## Bar Chart: Task Success Rate (%) by Model and Tool
### Overview
The chart compares task success rates (%) across four AI models (Opus 4.5, Sonnet 4.5, GLM 4.6, GPT 5.1) and four tools (Cursor, Codex, Claude Code, OpenCode). Each model has grouped bars representing tool performance, with success rates ranging from 0% to 16%.
### Components/Axes
- **X-axis**: Models (Opus 4.5, Sonnet 4.5, GLM 4.6, GPT 5.1)
- **Y-axis**: Task Success Rate (%) (0–16)
- **Legend**:
- Red = Cursor
- Blue = Codex
- Green = Claude Code
- Yellow = OpenCode
- **Legend Position**: Top-right corner
- **Bar Order**: For each model, bars are ordered as Cursor → Claude Code → Codex → OpenCode (note: this differs from the legend's left-to-right order).
### Detailed Analysis
1. **Opus 4.5**:
- Cursor (red): 12%
- Claude Code (green): 8%
- Codex (blue): 4%
- OpenCode (yellow): 2%
2. **Sonnet 4.5**:
- Cursor (red): 12%
- Claude Code (green): 10%
- Codex (blue): 10%
- OpenCode (yellow): 4%
3. **GLM 4.6**:
- Codex (blue): 12%
- Claude Code (green): 10%
- OpenCode (yellow): 8%
- Cursor (red): N/A
4. **GPT 5.1**:
- Cursor (red): 2%
- OpenCode (yellow): 6%
- Claude Code (green): N/A
- Codex (blue): N/A
### Key Observations
- **Cursor Dominance**: Achieves highest success rates (12%) in Opus 4.5 and Sonnet 4.5.
- **Codex Peak**: Outperforms all tools in GLM 4.6 (12%).
- **Claude Code Consistency**: Maintains 8–10% success rates across Opus 4.5 and Sonnet 4.5.
- **OpenCode Growth**: Shows increasing success rates (4% → 6% → 8%) across models.
- **GPT 5.1 Anomaly**: Cursor success rate drops to 2%, while OpenCode rises to 6%.
### Interpretation
The data suggests tool effectiveness varies significantly by model:
- **Cursor** excels in Opus and Sonnet 4.5, possibly indicating optimization for these models' architectures.
- **Codex** dominates GLM 4.6, suggesting specialized compatibility.
- **OpenCode** improves performance in later models (GLM 4.6, GPT 5.1), hinting at adaptability to newer architectures.
- **N/A Values** in GLM 4.6 (Cursor) and GPT 5.1 (Codex/Claude Code) imply tool-model incompatibility or unavailability.
The chart highlights the importance of tool-model pairing for task success, with no single tool universally dominant. OpenCode's rising trend may indicate emerging utility in advanced models.
