Fylun Chat
Every model. One thread.
Fylun Chat is one conversation with every frontier model — GPT-5.6, Claude, Gemini, Grok, DeepSeek, Kimi, and 40+ more. Switch models mid-thread without losing context, dial reasoning up or down with each model's own controls, search the web with cited sources, and attach files the models can actually read.
FREE TIER — NO CREDIT CARD · ONE WALLET, EVERY SURFACE
Flagships, priced in the open.
49 chat models live right now, at provider list prices — this list renders from the same registry the picker does.
Every model keeps its own reasoning control — effort levels, thinking budgets, or adaptive toggles — mapped to the provider’s real parameters, not one fake global switch.
What's inside.
Every model, one thread
Switch from Claude to GPT to Gemini mid-conversation — the thread, files, and context carry over. Pick the right model per message instead of per subscription.
Per-model reasoning controls
Reasoning is a real control mapped to each provider's own parameters — effort levels for OpenAI, thinking budgets for Anthropic and Gemini — not a cosmetic global toggle.
Web search & deep research
Grounded answers with inline citations, and multi-step deep-research runs that read sources before writing — built into the same thread.
Files & vision
Attach PDFs, images, and documents. Models with vision read them directly; long documents stay available across the whole conversation.
Custom assistants
Save instructions as named assistants and reuse them across chat and embeds — the same assistant can answer on your site.
Day-0 catalog
New flagship models land in the picker the day providers ship them — no waiting for your one vendor to catch up.
What it retires.
Replaces ChatGPT Plus, Claude Pro, Gemini AI Pro, and Perplexity — every flagship in one thread, from one wallet.
Common questions.
Which models can I use in Fylun Chat?
50+ chat models across OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral, Moonshot, Alibaba, Zhipu, Cohere, Meta, and Perplexity — including each provider's current flagship. New models are added the day they ship.
Do I lose the conversation when I switch models?
No. The thread carries over — the new model sees the full conversation so far, including attachments. Switching is a picker selection, not a new chat.
How do reasoning controls work across different providers?
Each model declares its own control surface — OpenAI models take an effort level, Anthropic and Gemini models take a thinking budget or adaptive toggle — and Fylun maps your setting to the right parameter per model instead of pretending one toggle fits all.
How is this billed?
From one credit wallet at a flat, transparent markup over each provider's list price. No per-provider subscriptions, no API keys to manage.
