Model Routing Is Simple. Until It Isn’t.
The article challenges conventional model routing approaches by demonstrating that effective routing requires multi-objective optimization across cost, latency, and quality, rather than simple model classification. Through empirical analysis of 417 tasks on the AppWorld Test Challenge using CodeAct agents, the authors reveal that caching behavior, infrastructure state, and compliance constraints significantly impact performance metrics. Their optimization-based router achieves a 21% cost reduction and 9% latency improvement versus baseline approaches while maintaining 84% accuracy, with only 6ms overhead per task.

Welcome Inkling by Thinking Machines
Thinking Machines Lab introduces Inkling, a 975B-parameter multimodal Mixture-of-Experts (MoE) model with native support for text, image, and audio inputs, featuring a 1M-token context window. The architecture employs hybrid attention (5:1 sliding-window-to-global ratio), relative positional encoding, and short 1D convolutions, with 256 experts (41B active parameters). Trained on 45T multimodal tokens, it achieves efficient inference via NVFP4 quantization (600GB VRAM) and supports deployment in transformers, vLLM, and SGLang. Initial benchmarks demonstrate cross-modal reasoning capabilities, though video performance remains unevaluated.

Introducing Real World VoiceEQ: Measuring the human quality of voice AI
The Real World VoiceEQ benchmark introduces a comprehensive framework for evaluating human-like qualities in voice AI systems, addressing limitations of traditional metrics like word error rate. Developed from over 1 million human ratings across 15+ dimensions, it assesses Automatic Speech Recognition (ASR), Text-to-Speech (TTS), and Speech-to-Speech (S2S) models on paralinguistic features such as emotion, tone, and speaker consistency. Results reveal significant performance variation across models, with no single system excelling in all capabilities. The benchmark highlights gaps in handling accented speech, background noise, and emotional cues, emphasizing the need for specialized evaluations beyond automated metrics.
