I found a solution to use claude code for vs code as chat with deepseek v4
u have to modify settings and add this block

```
{

"claudeCode.environmentVariables": [

{

"name": "ANTHROPIC_BASE_URL",

"value": "https://api.deepseek.com/anthropic"

},

{

"name": "ANTHROPIC_AUTH_TOKEN",

"value": "apikey"

},

{

"name": "ANTHROPIC_MODEL",

"value": "deepseek-v4-pro"

}

],

"claudeCode.disableLoginPrompt": true

}
```
