Astera Labs, Inc. (NASDAQ: ALAB) is a semiconductor company building purpose-built connectivity solutions for rack-scale AI and cloud infrastructure. Its Intelligent Connectivity Platform spans the Aries PCIe/CXL Smart DSP Retimers, Smart Cable Modules and Smart Gearboxes, the Taurus Ethernet Smart Retimers and Smart Redrivers, the Leo CXL Smart Memory Controllers, and the Scorpio Smart Fabric Switches, all managed by COSMOS (COnnectivity System Management and Optimization Software). COSMOS is the software layer of the platform: firmware modules on the devices plus platform-level libraries that run on hosts and baseboard management controllers, exposing what Astera Labs describes as a single standardized API for device discovery, configuration, security attestation, firmware update, telemetry, link diagnostics, RAS testing, scripting and fleet management. That API surface is an on-premises host/BMC SDK rather than a public web API: the COSMOS Developer Kit is offered through a "Contact Us" motion and the supporting application notes are released through a document-request form, so no public API reference or machine-readable specification is published.
