## Flowchart: Evolution of AI Models and Resource Types (2022-2025.03)
### Overview
The image depicts a vertical timeline (2022-2025.03) with branching pathways representing AI model development. Key elements include:
- A central vertical axis labeled with years (2022-2025.03)
- Colored boxes (yellow/gray) connected by arrows, representing AI models
- A legend at the bottom explaining color coding
- Decorative elements: a pink tree with cherry blossoms and a cartoon snake
### Components/Axes
1. **Timeline Axis** (Left side):
- Vertical axis labeled with years: 2022, 2023, 2024, 2025.01, 2025.02, 2025.03
- Dotted horizontal lines separate years
2. **Model Boxes**:
- Yellow boxes: Open Resource (per legend)
- Gray boxes: Close Resource (per legend)
- Examples: "DeepSeek-R1" (2022), "OpenAI-01" (2022), "Qwen2.5Math" (2025.01)
3. **Legend** (Bottom center):
- Yellow: Open Resource
- Gray: Close Resource
4. **Decorative Elements**:
- Pink tree with cherry blossoms (bottom center)
- Cartoon snake with red scarf (bottom right)
### Detailed Analysis
**Timeline Progression**:
- **2022**:
- Open Resource: DeepSeek-R1, CoT, MathPrompter
- Close Resource: OpenAI-01, Quiet-STaR
- **2023**:
- Open Resource: PlanningTokens, MuSR, Step-DPO
- Close Resource: ReST, SelfCheck
- **2024**:
- Open Resource: FastMCTS, Sky-T1, LIMOs
- Close Resource: ReVISE, AgentPRM
- **2025.01**:
- Open Resource: Qwen2.5Math, DART-Math
- Close Resource: ReST-MCTS*, AgentQ
- **2025.02**:
- Open Resource: Logic-RL, Full-Step-DPO
- Close Resource: RewardAgent, Aurora
- **2025.03**:
- Open Resource: ARiES, MM-Verify
- Close Resource: ThinkPO, SWE-RL
**Arrows and Relationships**:
- Arrows connect models across years, suggesting evolutionary pathways
- Some models branch into multiple successors (e.g., "ReST" → "ReST-MCTS*")
- Cross-year connections indicate iterative development
### Key Observations
1. **Resource Type Distribution**:
- 2022: 60% Open Resource (3/5 models)
- 2025.03: 50% Open Resource (2/4 models)
- Trend: Slight decline in Open Resource models over time
2. **Model Complexity**:
- Later years show longer model names (e.g., "ReST-MCTS*")
- 2025 models include specialized variants (e.g., "ReST-MCTS*")
3. **Decorative Symbolism**:
- Cherry blossoms may symbolize growth/innovation
- Snake with red scarf could represent "hidden" or "dangerous" aspects of AI
### Interpretation
The flowchart illustrates the evolution of AI models from 2022 to 2025, showing:
1. **Resource Shift**: While Open Resource models dominated early development, later years show increased parity with Close Resource models
2. **Specialization Trend**: Later models (2025) show more specialized variants (e.g., "ReST-MCTS*")
3. **Iterative Development**: Arrows suggest models build on predecessors, with some pathways converging (e.g., multiple models leading to "ReST-MCTS*")
4. **Symbolic Elements**: The cherry blossoms and snake may represent the dual nature of AI progress - beautiful innovation with potential risks
The data suggests a maturing AI ecosystem where resource types (Open vs. Close) become more balanced over time, with increasing specialization in later years. The decorative elements add narrative depth, hinting at both the aesthetic and perilous aspects of AI development.
