arXiv 2607.15314 from actAVA AI covers patient consultation, multimodal clinical reasoning, interactive diagnosis and EHR tool use in one model. The training method generalizes past medicine: agents plan targeted capability improvements, train, evaluate, and refine data from observed failures, explicitly so gains in one area don't degrade another. That regression-prevention framing is the piece most fine-tuning pipelines skip and then get bitten by.

Agents gather heterogeneous data incrementally and make sequential, irreversible decisions under uncertainty, mirroring how physicians actually work (arXiv). Static multiple-choice benchmarks can't probe this. If you're building healthcare agents, this is the harness that test...
arXiv 2607.25886 isolates data-centric research capability by fixing the entire post-training stack so only the agent's data strategy varies. Four frontier agents across six benchmarks. Among searches that continued past the best observed score, 78.26% ended on a lower-scoring...
Microsoft's July 23 release targets a genuine gap: harness-based agents like Claude Code and Codex drive multi-turn reasoning, tool use, and external system access but were hard to train end-to-end with standard open RL infrastructure. The trick is decoupling training from inf...
A June 25 paper (arXiv:2606.25899) argues manipulation capability varies sharply by task rather than being one measurable scalar. (arXiv) That complicates any safety eval trying to score persuasion as a global number. For anyone deploying agents, the practical implication is t...
Addresses the fundamental privacy dilemma: cloud models need data access but enterprises can't share sensitive information. Splits execution between enterprise-side privacy agents and cloud-side capability agents. Directly relevant to AWS AgentCore and enterprise adoption. arX...
ECP captures agent outputs, tool invocations, and audit context uniformly, with adapters for LangChain, LlamaIndex, CrewAI, and PydanticAI so the same checks run against any of them. arXiv The authors explicitly label it work-in-progress with the method set expected to change....
