Duck.ai models: Free, Plus and Pro access
Duck.ai is a multi-model interface, but model availability changes. This page structures the model facts and links users to alternatives with broader model control.
Duck.ai model access by tier
This table is written as a verification-friendly block. The exact model list should be rechecked before public indexing because DuckDuckGo updates models.
| Tier | Model access | Best use |
|---|---|---|
| Free | Claude Haiku, Mistral Small, OpenAI GPT mini/nano/oss models listed by DuckDuckGo | Best for quick private chat and everyday questions. |
| Plus | Additional advanced models such as GPT-5.4 and Claude Sonnet versions listed by DuckDuckGo | Better for heavier private AI chat without jumping to a standalone chatbot account. |
| Pro | Plus models plus Claude Opus access and higher reasoning effort where available | Better for demanding multi-step tasks and higher Duck.ai usage. |
Uploads and file limits
Duck.ai supports images and PDFs on supported models, but not spreadsheets.
Better alternatives if model control is the real need
Duck.ai gives easy access to a curated model set. Users who want more model choice should compare these.
Brave Leo
Best privacy/no-login browser AI match for Duck.ai users who care most about private quick chat.
Lumo by Proton
Strong privacy-brand alternative for private AI chat outside DuckDuckGo.
HuggingChat
Best open-model style alternative for Duck.ai users who want open-source model access.
Poe
Best multi-model hub when users want many bots/models in one app rather than Duck.ai simplicity.
Mistral Vibe / Le Chat
Strong free AI chat alternative built around Mistral models and creation/search workflows.
Perplexity
Better than Duck.ai for source-backed answers and research intent.
Andi Search
Private/ad-free AI search alternative for users comparing Duck.ai with answer engines.
You.com
Useful when AI search and search/API workflows matter more than no-login private chat.
OpenRouter
Best for users who want model choice through an API/router, not a private chat wrapper.
Ollama
Best local/private AI option for running models on your own machine.
LM Studio
Local desktop AI alternative for users who want model files and offline-style control.
Jan
Open-source local AI assistant alternative for privacy/control users.
Open WebUI
Self-hosted AI web UI for local/private chat setups, often used with Ollama.
Kagi Assistant
Paid privacy-search ecosystem alternative with assistant workflows.
How to explain Duck.ai models without becoming outdated
Duck.ai model pages need careful wording because model availability changes faster than normal software features. The safest public structure is to explain the tiers, show the latest verified model examples, and state that the official model picker is the final proof source before indexing.
For SEO, the key is not only the exact model names. The key is the user’s model-control problem. Some users want easy access to a few popular models privately. Some want a huge catalog. Some want open-source models. Some want to run a model locally. Some want an API/router. Duck.ai is strong for curated private hosted chat, but weaker for complete model control.
Model-control alternatives
If the user wants more model choice, Poe and OpenRouter are better comparison targets. If the user wants open-source model discovery, HuggingChat matters. If the user wants local/private inference, Ollama, LM Studio and Jan should be linked. If the user wants a self-hosted interface, Open WebUI should be ranked high. If the user wants mainstream model quality with workspace tools, ChatGPT, Claude and Gemini still belong in the comparison.
Model decision checklist
- Does the user need no account or simply fewer accounts?
- Does the user need model choice or model privacy?
- Does the user need upload support?
- Does the user need images, PDFs or spreadsheets?
- Does the user need local/private inference?
- Does the user need API access?

Duck.ai models FAQ
Does Duck.ai use only one model?
No. Duck.ai is a multi-model interface, but the exact available models depend on current DuckDuckGo support and the user’s plan.
Can Duck.ai replace OpenRouter?
No. OpenRouter is a model/API router for broader model access. Duck.ai is better as a simple private chat interface.
Can Duck.ai replace Ollama?
No. Ollama is for local model running. Duck.ai is hosted, so users who need local-only control should compare local tools.
Does Duck.ai support spreadsheets?
No. v32 data marks spreadsheet upload as not supported, while PDFs/images are supported on some models with limits.
