It scores 0.4581 NDCG@10 on decontaminated BEIR before fine-tuning and 0.4749 after fine-tuning, compared with 0.4334 for`sentence-transformers/static-retrieval-mrl-en-v1`. - Static models are unusually forgiving quantization targets. ... 来源：Exa MCP。Exa MCP public search metadata via the Agent Reach documented route; no cookies, login state, or full article body stored.

Fable 5 users will now experience many fewer “fallbacks”—where the system switches to a less capable model after they make a biology-related query. In our testing, this update reduced biology-related fallbacks by about 85% across our product surfaces. 1 Fable 5 will thus be able to assist with a wider range of biology tasks. In practice, users should see far fewer fallbacks on everyday health and educational questions—for example, interpreting lab results, understanding symptoms, and learning about biology in an educational context... 来源：RSSHub。RSSHub public RSS metadata only; no full article body stored.

Our latest internal evaluations of Astra, one of our upcoming models, over the past few days indicate significant advancements in agentic coding and cybersecurity. These results, in addition to expert assessments, have led us to conclude last night that we cannot rule out critical cy... 来源：RSSHub。RSSHub public RSS metadata only; no full article body stored.
