Pathway has secured funding at a $500 million valuation, backed by Id4 Ventures, TQ Ventures, Red Bridge Ventures, Kadmos Capital, WS Investment Co, and Databricks chief AI scientist Jonathan Frankle. The company is challenging AI reasoning cost curves with its 150-million-parameter model.
Flinders University researchers evaluated two advanced reasoning large language models—o3-mini and DeepSeek-R1—and discovered they continue to reproduce racial and gender stereotypes when describing fictional patients with common medical conditions, despite being newer generation AI systems.
NVIDIA researchers have introduced Star Elastic, a post-training method that embeds multiple nested reasoning models at 30B, 23B, and 12B parameter scales inside a single checkpoint, enabling zero-shot model slicing without retraining.
US startup Arcee AI invested approximately half of its total venture capital to train Trinity-Large-Thinking, a 400 billion parameter open reasoning model designed to compete with Anthropic's Claude Opus in agent tasks.
Anthropic released Claude 3.7 Sonnet, its first hybrid reasoning model, while simultaneously experiencing its tenth service outage in 12 days and pausing token-based billing for its Agent SDK due to unexpectedly high costs for developers.
