Grok Build 0.1: Intelligence, Performance and Price Analysis

Grok Build 0.1, SpaceXAI's June 2026 model, ranks #70 in intelligence with above-average performance and competitive pricing ($1.00 per 1M input tokens, $2.00 per output tokens), but operates slower than average at 63 tokens per second and produces excessively verbose outputs. The model supports text and image inputs with a 256k token context window, though SpaceXAI has since released the newer Grok 4.5 (high) model as a replacement.
