Deep Learning Weekly: Issue 463
Deep Learning Weekly Miko Planas ● Covered by 7 sources
This issue of Deep Learning Weekly covers recent AI model releases including xAI's Grok 4.5, OpenAI's GPT-Live voice model, and Mistral's open-sourced Leanstral 1.5, alongside developments in agentic AI systems and data infrastructure. Grok 4.5 achieves 80 tokens per second throughput and costs $2/$6 per million input/output tokens, while Leanstral 1.5 solves 587 out of 672 problems on PutnamBench. The newsletter highlights shifts toward agentic workloads requiring redesigned data systems, improved model interpretability through structural reasoning benchmarks, and engineering practices for optimizing AI agent efficiency and cost.
