Does DeepSeek have a free tier?
No permanent free tier; new accounts occasionally get a small grant. The list price does the work: v4-flash input is $0.14/M on cache miss and $0.0028/M on cache hit (official pricing page is authoritative).
DeepSeek: get an API key and write fiction with it on your phone
The price-performance benchmark for long Chinese prose: V4 models carry a 1M context, and cache-hit input costs 1/50th of a cache miss — long chats and serial continuations get cheaper as they grow. This page is the BYOK quick answer for DeepSeek: key steps, direct console and pricing links, and the app-side notes that matter. Verified 2026-07-18.

What does it power inside Foreverse?
The factory preset declares 1 modality flag for DeepSeek. The models actually available come from the live catalog fetched in-app — catalogs move fast, and the flag only means the protocol wiring is ready.

How do I get a DeepSeek API key?
- Sign up at platform.deepseek.com with email or phone.
- Open API keys in the sidebar → create a key — it is shown exactly once, copy it immediately.
- Top up a small balance under billing. No monthly fee; usage draws from the balance per token, and prices are low enough that a small top-up lasts.
Key in hand: three steps to connect
- Open the app's Settings → AI models & services and find DeepSeek in the list (one of 62 presets, with logo and search).
- Paste the key and tap the connectivity test — it fires one real request to verify key and network, and pulls back the model list while it's at it.
- Enable the models you want, then set per-modality defaults (text, image, speech, and video each get their own); continuation, chat, and listening route through them from then on.
The one universal host pitfall: the API host must include its full version prefix (this provider's exact form is in the notes below) — the app never appends /v1 for you.
DeepSeek-specific notes
The preset host is https://api.deepseek.com/v1; an Anthropic-compatible form exists at https://api.deepseek.com/anthropic. Since July 2026, V4 doubles its price during Beijing peak hours (9:00–12:00, 14:00–18:00) and holds baseline otherwise — shift batch work off-peak. Prefix caching is automatic, and cache-hit tokens show in the app's request records.
FAQ
Where does the key live once I paste it into the app?
It's stored on your device only, under system-level encryption — never uploaded or synced to any Foreverse server. Requests go straight from your phone to the provider's official endpoint with zero markup. To revoke access, delete the key in the provider's console.
