Provider Configuration

gcop-rs supports multiple LLM providers. You can use built-in providers or add custom ones.

Built-in Providers

Claude (Anthropic)

[llm.providers.claude]
api_key = "sk-ant-your-key"
model = "claude-sonnet-4-5-20250929"
temperature = 0.3
max_tokens = 2000

Get API Key: https://console.anthropic.com/

Available Models:

• claude-sonnet-4-5-20250929 (recommended)
• claude-opus-4-5-20251101 (most powerful)
• claude-3-5-sonnet-20241022 (older version)

OpenAI

[llm.providers.openai]
api_key = "sk-your-openai-key"
model = "gpt-4-turbo"
temperature = 0.3

Get API Key: https://platform.openai.com/

Available Models:

• gpt-4-turbo
• gpt-4
• gpt-3.5-turbo

Ollama (Local)

[llm.providers.ollama]
endpoint = "http://localhost:11434/api/generate"
model = "codellama:13b"

Setup:

# Install Ollama
curl https://ollama.ai/install.sh | sh

# Pull a model
ollama pull codellama:13b

# Start server
ollama serve

Available Models: Any model available in Ollama (codellama, llama2, mistral, etc.)

Custom Providers

You can add any OpenAI or Claude compatible API using the api_style parameter.

DeepSeek

[llm.providers.deepseek]
api_style = "openai"
api_key = "sk-your-deepseek-key"
endpoint = "https://api.deepseek.com/v1/chat/completions"
model = "deepseek-chat"
temperature = 0.3

Get API Key: https://platform.deepseek.com/

Qwen (通义千问)

[llm.providers.qwen]
api_style = "openai"
api_key = "sk-your-qwen-key"
endpoint = "https://dashscope.aliyuncs.com/compatible-mode/v1/chat/completions"
model = "qwen-max"

Claude Proxy/Mirror

[llm.providers.claude-proxy]
api_style = "claude"
api_key = "your-key"
endpoint = "https://your-claude-proxy.com/v1/messages"
model = "claude-sonnet-4-5-20250929"

Custom OpenAI Compatible Service

[llm.providers.my-llm]
api_style = "openai"
api_key = "your-key"
endpoint = "https://api.example.com/v1/chat/completions"
model = "custom-model"

API Style Parameter

The api_style parameter determines which API implementation to use:

Value	Description	Compatible Services
"openai"	OpenAI Chat Completions API	OpenAI, DeepSeek, Qwen, most custom services
"claude"	Anthropic Messages API	Claude, Claude proxies/mirrors
"ollama"	Ollama Generate API	Local Ollama only

If api_style is not specified, it defaults to the provider name (for backward compatibility with built-in providers).

Switching Providers

Using Command-Line

# Use different provider for one command
gcop-rs --provider openai commit
gcop-rs --provider deepseek review changes

Changing Default

Edit ~/.config/gcop/config.toml:

[llm]
default_provider = "deepseek"  # Change this

API Key Management

Config File vs Environment Variable

Priority: Config file > Environment variable

# This takes precedence
[llm.providers.claude]
api_key = "from-config"

# This is used if config file doesn't have api_key
export ANTHROPIC_API_KEY="from-env"

Standard Environment Variables

• Claude: ANTHROPIC_API_KEY
• OpenAI: OPENAI_API_KEY
• Ollama: No API key needed
