Grok 4.1 Fast - API Pricing & Benchmarks

Grok 4.1 Fast is xAI's best agentic tool calling model that shines in real-world use cases like customer support and deep research. $0.20 per milli...

Good cost/benefit for agent development. Using this in my openclaw main for building nostr ingesting / analysis daemons. Opus is crazy expensive. I use my grok browser in conversation mode to develop and revise a project plan then spit out a project plan and preceding prompt in a markdown code block for pasting into tui. Really love how you can interrupt grok in conversation mode and pivot it immediately. A clean plan saves on reasoning tokens. I like that grok stages in diffs and backup folders. Tell it to use main agent if you want it to handle deployment to avoid sub agent permission issues. A project that cost me 12$ to finish on google/gemini-3.1-pro-preview cost $0.5 with Grok.
