SpaceXAI: Grok Build 0.1 (x-ai/grok-build-0.1) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for SpaceXAI: Grok Build 0.1: Activate ephemeral prefix caching to slash input costs by 50% (down to $0.5/1M) or route via asynchronous Batch API for 50% off standard token rates.
OpenAI & Microsoft Founders Hub ($2,500–$150,000 Credits) + 50% Batch API Discount
OpenAI GPT-6.1 Sol ($2/$10 base rate) qualifies for immediate 75% automatic prefix caching ($0.50/1M), 50% off 24-hour Batch API completions ($1/$5), and up to $150,000 in OpenAI/Azure Foundry credits via Microsoft for Startups Founders Hub (no VC funding required for initial tiers).
In Etuki October 2026 FinOps telemetry comparing SpaceXAI: Grok Build 0.1 (API ID: x-ai/grok-build-0.1) vs OpenAI GPT-6.1 Sol (API ID: gpt-6.1-sol), SpaceXAI: Grok Build 0.1 offers lower standard input pricing at $1/1M tokens ($2/1M output), while SpaceXAI: Grok Build 0.1 leads in cached prefix economics at $0.5/1M tokens (50% discount). OpenAI GPT-6.1 Sol achieves a 10ms faster P90 time-to-first-token latency (270ms vs 280ms).
Auto-discovered via live global telemetry registry.
Context Cliff Alert: Prompts exceeding 272K tokens double in price from $2/$10 to $4/$15 per 1M tokens.
