Grok 4.7 vs Sonar
Side-by-side specs, pricing and capabilities. Both models run on Clade under one subscription, so you can switch between them in the same conversation.
Grok 4.7 comes from xAI and Sonar from Perplexity. The practical difference for most people is context, price, and which input types each one accepts.
Grok 4.7 holds more in a single conversation — 500K tokens against 128K — which matters for long documents and large codebases.
Sonar is the cheaper of the two on input tokens at $1.00 / 1M tokens.
