- **Expensive models**: high token cost, low failure rate
- **Optimal**: minimizes `E[total_cost] = Σ P(retry_n) × cost_n`
Default ladder: `claude-haiku-4.5` → `claude-sonnet-4` → `claude-sonnet-4.5`
Default ladder: `gemini-3-flash` → `qwen/qwen3-235b-a22b-instruct` → `deepseek/deepseek-v3.2`
### Model Preferences
**NEVER use Claude models** (anthropic/claude-*) - they are prohibitively expensive.
**Preferred models (in order):**
1. `google/gemini-3-flash-preview` - Fast, cheap, good tool use
2. `qwen/qwen3-235b-a22b-instruct` - Strong reasoning, affordable
3. `deepseek/deepseek-v3.2` - Good value, capable
4. `x-ai/grok-4.1-fast` - Fast alternative
5. `mistralai/mistral-large-2512` - European provider option
When implementing model selection or defaults, always prefer these models over Claude.
## Model Family System
The agent automatically upgrades outdated model names to the latest versions. This prevents issues where training data suggests old model names like `claude-3.5-sonnet` instead of the newer, cheaper, and smarter `claude-sonnet-4.5`.
The agent automatically upgrades outdated model names to the latest versions. This prevents issues where training data suggests old model names like `gemini-1.5-flash` instead of the newer `gemini-3-flash-preview`.
### How It Works
1. **Model Families**: Models are grouped into families (e.g., `claude-sonnet`, `gpt-4`)

2. **Auto-Upgrade**: When an old model is requested, it's resolved to the latest in its family
3. **Aliases**: Common aliases like "sonnet" or "gpt4" resolve to the latest
