DeepSeek OpenCode setup: use the official `/connect` flow before inventing custom endpoint hacks
DeepSeek's official OpenCode integration page is useful because it gives a simple provider-switch contract instead of a fragile pile of custom config guesses. The current guidance is to keep OpenCode updated, start the tool normally, open the provider connection flow with `/connect`, enter a DeepSeek API key, and then choose DeepSeek V4 Pro. That makes this a strong long-tail page for developers searching how to wire OpenCode to DeepSeek without losing time to outdated compatibility advice.
1. What DeepSeek officially supports in OpenCode
DeepSeek describes OpenCode as an open-source AI coding assistant available in terminal, web, and other forms. The important part for setup is not the branding. It is that DeepSeek now documents OpenCode as an official agent-integration path instead of leaving teams to rely on community snippets.
The same DeepSeek docs homepage now frames OpenCode alongside other supported agent tools, which is a stronger signal than a random social post or issue comment.

2. Upgrade first: the docs recommend OpenCode v1.14.24 or later
DeepSeek's page is unusually specific about compatibility: it strongly recommends OpenCode version `>= v1.14.24`. That is the first thing to check before debugging provider behavior.
If the DeepSeek option is missing or the provider flow behaves differently from the docs, validate the OpenCode version before rewriting prompts or searching for custom JSON overrides.
| Check | Official guidance | Why it matters |
|---|---|---|
| OpenCode version | Use v1.14.24 or later | Older builds may not match the documented DeepSeek connection flow |
| Credential source | Use a DeepSeek API key from DeepSeek Platform | The route is BYOK and still depends on your own DeepSeek account |
| Model choice | Select DeepSeek V4 Pro first | This is the default model named in the official setup page |

3. The shortest official path is `/connect`, not manual endpoint surgery
DeepSeek's migration path for existing OpenCode users is direct: start `opencode`, type `/connect`, search for `deepseek`, select the provider, enter your DeepSeek API key, and then choose DeepSeek V4 Pro.
That matters because this route keeps the setup inside the product's own connection flow. You do not need to start by inventing environment variables or editing files just to reach a working baseline.
1. Run: opencode
2. Type: /connect
3. Search for: deepseek
4. Select the DeepSeek provider
5. Paste your DeepSeek API key
6. Choose: DeepSeek-V4-Pro4. Start with V4 Pro, then benchmark Flash only after the baseline works
DeepSeek's OpenCode guide tells users to pick DeepSeek V4 Pro. That should be treated as the official baseline rather than an immutable rule.
Once the connection is stable, cost-sensitive teams can test whether DeepSeek V4 Flash is good enough for repetitive edits, lint-fix loops, or wide codebase exploration. The main discipline is to change one thing at a time: keep the same provider flow and credential, then switch only the model.
If your next question is how Pro and Flash differ operationally, continue with `/guides/deepseek-v4-pro-vs-flash`.
5. Common failure pattern: debugging the wrong layer
Most OpenCode-to-DeepSeek setup problems are ordinary compatibility or connection-flow issues, not model-quality issues. If the DeepSeek provider is not visible, first confirm the OpenCode version and repeat the `/connect` flow exactly.
If the provider exists but the session still fails, recheck that the key came from DeepSeek Platform and that you actually finished the provider-selection flow instead of assuming an older OpenAI-compatible path still matches the current UI.
6. Where this guide fits on a DeepSeek-first site
This page is support content, not a new plan listing. It does not mean OpenCode is sold on `/pricing`, and it does not change the site's inventory-gated product rules.
The correct conversion path stays narrow: learn the official OpenCode setup flow here, then visit `/pricing` only if you need an in-stock DeepSeek API key route.
If you want another terminal-first DeepSeek workflow, compare this page with `/guides/deepseek-deep-code-cli`, `/guides/deepseek-crush-agent-setup`, and `/guides/reasonix-deepseek-coding-agent`.
FAQ
How do I connect OpenCode to DeepSeek?
DeepSeek's official guide says to run `opencode`, type `/connect`, search for `deepseek`, select the provider, enter your API key, and then choose DeepSeek V4 Pro.
Which OpenCode version should I use with DeepSeek?
DeepSeek recommends OpenCode v1.14.24 or later to avoid compatibility issues.
Do I need to edit a config file for the basic OpenCode setup?
Not for the official baseline. DeepSeek documents the provider switch through OpenCode's `/connect` flow.
Should I start with DeepSeek V4 Pro or Flash in OpenCode?
Start with V4 Pro because that is the model selected in the official DeepSeek guide, then benchmark Flash later if you want cheaper repeated coding loops.
Does this page mean OpenCode is a purchasable plan on this site?
No. This is a guide page for DeepSeek integration. Purchasable products still appear only when actual stock exists on `/pricing`.
The OpenCode setup story is now refreshingly simple: keep the tool on a compatible version, use the built-in `/connect` flow, paste a DeepSeek key, and start with V4 Pro. That is a better baseline than treating every OpenAI-compatible coding assistant as if it needs a custom DeepSeek workaround.
