Claude Opus 4.8 vs Grok 4.5
A business-first comparison of price, availability, coding fit, and compliance.
Claude Opus 4.8 is Anthropic's generally available value coder, priced at $5 input and $25 output per million tokens and powering Claude Code. xAI released Grok 4.5 on July 8, 2026 for coding, agentic tasks, and knowledge work, but has not published per-token pricing for it as of this writing.
Opus 4.8's predictable pricing and documented compliance make it the lower-risk pick for regulated workloads today. Grok 4.5's broader platform integrations, including Databricks and Amazon Bedrock, may appeal to teams already standardized on those platforms.
