientist at ServiceNow Research, specializing in post-training methods for computer-use agents. I see computer use as the ultimate playground for testing agents, thanks to its ubiquity and diversity. My research involves conducting large-scale empirical studies to systematically evaluate trade-offs among different approaches and to develop practical know-how, with reinforcement learning being a particular focus.

As a core contributor to the web-agent research library ecosystem, I actively shape evaluation frameworks (BrowserGym, WorkArena) and development platforms (AgentLab). My goal is to bridge foundational research and scalable tools to advance the field.

Previously, I completed my Ph.D. at the Quebec Artificial Intelligence Institute (Mila) under Professor Laurent Charlin. During my doctoral studies, I collaborated with DeepMind’s Continual Learning team led by Marc’Aurelio Ranzato, Amazon’s team under Alex Smola, and ElementAI prior to its integration with ServiceNow.

My Ph.D. research focused on building agents capable of accumulating and transferring knowledge across tasks, drawing from continual learning, transfer learning, and meta-learning. My work explored applications in language, vision, and reinforcement learning, emphasizing improvements in data and compute efficiency.
