How to use DeepSeek's List Models API without guessing which model IDs are live
DeepSeek's official API reference includes a `GET /models` endpoint for checking the currently available model identifiers programmatically. That matters for teams still cleaning up old alias usage, validating staging configs, or deciding whether to trust a hardcoded model string. The endpoint is simple, but the operational question is not: use `/models` to confirm what the API exposes right now, then use the pricing page to decide which of those models should carry your workload.
1. What the official `GET /models` endpoint actually returns
DeepSeek's reference says `GET /models` lists the currently available models and basic information such as owner and availability. The example response currently shows `deepseek-v4-flash` and `deepseek-v4-pro`, each with `object: "model"` and `owned_by: "deepseek"`.
That makes the endpoint useful as a runtime discovery surface. It tells your application which top-level model IDs the API is willing to expose, but it does not replace the pricing page or longer guides for feature behavior.
| Field | Meaning | Why it matters |
|---|---|---|
| object | `list` | Confirms the response is a collection payload. |
| data[].id | Model identifier | Use this exact value in API requests. |
| data[].object | `model` | Confirms each array item is a model record. |
| data[].owned_by | Owning organization | Useful for validation and debugging. |

2. `/models` is not the same thing as the pricing page
The same official reference tells readers to check Models & Pricing for currently supported models. That wording matters. `/models` is a programmatic discovery endpoint; the pricing page is the product contract page for rates, context window, max output, and public support framing.
If your deployment pipeline wants a fast preflight check, `/models` is the right place. If finance or operations needs to understand cost, concurrency, or whether Flash versus Pro is the right lane, the pricing page is the stronger source.
A clean DeepSeek workflow usually uses both: fetch `/models` to validate identifiers, then map traffic intentionally between `deepseek-v4-flash` and `deepseek-v4-pro` based on cost and quality requirements.
Sources checked
- DeepSeek official Models & Pricing page - Use this for rates, context, and concurrency rather than `/models` alone.
- DeepSeek official Lists Models reference - The reference page explicitly points readers back to Models & Pricing.
3. When to call List Models in production or staging
Call `GET /models` when you need to prove that a configured model name is real before a job starts. This is especially useful for internal dashboards, deploy checks, CLI wrappers, and agent systems that load provider config dynamically.
It is also a safer verification step during the alias-cleanup window. If a team still has old snippets floating around, `/models` helps reinforce that the official public V4 names are the identifiers to build around today.
Do not poll the endpoint on every request just to choose between Flash and Pro. That is routing logic, not discovery. Cache the result, alert on unexpected changes, and keep model selection in your application config.
const response = await fetch("https://api.deepseek.com/models", {
headers: { Authorization: `Bearer ${process.env.DEEPSEEK_API_KEY}` },
});
if (!response.ok) {
throw new Error("DeepSeek model discovery failed");
}
const payload = await response.json();
const modelIds = payload.data.map((item: { id: string }) => item.id);
if (!modelIds.includes("deepseek-v4-flash")) {
throw new Error("Expected DeepSeek V4 Flash to be available");
}4. The practical migration angle for DeepSeek buyers and builders
Many support questions around DeepSeek are really configuration hygiene problems. Teams copy a community snippet, assume a model string still exists, and only discover the mistake after deployment. Using `/models` as a preflight check is a cleaner habit.
For cost-sensitive routes, combine this with `/guides/deepseek-v4-pro-vs-flash` and `/guides/deepseek-v4-pricing-per-million-tokens`. Those pages help you decide what to do after validation, rather than only confirming that an ID exists.
If you need in-stock official DeepSeek access for the site workflows this repo supports, `/pricing` remains the buyer path. The `/models` endpoint does not imply any new local resale inventory by itself.
FAQ
What does DeepSeek `GET /models` return right now?
The official example currently shows `deepseek-v4-flash` and `deepseek-v4-pro`, each owned by `deepseek`.
Should I use `/models` instead of the pricing page?
Use `/models` for runtime discovery and validation. Use the pricing page for rates, context limits, and public support details.
Should my app call `/models` on every request?
Usually no. Cache the result for validation or deploy checks, then keep actual model routing in your application config.
Does the List Models endpoint prove a model is sold on this site's `/pricing` page?
No. API availability and this repo's stocked Coding Plan inventory are separate. `/pricing` only lists inventory that is actually in stock.
DeepSeek's List Models endpoint is best treated as a runtime truth-check: use it to validate live model IDs, keep the pricing page as the cost contract, and avoid turning legacy or copied model names into production assumptions.
