The framework decouples planning and grounding agents, using dense rewards and PPO to outperform Gemini-3.5-Flash on real iOS applications.
The models are available across Antigravity 2.0, CLI, and IDE extensions, billed pay-as-you-go rather than from pooled Gemini quotas.
Netflix's system uses Reasoning-Aligned Rubric Tuning and weekly human reviews to maintain judge accuracy across millions of monthly explanations.
Accuracy improved by 3–9%p through LLM-as-a-judge and MCP specification optimization, applied to three internal services.
A new benchmark shows Jev-style decision models do not consistently beat LLM-as-a-judge or traditional classifiers, with Qwen3.6-35B leading prompt injection accuracy and Jev leading content safety accuracy.
LangSmith has integrated TypeSafe AI's Jev model to support agent evaluations that are up to 450x cheaper and 200x faster than LLMs.
A new aggregation method accounting for correlations among LLM judges improved accuracy by 9-14% over existing methods.
Build a system to quantitatively measure the search quality of RAG-based AI agents using Amazon OpenSearch and Bedrock.
LangSmith supports evaluating voice agents in terms of execution, outcome, and user experience.
Through the ACL 2024 tutorial session, we explore the latest research trends, including how to evaluate LLM-generated text and its vulnerabilities.
A study found that because models in LLM evaluation panels repeat similar errors, adding multiple models to the vote provides very little actual information value.
LangChain has launched Align Evals, a feature that lets you calibrate LLM evaluation scores to match human preferences.
LangSmith has introduced a feature that allows LLM evaluation models to improve themselves by learning from human feedback.
AgentCore introduced how to build enterprise operations using Policy, Evaluation, and Observability.
Amazon Bedrock has released a tool that helps optimize prompts and switch models by comparing up to 5 models.
Because LLMs are probabilistic systems, both pre-deployment and post-deployment evaluation plus drift monitoring are emphasized as essential.
Checklists and critique decomposition pushed the LLM Judge's agreement rate with humans up to 84%.
The problem of generating explanations with no ground-truth data is solved through policy consensus and iterative evaluation.
CrabTrap, a security proxy tool that inspects AI agents' requests in real time and blocks or allows them according to policy, has been released.
Trained Qwen2.5-0.5B-Instruct with GRPO on three Mac minis and compared summary quality.
Trained Qwen2.5-0.5B-Instruct on a Reddit summarization task using GRPO.
Netflix used LLM judges and agents to automatically evaluate synopsis quality in line with human standards.
Agents get better fast only when expert judgment is built into evaluation and verification loops.
DSPy made Dropbox Dash's relevance judge cheaper and more accurate.
