Model Switching

/model                          # Interactive picker (fetches live models from provider API when supported)
/model list                     # List all available models from the active provider API
/model claude-sonnet-4-7        # Switch by full ID
/model sonnet                   # Alias-based switching
--model opus                    # CLI flag at startup

For providers with a /v1/models endpoint (OpenAI, DeepSeek, NVIDIA, etc.), the picker fetches live models from the API instead of the static providers.json list. The picker shows all models from every provider in named sections — not just the active provider's models. Recent models appear at top with the active provider's default. Select any model from any provider directly.

Model switching is instant — the next conversation turn uses the new model. Previous context is preserved.

Model Aliases

Short aliases are resolved to full model IDs: sonnet, opus, haiku, gpt5, flash, etc.

CLI Flags for Models

FlagDescription
--model <name>Set model at startup (e.g., --model sonnet or --model claude-opus-4-7)
--effort <level>Set reasoning effort: low, medium, high, max
--max-turns <N>Limit agentic turns in non-interactive mode
--thinking <mode>Thinking mode: enabled, adaptive, disabled
--fallback-model <model>Fallback when primary model is overloaded (print mode only)
--task-budget <tokens>API-side task budget in tokens
--max-budget-usd <amount>Maximum spend on API calls (print mode only)

Model Capabilities

Each model declaration in providers.json includes:

  • Model ID and display label
  • Context window (maxContext) and max output tokens (maxOutput)
  • Tool calling type (native, none)
  • Vision support
  • Streaming mode (full, partial)
  • Reasoning support
  • System prompt support
  • Tags (for filtering): fast, verified, recommended, latest, free, vision, tools, native, moe, local
