50 prompts per model (coding, writing, math, summarization, data analysis, customer support, translation, SQL, RAG and answering from documents, and agents and tool use), run on September 27, 2026. Ranked by how many prompts each model passed, then how many of the hard ones, then by the smaller message (the everyday models first), then by the lower cost per reply. No ranking is chosen by hand. Cost per reply is what OpenRouter charged us on average; in llmwise you pay per message.

Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.

Questions

Is llmwise's AI chat really free?

The trial is: 5 free messages, once, with no card. It doesn't refill; after it, a paid plan starts at $20 a month.

Can I chat without signing up?

Sometimes. We offer one message with no account to some visitors: if the box shows on this page, send it. GPT-6 Luna answers, with no files, tools or web search, up to 2,000 characters in and a reply of up to 800 tokens, one message per browser and 1 per network a day. Everyone can sign up for the 5 free messages.

Is there a free plan with no limits?

No. Every reply costs us money to make, so the free part is a fixed trial, and every limit is published instead of left vague.

Which free model is best?

In our test runs on September 27, 2026, DeepSeek V4.1 Flash passed the most prompts of the models in the free trial (49 of 50). GPT-6 Luna, which answers the free message, passed 47 of 50.

Does a long chat use more of the free messages?

Yes, a very long one: once the conversation passes 64k tokens, each reply counts as 2 messages; past 128k, as 4. The message box says so before you send.

Claude, GPT, Gemini, DeepSeek, Grok, Kimi, and GLM, in one chat.
