The Sequence Radar #889: Fable 5's Comeback, ZCode's Debut, Claude Science, and the $3.5B Deployment Land Grab
New models, agents and the evolution of the FDE landscape as the new battle field in AI.

TL;DR
- Fable 5 was redeployed after a temporary shutdown due to a jailbreak vulnerability, showcasing the need for robust compliance layers in AI deployment.
- Z.ai released ZCode, an agentic development environment built around GLM-5.2, offering a self-hostable alternative with a large context window.
- Anthropic launched Claude Science, a workbench designed to streamline AI workflows in scientific domains.
- Microsoft and AWS are making significant investments in forward-deployed engineering (FDE) teams and infrastructure, signaling a shift in AI's competitive landscape.
- The focus in AI is moving from model development to the integration, deployment, and runtime environments surrounding these models.
- New AI research includes SKILLOPT for optimizing agent skills, Nemotron-Labs-TwoTower for efficient diffusion language modeling, TUA-Bench for evaluating terminal agents, RLMF for uncertainty expression, SkillHone for continual skill evolution, and TabFM for zero-shot tabular data prediction.
