Dual Model Configuration
Claude Code uses a dual-threaded model architecture by default:
-
Main Thread Model: Configured via
ANTHROPIC_MODEL environment variable
- Used for primary code generation, conversations, and complex task processing
-
Secondary Thread Model: Configured via
ANTHROPIC_DEFAULT_HAIKU_MODEL environment variable
- Purpose: Lightweight / fast-task model
- Use cases:
- Background tasks (file monitoring, linter checks, etc.)
- Quick responses (simple questions, completion suggestions)
- Low-priority auxiliary tasks
Basic Configuration (Dual Model, Recommended)
Mac / Linux
Windows CMD
Windows PowerShell
export ANTHROPIC_BASE_URL="https://llm.ai-nebula.com"
export ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
export ANTHROPIC_MODEL="kimi-k2-250905"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="claude-haiku-4-5-20251001"
cd your-project-folder
claude
set ANTHROPIC_BASE_URL=https://llm.ai-nebula.com
set ANTHROPIC_AUTH_TOKEN=sk-zbTYx*******************************fceTvn5
set ANTHROPIC_MODEL=kimi-k2-250905
set ANTHROPIC_DEFAULT_HAIKU_MODEL=claude-haiku-4-5-20251001
cd your-project-folder
claude
$env:ANTHROPIC_BASE_URL="https://llm.ai-nebula.com"
$env:ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
$env:ANTHROPIC_MODEL="kimi-k2-250905"

Single Model Configuration (Optional)
If you only need to use a single model, there are two configuration methods:
Method 1: Configure both environment variables to the same model
Set both ANTHROPIC_MODEL and ANTHROPIC_DEFAULT_HAIKU_MODEL to the same model (for example, both use kimi-k2-250905):
Mac / Linux
Windows CMD
Windows PowerShell
export ANTHROPIC_BASE_URL="https://llm.ai-nebula.com"
export ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
export ANTHROPIC_MODEL="kimi-k2-250905"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="kimi-k2-250905"
cd your-project-folder
claude
set ANTHROPIC_BASE_URL=https://llm.ai-nebula.com
set ANTHROPIC_AUTH_TOKEN=sk-zbTYx*******************************fceTvn5
set ANTHROPIC_MODEL=kimi-k2-250905
set ANTHROPIC_DEFAULT_HAIKU_MODEL=kimi-k2-250905
cd your-project-folder
claude
$env:ANTHROPIC_BASE_URL="https://llm.ai-nebula.com"
$env:ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
$env:ANTHROPIC_MODEL="kimi-k2-250905"
$env:ANTHROPIC_DEFAULT_HAIKU_MODEL="kimi-k2-250905"
cd your-project-folder
claude
ANTHROPIC_DEFAULT_HAIKU_MODEL (i.e., claude-haiku-4-5-20251001).
