Advanced Features

​
Dual LLM Configuration

Cipher supports separate evaluation LLMs for enhanced performance: 
# Main LLM for conversation
llm:
  provider: anthropic
  model: claude-3-5-haiku-20241022
  apiKey: $ANTHROPIC_API_KEY
  maxIterations: 50

# Evaluation LLM for reflection/analysis
evalLlm:
  provider: anthropic
  model: claude-3-7-sonnet-20250219
  apiKey: $ANTHROPIC_API_KEY

​
LM Studio (Local) Configuration

# Run LM Studio locally and load a chat model (e.g., mistral-7b-instruct)
llm:
  provider: lmstudio
  model: mistral-7b-instruct
  maxIterations: 50
  baseUrl: $LMSTUDIO_BASE_URL  # default: http://localhost:1234/v1
Notes:
  • No API key required (uses an OpenAI-compatible local server)
  • Set LMSTUDIO_BASE_URL if you changed the default port or host
  • Tool calling is supported via OpenAI-compatible schema
The purpose of evalLlm is for reflection memory evaluation. If you want to learn more, see the Reflection Memory documentation.

​
Provider-Specific Features

Tool Calling Support All providers support cipher’s advanced tool calling:
  • OpenAI: Native function calling with JSON schema
  • Anthropic: Tool use with structured inputs
  • OpenRouter: Provider-dependent tool support
  • Ollama: OpenAI-compatible tool calling
  • AWS Bedrock: Tool calling (provider-dependent, varies by model)
  • Azure OpenAI: OpenAI-compatible function/tool calling
  • Gemini: Function calling, structured output, code execution
  • Qwen: Hermes-style and OpenAI-compatible tool/function calling
Message Formatting Each provider has optimized message formatting:
  • Context Management: Intelligent conversation history
  • Image Support: Vision capabilities where available
  • Error Handling: Robust retry logic and error recovery

​
Configuration Validation

Cipher validates all LLM configurations at startup: Schema validation ensures:
  • provider: Must be ‘openai’, ‘anthropic’, ‘openrouter’, or ‘ollama’
  • model: Must be non-empty string
  • apiKey: Required for cloud providers (not Ollama)
  • maxIterations: Must be positive integer (default: 50)
  • baseURL: Must be valid URL if provided
Error Handling:
  • Startup Validation: Catch configuration errors early
  • Runtime Retry: Automatic retry with exponential backoff
  • Graceful Fallback: Continue operation when possible

​
Performance Optimization

maxIterations Configuration: 
# Conservative (faster responses)
maxIterations: 25

# Balanced (default)
maxIterations: 50

# Aggressive (complex tasks)
maxIterations: 100
Model Selection Tips:
  • Development: Use faster, cheaper models (gpt-4.1-mini, claude-3-haiku)
  • Production: Use more capable models (gpt-4.1, claude-4-sonnet)
  • Local Development: Use Ollama for cost-free iteration
