Free LLM API · OpenAI-compatible · 27 providers

All the free LLMs. One API.

Take a free key and call Llama, Gemini, DeepSeek, Qwen and more through one OpenAI-compatible endpoint. When a provider is busy, the router fails over to the next one. Your request just answers.

Quickstart

Point your SDK here.

Anything that speaks the OpenAI Chat Completions API works. Set the base_url, paste your key, done. Get a key →

curl https://dreamprompting.com/api/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "auto",
    "messages": [{"role":"user","content":"Hello!"}]
  }'

Pin a model with "model": "groq/openai/gpt-oss-120b", or use "auto" to let the router pick and fail over. Streaming works: pass "stream": true or the SDK's stream=True. List everything at /api/v1/models.

Routing

The route table

Requests try live providers in order and fail over on errors or rate limits. Free tiers first, trial credits next, keyless ch.at as the always-on last resort.

Models

Popular models at $0

DreamPrompting is a free, OpenAI-compatible LLM API and a drop-in free alternative to the ChatGPT and OpenAI API. Because it speaks the standard chat completions format, you can call popular open and GPT-class models for free: chat, coding, summarization, extraction and content generation, all from one endpoint with one free key.

Free ChatGPT / GPT alternative

GPT-class and GPT-OSS models through an OpenAI-compatible endpoint. Swap one base URL, keep your code.

openai/gpt-oss-120b

Free Llama 3.3 API

Meta Llama 3.3 70B and Llama 3.1, served through NVIDIA NIM and Cloudflare Workers AI.

nvidia/meta/llama-3.3-70b-instruct

Free Gemini API

Google Gemini Flash and Gemma through the free Google AI Studio tier, with thinking control.

google/gemini-3.1-flash-lite

Free DeepSeek API

DeepSeek V3 and reasoning models for coding and complex tasks, at no cost.

nvidia/deepseek-ai/deepseek-v4-pro

Free Qwen & Mistral API

Qwen 2.5, Mistral and Codestral for multilingual chat and code generation.

One key, automatic failover

If a provider is busy or rate-limited, the router moves to the next. Your app keeps working.

Announced Anthropic, August 2026

Claude now marks its AI-generated content

Anthropic has started embedding an imperceptible watermark into text Claude generates, and attaching signed C2PA provenance metadata to files such as .svg, .png and .jpg. It applies everywhere Claude is used, including the API and Claude Code. Models launched in the EU on or after 2 August 2026 support it at launch, and existing models are described as in progress.

Source: How Claude marks AI-generated content

What our API does remove

  • Zero-width characters and joiners
  • Bidirectional overrides (CVE-2021-42574)
  • Unicode tag payloads, decoded back to ASCII
  • No-break and other exotic whitespace
  • Variation selectors, soft hyphens, BOMs

Every removal reported by codepoint and line, on output from any model.

What it does not remove

Claude's text watermark. Anthropic does not publish the algorithm, but the behaviour it describes, surviving copy and paste while fading when text is heavily edited, paraphrased or translated, is characteristic of a token-level scheme rather than hidden characters.

Nothing is inserted, so nothing can be deleted. Our scanner will report a file as clean and the mark will still be there. The same is true of C2PA metadata on images, which this tool does not touch at all.

We would rather tell you that here than take the signup.

There is still plenty worth catching

Paste a file and see the zero-width characters, bidirectional overrides and smuggled tag payloads that really are in it, each one reported by codepoint and line. Free, and it works on output from any model.

Free tool, sign in to scan

See what is hiding in your code

Zero-width characters, bidirectional overrides that make source display in one order and compile in another, and Unicode tag characters carrying a payload that renders as nothing. Every removal is reported by codepoint and line, so you can check the change instead of trusting it.

Watermark remover

Works with every model

The scan reads characters, not providers, so ChatGPT, Claude, Gemini, Copilot and anything after them go through one pass with nothing to configure. Smuggled Unicode tag payloads are decoded back to readable ASCII rather than merely counted.

We measured it, 2026-08-12

code-generation calls 68

Raw model output is clean. The characters get added by the path your code travels, which is usually a browser.

Work out the cost before you pay it

Four calculators built on real data, not rules of thumb: a live BPE tokenizer, plus architecture figures for 63 open-weight models and 34 cards. Nothing to install, no account needed.

Token calculator

What a request really costs

Paste any text and watch it split into real tokens. See why output costs about five times input, why turn 20 of a conversation costs three times turn 1, and why the same sentence costs nearly double in Swahili.

Tokenize something →
English 8
Swahili 15

Same sentence, same meaning. 1.9x the tokens.

FAQ

Questions

Is there a truly free LLM API?

Yes. DreamPrompting is free to start with no credit card. Create a free account, get an API key, and it routes your request across the free tiers of many providers, returning a standard OpenAI-style chat completion.

Can I use this as a free ChatGPT or GPT API alternative?

Yes. The endpoint is OpenAI-compatible, so it is a drop-in free alternative to the ChatGPT and OpenAI API. Point the OpenAI SDK at our base URL to reach GPT-class and open models like Llama 3.3, Gemini, DeepSeek, Qwen and Mistral.

Which free LLM models are supported?

Popular models including Llama 3.3 70B, Google Gemini, DeepSeek, Qwen, Mistral, Cohere Command and GPT-OSS, served through Groq, Cerebras, NVIDIA NIM, OpenRouter, Google AI Studio and more.
