Grok Build 0.1 is presented by third-party routing platforms under the xAI umbrella, with dedicated listing pages on OpenRouter and Atlas Cloud both attributing the model to XAI rather than to a separate hosting provider. The OpenRouter page (titled "Grok Build 0.1 - API Pricing & Benchmarks") and the Atlas Cloud page (titled "Grok Build 0.1 API by XAI") confirm a consistent slug and a shared identity, suggesting the model is part of the broader Grok family of large language models being made available to developers through unified API gateways that abstract away the underlying infrastructure.

Because the listings are surfaced alongside general LLM catalogs on multi-model platforms, Grok Build 0.1 appears to be positioned as a general-purpose conversational and reasoning model rather than a narrowly specialized system, fitting the typical role of Grok-family releases that aim to compete across chat, coding, and instruction-following workloads. The fact that Atlas Cloud frames it with "Competitive Pricing" and OpenRouter frames it with "Pricing & Benchmarks" indicates it is treated as a mainstream, benchmark-evaluated offering rather than an experimental preview, making it suitable for developers who want access to a Grok-line model through flexible API routing while retaining standard interface expectations.
