    Auto-labelling 1.2M robotics frames with VLMs: a failover story

    Two separate teams at Nexus Labs and Prophesee have adopted Bifrost, an open-source gateway, to manage their interactions with multiple large language models. Prophesee used Bifrost to caption 1.2 million robotics frames, achieving a 22% cost saving by intelligently routing requests across GPT-4o, Claude 3.7 Sonnet, and Gemini 2.5 Pro. Nexus Labs implemented Bifrost to improve the quality of their agent training data, finding that nearly half of their production traces were unusable due to inconsistent model behavior and hidden provider failures. By using Bifrost's advanced fallback and logging features, they were able to reduce corrupted traces from 17% to under 3%, enabling more reliable fine-tuning. AI

    IMPACT Bifrost's adoption by multiple teams highlights the growing need for robust infrastructure to manage LLM API costs and ensure data quality for agent development.

    Measuring AI Gateway Failover: 30 Days of Production Data

    Anthropic has released an update on Claude's sycophancy, noting that Opus 4.7 shows a 50% reduction in sycophantic responses compared to Opus 4.6, particularly in relationship guidance conversations. The company also detailed its election safeguards, emphasizing Claude's impartiality and accuracy in providing political information, with Opus 4.7 and Sonnet 4.6 scoring highly on evaluations. Additionally, Andrej Karpathy's 2025 review highlights Reinforcement Learning from Verifiable Rewards (RLVR) as a key advancement, enabling models to develop reasoning strategies and leading to AI
