How to give DeepSeek live, up-to-date answers
The DeepSeek model has no live data of its own. The search toggle in the DeepSeek app runs server-side and isn't part of the model, and the open weights you run on Ollama or LM Studio are fully offline - so past its training cutoff, DeepSeek answers current questions from memory, often wrongly. To fix that you feed it live web context. Here's how, with measured proof it works.
Why DeepSeek gets current facts wrong
Two things are true of the DeepSeek model you actually run:
- It's frozen at its training cutoff. Like every model, it only knows what it was trained on. Ask about a release, a price, or an event after that date and it fills the gap with a confident guess.
- It has no live data of its own. The search toggle you may have seen in the DeepSeek app is a server-side feature; it isn't part of the model. And the open weights you download and run via Ollama or LM Studio have no web access at all, they run fully offline. Either way, current information is something you add.
Proof it works (measured)
We benchmarked DeepSeek-chat, the large cloud DeepSeek model with a big context window, on current-fact questions. On its own it got 0 of 5 correct, confidently wrong: "Tavily was acquired by Snowflake" (it was Nebius), "the current Python is 3.13.1" (stale), a wrong pricing tier. With a Grounder evidence pack in the prompt: 3 of 5.
Full method and the two remaining misses are on the benchmark page.
Running DeepSeek yourself? One extra thing to watch
If you run the open weights locally, everything above still applies: the model is offline and frozen, so it needs the same live-context step. The one addition: if you load a larger DeepSeek at a small context window to fit your VRAM, a full web page will overflow it and the model returns nothing. Keep the context you add token-capped.
Approach 1: an MCP server
If your client speaks MCP (LM Studio does), register a search server and DeepSeek can call web tools
itself. With Grounder, add one block to your MCP config (~/.lmstudio/mcp.json in LM Studio):
{
"mcpServers": {
"Grounder": {
"command": "uvx",
"args": ["grounder-mcp"],
"env": { "GROUNDER_API_KEY": "your_grounder_key" }
}
}
}
Now the model can call web_search, fetch, and deep_search and
answer from live sources instead of memory.
Approach 2: an API pipeline
If you drive DeepSeek over an API, do the retrieval yourself and put a token-capped pack in the prompt (that keeps you inside the window even on a small local build):
import requests
KEY = "your_grounder_key"
# 1. One call: search, read several pages, rank, return a pack capped to your window
pack = requests.post("https://grounder.dev/v1/deep_search",
headers={"Authorization": f"Bearer {KEY}"},
json={"query": "latest stable Node.js LTS version", "max_tokens": 600},
timeout=180).json()
# pack["passages"] are cited, ranked, and capped to your window - answer only from them
evidence = "\n\n".join(p["text"] for p in pack["passages"])
# 2. Hand the evidence to DeepSeek (Ollama shown; any OpenAI-compatible server works)
r = requests.post("http://localhost:11434/api/chat", json={
"model": "deepseek-r1",
"messages": [{"role": "user",
"content": f"Answer using only the evidence.\n\nEVIDENCE:\n{evidence}\n\nQuestion: ..."}],
"stream": False,
}).json()
print(r["message"]["content"])

Does DeepSeek know about recent events?
No. It's frozen at its training cutoff and has no live data of its own, so it answers current questions from memory (often wrongly) until you add a web-search step.
Does the DeepSeek model have web search built in?
The DeepSeek app has a server-side search toggle, but the open weights you run yourself via Ollama or LM Studio do not. You add search yourself, via an MCP server or an API pipeline.
How do I give DeepSeek current information?
Add live web context: an MCP server so the model can call search and fetch tools, or an API pipeline (search, condense to a token-capped pack, put it in the prompt).
Does running DeepSeek locally give it internet access?
No, it runs fully offline, which is why it can't answer anything after its training cutoff until you add a search step.
Transparency note: Grounder is a commercial product we build. The benchmark above tested DeepSeek-chat (the cloud model), not a self-hosted build; we're honest about that, and the frozen-at-cutoff logic and the search-and-fetch pipeline apply to whichever DeepSeek you run. The DIY path is valid, and the full pipeline is in the how-to guide.
