Fail to access DeepSeek-V3.2 through Claude Code
I try to use this amazing model in Claude Code. However, it seems that the base url as official website offers: https://api.deepseek.com/v3.2_speciale_expires_on_20251215 is wrong. I get error code: API Error: 404 status code (no body). This is my Claude Code configuration:
{
"env": {
"ANTHROPIC_BASE_URL": "https://api.deepseek.com/v3.2_speciale_expires_on_20251215",
"ANTHROPIC_AUTH_TOKEN": "${My key}",
"API_TIMEOUT_MS": "3000000",
"CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
"ANTHROPIC_MODEL": "deepseek-reasoner",
"ANTHROPIC_SMALL_FAST_MODEL": "deepseek-reasoner",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "deepseek-reasoner",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "deepseek-reasoner",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-reasoner"
},
"enabledPlugins": {
"document-skills@anthropic-agent-skills": true
}
}
How can I fix it. I can't wait to experience it in Claude Code.
v3.2_speciale is tuned just for reasoning, not agentic work
{
"env": {
"ANTHROPIC_AUTH_TOKEN": "sk-key",
"ANTHROPIC_BASE_URL": "https://api.deepseek.com/anthropic",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-reasoner",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "deepseek-reasoner",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "deepseek-reasoner",
"ANTHROPIC_MODEL": "deepseek-reasoner",
"CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1
}
} this will work.
The v3.2_speciale_expires_on_20251215 endpoint is an OpenAI-format endpoint, so it cannot be used by claude code.
You can use https://api.deepseek.com/anthropic for claude-compatible endpoint, but it can only access DeepSeek-V3.2 model, not DeepSeek-V3.2-Speciale.
