FREE AI.PAID BY ADS.

AdFreeLLM is a public AI terminal. You open the chat page, pick one of five real models, and type — there is no account form, no email verification, no password, and no card field anywhere in the product. The machine treats every visitor as a guest, the way a payphone or a public bench does.

The models are real and they are named honestly. When the board says DeepSeek V4 Flash, DeepSeek V4 Flash is what answers you; we never quietly route a request to something cheaper and keep the label. Answers stream back token by token from a live backend, with Markdown, tables, fenced code and LaTeX rendered inline.

Every free service is paid for somehow; the only real question is whether you can see the mechanism. Here you can. After an answer finishes, one clearly labeled sponsored card may appear in the conversation — matched to the topic you asked about, never interrupting mid-answer, and never more than one per answer. Advertisers pay for that placement, and that payment is what covers the GPU time your question just burned.

Because our payer is the advertiser rather than you, the entire account apparatus becomes unnecessary. No accounts means no registration funnel, no upsell email sequence, no quota meter tied to an identity, and no login wall between you and the first answer. There is no premium tier, no token store, and no checkout page anywhere on this site — not hidden, not planned.

Which ad appears is decided server-side by a small model reading your question. When the question involves grief, medical or mental-health distress, self-harm, violence, or a child's safety, no ad is sent at all. An ad in those moments would be predatory, and no amount of revenue makes that a good trade.

Gemini 3.6 Flash is the default: fast and general, the right pick for everyday questions, drafting, and quick explanations. DeepSeek V4 Flash is the one to choose for reasoning and code. Gemini 3.5 Flash Lite is the lightest and fastest when you want an answer more than you want depth. GLM 5.2 has the strongest bilingual footing — Chinese prompts, mixed-language questions, and translation that keeps its register — and in our sampling it was also the most reliable machine on the board. Gemma 4 31B is the open-weights option for anyone who prefers talking to an openly released model.

Those characterizations come from running the models, not from reading their marketing. So does the least flattering one: in end-to-end sampling on 2026-08-13, Gemma 4 31B failed roughly half its calls while GLM 5.2 answered every attempt in about 725 milliseconds. We list Gemma anyway, labeled as the least stable of the five, because hiding a working-but-flaky option serves nobody.

The terminal is not the only way in. The same backend is exposed as an OpenAI-compatible chat completions API: point any OpenAI SDK at our base URL, click once for a key, and stream. Minting a key takes one HTTP request with no signup and no email — the same bargain as the web chat, and the same sponsored block appended to each answer to pay for it.

Structured consumers are protected rather than broken. Requests using JSON mode, tool definitions, or tool_choice are passed through completely untouched, because injecting an ad into machine-consumed output would simply corrupt your program. Multi-turn is safe too: hand the previous answer back exactly as you received it, ad block included, and the gateway strips it before the model ever sees it — so ads never pollute your context or cost you prompt tokens.

Free and shared has real costs, and we would rather state them than have you discover them. The machines are shared, so each IP is limited to roughly 6 messages per minute. A free API key is good for about 500 short requests per day, and the site-wide number of new keys issued each day is tuned automatically from measured upstream health — when the pool struggles, issuance shrinks the same night.

There is no SLA. The capacity behind these models is free capacity, so occasional errors are expected and callers should retry; this does not belong on a production critical path. We publish no invented review scores, no user counts, and no testimonials. Because there is no account system there is also no stored profile or email tied to your conversations — but we will not dress that up as a privacy feature we engineered, because it is simply a consequence of not needing accounts.

Most people arrive here already using something else, and the honest comparison is narrow rather than sweeping. The official channels — the ChatGPT free tier, DeepSeek's own app, Google's Gemini app — are capable products with real engineering behind them, and each one asks you to sign in before your first message. That is the difference worth measuring: not that we are better at inference, but that nothing stands between you and the first answer, and a labeled sponsored card is what pays for it instead of your account data or a subscription.
