ChatGPT vs Claude vs Gemini vs Grok
On llmwise Pro, GPT-6 Sol up to 125 messages a month, Claude Sonnet 5.5 up to 125, Gemini 3.1 Pro (preview) up to 125, and Grok 4.7 up to 250. ChatGPT is OpenAI's own app for its GPT models; llmwise has GPT models in its own chat, not ChatGPT itself. We ran the same 50 prompts across 10 jobs on every GPT, Claude, Gemini, and Grok model and published every reply: each job with the families' picks ranked, then each one's own subscription.
Based on 550 of our test runs on , through OpenRouter with the app's own prompt and settings. Updated .
Short answer
In our test runs on September 28, 2026, the same 50 prompts across 10 jobs: GPT's 3 models passed 140 of 150 replies, Claude's 5 models passed 230 of 250 replies, Gemini's 2 models passed 95 of 100 replies, and Grok's one model passed 47 of 50 replies. Job by job, all 4 families' best models shared the top result on 8 of the 10 jobs; GPT's alone had it on writing; GPT's trailed on customer support; Claude's trailed on writing; Gemini's trailed on writing; Grok's trailed on writing and customer support.

Where your messages go
In llmwise, a message to GPT, Claude, or Gemini goes to the model's maker, or through OpenRouter when llmwise can't reach the maker directly. Grok models are served only through OpenRouter, by endpoints that don't store or train on prompts. The Privacy Policy has the details.
