title: Models
|
||||
description: Configuring an LLM provider and model.
|
||||
---
|
||||
|
||||
OpenCode uses the [AI SDK](https://ai-sdk.dev/) and [Models.dev](https://models.dev) to support **75+ LLM providers** and it supports running local models.
|
||||
|
||||
---
|
||||
|
||||
## Providers
|
||||
|
||||
Most popular providers are preloaded by default. If you've added the credentials for a provider through the `/connect` command, they'll be available when you start OpenCode.
|
||||
|
||||
Learn more about [providers](/docs/providers).
|
||||
|
||||
---
|
||||
|
||||
## Select a model
|
||||
|
||||
Once you've configured your provider you can select the model you want by typing in:
|
||||
|
||||
```bash frame="none"
|
||||
/models
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Recommended models
|
||||
|
||||
There are a lot of models out there, with new models coming out every week.
|
||||
|
||||
:::tip
|
||||
Consider using one of the models we recommend.
|
||||
:::
|
||||
|
||||
However, there are only a few of them that are good at both generating code and tool calling.
|
||||
|
||||
Here are several models that work well with OpenCode, in no particular order. (This is not an exhaustive list nor is it necessarily up to date):
|
||||
|
||||
- GPT 5.2
|
||||
- GPT 5.1 Codex
|
||||
- Claude Opus 4.5
|
||||
- Claude Sonnet 4.5
|
||||
- Minimax M2.1
|
||||
- Gemini 3 Pro
|
||||
|
||||
---
|
||||
|
||||
## Set a default
|
||||
|
||||
To set one of these as the default model, you can set the `model` key in your
|
||||
OpenCode config.
|
||||
|
||||
```json title="opencode.json" {3}
|
||||
{
|
||||
"$schema": "https://opencode.ai/config.json",
|
||||
"model": "lmstudio/google/gemma-3n-e4b"
|
||||
}
|
||||
```
|
||||
|
||||
Here the full ID is `provider_id/model_id`. For example, if you're using [OpenCode Zen](/docs/zen), you would use `opencode/gpt-5.1-codex` for GPT 5.1 Codex.
|
||||
|
||||
If you've configured a [custom provider](/docs/providers#custom), the `provider_id` is key from the `provider` part of your config, and the `model_id` is the key from `provider.models`.
|
||||
|
||||
---
|
||||
|
||||
## Configure models
|
||||
|
||||
You can globally configure a model's options through the config.
|
||||
|
||||
```jsonc title="opencode.jsonc" {7-12,19-24}
|
||||
{
|
||||
"$schema": "https://opencode.ai/config.json",
|
||||
"provider": {
|
||||
"openai": {
|
||||
"models": {
|
||||
"gpt-5": {
|
||||
"options": {
|
||||
"reasoningEffort": "high",
|
||||
"textVerbosity": "low",
|
||||
"reasoningSummary": "auto",
|
||||
"include": ["reasoning.encrypted_content"],
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
"anthropic": {
|
||||
"models": {
|
||||
"claude-sonnet-4-5-20250929": {
|
||||
"options": {
|
||||
"thinking": {
|
||||
"type": "enabled",
|
||||
"budgetTokens": 16000,
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
Here we're configuring global settings for two built-in models: `gpt-5` when accessed via the `openai` provider, and `claude-sonnet-4-20250514` when accessed via the `anthropic` provider.
|
||||
The built-in provider and model names can be found on [Models.dev](https://models.dev).
|
||||
|
||||
You can also configure these options for any agents that you are using. The agent config overrides any global options here. [Learn more](/docs/agents/#additional).
|
||||
|
||||
You can also define custom variants that extend built-in ones. Variants let you configure different settings for the same model without creating duplicate entries:
|
||||
|
||||
```jsonc title="opencode.jsonc" {6-21}
|
||||
{
|
||||
"$schema": "https://opencode.ai/config.json",
|
||||
"provider": {
|
||||
"opencode": {
|
||||
"models": {
|
||||
"gpt-5": {
|
||||
"variants": {
|
||||
"high": {
|
||||
"reasoningEffort": "high",
|
||||
"textVerbosity": "low",
|
||||
"reasoningSummary": "auto",
|
||||
},
|
||||
"low": {
|
||||
"reasoningEffort": "low",
|
||||
"textVerbosity": "low",
|
||||
"reasoningSummary": "auto",
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Variants
|
||||
|
||||
Many models support multiple variants with different configurations. OpenCode ships with built-in default variants for popular providers.
|
||||
|
||||
### Built-in variants
|
||||
|
||||
OpenCode ships with default variants for many providers:
|
||||
|
||||
**Anthropic**:
|
||||
|
||||
- `high` - High thinking budget (default)
|
||||
- `max` - Maximum thinking budget
|
||||
|
||||
**OpenAI**:
|
||||
|
||||
Varies by model but roughly:
|
||||
|
||||
- `none` - No reasoning
|
||||
- `minimal` - Minimal reasoning effort
|
||||
- `low` - Low reasoning effort
|
||||
- `medium` - Medium reasoning effort
|
||||
- `high` - High reasoning effort
|
||||
- `xhigh` - Extra high reasoning effort
|
||||
|
||||
**Google**:
|
||||
|
||||
- `low` - Lower effort/token budget
|
||||
- `high` - Higher effort/token budget
|
||||
|
||||
:::tip
|
||||
This list is not comprehensive. Many other providers have built-in defaults too.
|
||||
:::
|
||||
|
||||
### Custom variants
|
||||
|
||||
You can override existing variants or add your own:
|
||||
|
||||
```jsonc title="opencode.jsonc" {7-18}
|
||||
{
|
||||
"$schema": "https://opencode.ai/config.json",
|
||||
"provider": {
|
||||
"openai": {
|
||||
"models": {
|
||||
"gpt-5": {
|
||||
"variants": {
|
||||
"thinking": {
|
||||
"reasoningEffort": "high",
|
||||
"textVerbosity": "low",
|
||||
},
|
||||
"fast": {
|
||||
"disabled": true,
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
### Cycle variants
|
||||
|
||||
Use the keybind `variant_cycle` to quickly switch between variants. [Learn more](/docs/keybinds).
|
||||

|
||||
|
||||
## Loading models
|
||||
|
||||
When OpenCode starts up, it checks for models in the following priority order:
|
||||
|
||||
1. The `--model` or `-m` command line flag. The format is the same as in the config file: `provider_id/model_id`.
|
||||
|
||||
2. The model list in the OpenCode config.
|
||||
|
||||
```json title="opencode.json"
|
||||
{
|
||||
"$schema": "https://opencode.ai/config.json",
|
||||
"model": "anthropic/claude-sonnet-4-20250514"
|
||||
}
|
||||
```
|
||||
|
||||
The format here is `provider/model`.
|
||||
|
||||
3. The last used model.
|
||||
|
||||
4. The first model using an internal priority.
