Modal

Modal made multi-node, RDMA-connected clusters globally available. The runtime also adds full-kernel VM sandboxes, sandbox sidecars, and sticky sessions that reconnect WebSockets to the same container.

Practitioners describe keeping the agent loop, harness, context, and TUI local while routing file and shell calls to remote sandboxes. Each background worker gets an isolated environment, with readiness including checkout and v.

Anthropic launched Claude Science in beta as a research app with traced artifacts, on-demand environments, and access to more than 60 scientific databases. Modal is already integrated as an elastic compute layer, giving researchers a single workspace for data access, code, and reproducible runs.

Step 3.7 Flash landed immediately across Kilo, Modal, SGLang, Hermes-linked tooling, and DesignArena as the model’s 198B MoE, 256K-context release spread through the stack. The breadth of day-one support gives engineers multiple ways to serve, benchmark, and wire the new open-weight multimodal model into agents.
