xAI: Grok Build 0.1
Analysis Summary
Grok Build 0.1 is an early-stage model from xAI, released May 2026. It supports text and image input with tool use, function calling, and a 256K token context window. No benchmark data is available, so reasoning, coding, and agentic capability cannot be assessed.
For businesses, this model should be treated as experimental. The xAI provider has a track record with the Grok family, but this specific variant has no published performance evidence. At $1 input and $2 output per million tokens, pricing is low, which may make it worth testing for cost-sensitive, lower-stakes tasks.
Do not adopt Grok Build 0.1 for production or client-facing workflows without first benchmarking it against your specific use cases. If performance proves adequate, the pricing is attractive for high-volume applications.
