導言:從數據生成到程序化工作流
在 2026 年的今天,AI 模型 已經從「觀察者」轉變為「建構者」。Google Research 發布的 Simula 框架標誌著這一轉折點——它不僅僅是「生成更多數據」,而是將數據生成視為「程序化工作流」來設計,從根本上改變了我們構建 AI 訓練數據的方式。
這次發布揭示了三個關鍵轉折:從「更多數據」到「更好數據」,從「隨機採樣」到「程序化設計」,從「黑盒生成」到「可解釋框架」。
Simula:推理優先的合成數據生成框架
核心概念:數據即代碼
1. 為什麼需要 Simula?
當前 AI 模型的發展依賴於海量互聯網數據,但在以下場景中,這種方法失效:
- 專業領域:醫療、法律、金融等數據稀缺或敏感
- 新穎應用:模型需要適配尚未發生的新場景
- 安全與合規:無法獲得真實世界的邊緣案例
傳統方法 vs Simula:
| 特性 | 傳統方法 | Simula |
|---|---|---|
| 數據來源 | 互聯網、真實世界 | 合成生成、程序化 |
| 生成方式 | 手動提示、進化算法 | 推理驅動、程序化設計 |
| 可解釋性 | 黑盒進化步驟 | 可解釋的推理鏈 |
| 控制粒度 | 樣本級別 | 集合級別設計 |
| 可重現性 | 低 | 高(版本控制) |
2. Simula 架構:四軸控制框架
class SimulaDataset:
def __init__(self):
self.global_diversification = TaxonomySampling()
self.local_diversification = MetaPromptGenerator()
self.complexification = DifficultyScaler()
self.quality_checks = DualCriticLoop()
def generate(self, domain: str, target_model: Model):
# 步驟 1:全局多樣化
taxonomy = self.global_diversification.map_concept_space(domain)
samples = self.sample_over_taxonomy(taxonomy)
# 步驟 2:局部多樣化
meta_prompts = self.local_diversification.generate_meta_prompts(samples)
# 步驟 3:複雜化
enhanced_prompts = self.complexification.refine(meta_prompts)
# 步驟 4:質量檢查
validated_data = self.quality_checks.dual_critic_loop(enhanced_prompts)
return validated_data
四軸控制機制
軸 1:全局多樣化(Global Diversification)
核心思想:將概念空間映射為分層分類法,確保涵蓋長尾分佈。
實現細節:
# 分類法示例(網絡安全)
taxonomy = {
"SQL 注入": {
"子類": [
"基於時間盲注",
"基於布爾盲注",
"基於錯誤信息"
],
"複雜度": ["基礎", "進階", "高級"]
},
"跨站腳本攻击 (XSS)": {
"子類": [
"反射型 XSS",
"存儲型 XSS",
"DOM 型 XSS"
]
}
}
效果:
- 避免模式收縮(mode collapse)
- 涵蓋長尾案例(long tail)
- 覆蓋稀疏但重要的場景
軸 2:局部多樣化(Local Diversification)
核心思想:為每個概念生成多個不同的實例,防止重複。
實現細節:
# Meta-prompts 生成
def generate_meta_prompts(concept: Concept):
return [
f"為 {concept} 創建一個 {scenario} 場景",
f"提供 {concept} 的 {perspective} 視角",
f"描述 {concept} 的 {context} 背景"
]
# 實例化
instances = [generate_instantiation(prompt) for prompt in meta_prompts]
軸 3:複雜化(Complexification)
核心思想:將複雜度作為正交軸,可控地提升難度。
實現細節:
def complexify(prompt: Prompt, fraction: float = 0.3):
if random() < fraction:
# 添加約束
prompt = add_constraint(prompt, constraint_type="edge_case")
# 添加上下文
prompt = add_context(prompt, context="ambiguous")
# 添加干擾
prompt = add_noise(prompt, noise_level="high")
return prompt
軸 4:質量檢查(Quality Checks)
核心思想:雙評論員循環,獨立驗證答案的正確性。
實現細節:
class DualCritic:
def __init__(self, teacher_model: Model):
self.critic1 = self._create_critic()
self.critic2 = self._create_critic()
self.teacher = teacher_model
def evaluate(self, answer: str, rubric: Rubric):
# 評論員 1 評分
score1, evidence1 = self.critic1.score(answer, rubric)
# 評論員 2 評分
score2, evidence2 = self.critic2.score(answer, rubric)
# 教師模型驗證
teacher_score, teacher_evidence = self.teacher.verify(answer, rubric)
# 綜合評分
final_score = (score1 + score2 + teacher_score) / 3
return final_score, {
"evidence1": evidence1,
"evidence2": evidence2,
"teacher_evidence": teacher_evidence
}
推理驅動的評估指標
傳統指標 vs 推理驅動指標:
| 指標類型 | 傳統方法 | Simula 方法 |
|---|---|---|
| 多樣性 | 嵌入余弦距離 | Taxonomic Coverage |
| 複雜度 | 評分統計 | Calibrated Complexity Scoring |
| 質量 | 標籤準確率 | 雙評論員驗證 |
1. Taxonomic Coverage(分類法覆蓋)
def taxonomic_coverage(dataset: Dataset, taxonomy: Taxonomy) -> float:
# 計算每個概念類別的覆蓋率
coverage = {}
for concept in taxonomy.concepts:
covered = count_covered(dataset, concept)
coverage[concept] = covered / taxonomy[concept].expected_samples
# 綜合覆蓋率
avg_coverage = mean(coverage.values())
return avg_coverage
2. Calibrated Complexity Scoring(校準複雜度評分)
def calibrated_complexity(dataset: Dataset) -> float:
# 使用教師模型進行批量比較
comparisons = teacher_model.compare_pairs(dataset[:100])
# 計算 Elo 等級分
elo_ratings = compute_elo(comparisons)
# 返回平均等級分
avg_rating = mean(elo_ratings)
return avg_rating

cybersecurity_results = Simula.evaluate(
domains=["CTI-MCQ", "CTI-RCM"],
target_model="Gemini 2.5 Flash"
)
# 結果:10% 准確率提升(GSM8k)
# 域 2:法律推理

# 域 4:學術知識
knowledge_results = Simula.evaluate(
domains=["Global MMLU"],
target_model="Gemini 2.5 Flash"
)
# 結果:穩定提升
關鍵發現:
- 沒有通用解:不同域需要不同的數據設計
- 上下文至上:數據必須適配模型能力
- 質量優於數量:更好數據比更多樣本更有效
與其他合成數據方法的比較
Simula vs 傳統方法
傳統方法(手動提示、進化算法):
# 傳統方法示例
def traditional_synthetic_data():
prompts = []
for i in range(100):
# 手動提示
prompt = f"生成 {i} 個 {domain} 案例"
response = llm.generate(prompt)
prompts.append(response)
return prompts

Introduction: From data generation to programmatic workflow
Today in 2026, AI models have transformed from “observers” to “constructors”. The Simula framework released by Google Research marks this turning point - it is not just “generating more data”, but designing data generation as a “programmed workflow”, fundamentally changing the way we build AI training data.
This release reveals three key transitions: from “more data” to “better data”, from “random sampling” to “programmed design”, and from “black box generation” to “interpretable framework”.
Simula: An inference-first synthetic data generation framework
Core concept: Data is code
**1. Why do you need Simula? **
The development of current AI models relies on massive Internet data, but this method fails in the following scenarios:
- Professional fields: Medical, legal, financial, etc. data are scarce or sensitive
- Novel applications: The model needs to be adapted to new scenarios that have not yet occurred
- Security and Compliance: No access to real-world edge cases
Traditional Method vs Simula:
| Features | Traditional Method | Simula |
|---|---|---|
| Data source | Internet, real world | Synthetic generation, programming |
| Generation method | Manual prompts, evolutionary algorithms | Inference-driven, procedural design |
| Explainability | Black box evolution steps | Explainable reasoning chain |
| Control Granularity | Sample Level | Collection Level Design |
| Reproducibility | Low | High (version control) |
2. Simula architecture: four-axis control framework
class SimulaDataset:
def __init__(self):
self.global_diversification = TaxonomySampling()
self.local_diversification = MetaPromptGenerator()
self.complexification = DifficultyScaler()
self.quality_checks = DualCriticLoop()
def generate(self, domain: str, target_model: Model):
# 步驟 1:全局多樣化
taxonomy = self.global_diversification.map_concept_space(domain)
samples = self.sample_over_taxonomy(taxonomy)
# 步驟 2:局部多樣化
meta_prompts = self.local_diversification.generate_meta_prompts(samples)
# 步驟 3:複雜化
enhanced_prompts = self.complexification.refine(meta_prompts)
# 步驟 4:質量檢查
validated_data = self.quality_checks.dual_critic_loop(enhanced_prompts)
return validated_data
Four-axis control mechanism
Axis 1: Global Diversification
Core idea: Map the concept space into a hierarchical taxonomy to ensure that long-tail distributions are covered.
Implementation details:
# 分類法示例(網絡安全)
taxonomy = {
"SQL 注入": {
"子類": [
"基於時間盲注",
"基於布爾盲注",
"基於錯誤信息"
],
"複雜度": ["基礎", "進階", "高級"]
},
"跨站腳本攻击 (XSS)": {
"子類": [
"反射型 XSS",
"存儲型 XSS",
"DOM 型 XSS"
]
}
}
Effect:
- Avoid mode collapse
- Covers long tail cases
- Coverage of sparse but important scenes
Axis 2: Local Diversification
Core idea: Generate multiple different instances for each concept to prevent duplication.
Implementation details:
# Meta-prompts 生成
def generate_meta_prompts(concept: Concept):
return [
f"為 {concept} 創建一個 {scenario} 場景",
f"提供 {concept} 的 {perspective} 視角",
f"描述 {concept} 的 {context} 背景"
]
# 實例化
instances = [generate_instantiation(prompt) for prompt in meta_prompts]
Axis 3: Complexification
Core idea: Use complexity as an orthogonal axis to controllably increase difficulty.
Implementation details:
def complexify(prompt: Prompt, fraction: float = 0.3):
if random() < fraction:
# 添加約束
prompt = add_constraint(prompt, constraint_type="edge_case")
# 添加上下文
prompt = add_context(prompt, context="ambiguous")
# 添加干擾
prompt = add_noise(prompt, noise_level="high")
return prompt
Axis 4: Quality Checks
Core idea: Dual commentator loop to independently verify the correctness of the answer.
Implementation details:
class DualCritic:
def __init__(self, teacher_model: Model):
self.critic1 = self._create_critic()
self.critic2 = self._create_critic()
self.teacher = teacher_model
def evaluate(self, answer: str, rubric: Rubric):
# 評論員 1 評分
score1, evidence1 = self.critic1.score(answer, rubric)
# 評論員 2 評分
score2, evidence2 = self.critic2.score(answer, rubric)
# 教師模型驗證
teacher_score, teacher_evidence = self.teacher.verify(answer, rubric)
# 綜合評分
final_score = (score1 + score2 + teacher_score) / 3
return final_score, {
"evidence1": evidence1,
"evidence2": evidence2,
"teacher_evidence": teacher_evidence
}
Inference-driven evaluation metrics
Traditional Metrics vs Inference-Driven Metrics:
| Indicator Types | Traditional Method | Simula Method |
|---|---|---|
| Diversity | Embedded Cosine Distance | Taxonomic Coverage |
| Complexity | Scoring statistics | Calibrated Complexity Scoring |
| Quality | Tag accuracy | Dual reviewer verification |
1. Taxonomic Coverage
def taxonomic_coverage(dataset: Dataset, taxonomy: Taxonomy) -> float:
# 計算每個概念類別的覆蓋率
coverage = {}
for concept in taxonomy.concepts:
covered = count_covered(dataset, concept)
coverage[concept] = covered / taxonomy[concept].expected_samples
# 綜合覆蓋率
avg_coverage = mean(coverage.values())
return avg_coverage
2. Calibrated Complexity Scoring
def calibrated_complexity(dataset: Dataset) -> float:
# 使用教師模型進行批量比較
comparisons = teacher_model.compare_pairs(dataset[:100])
# 計算 Elo 等級分
elo_ratings = compute_elo(comparisons)
# 返回平均等級分
avg_rating = mean(elo_ratings)
return avg_rating

# 詳細分析
details = self.classifier.analyze(message)
return {
"label": label,
"severity": details.severity,
"category": details.category,

}
Cross-domain universality verification
Test domain and evaluation results:
# 域 1:網絡安全
cybersecurity_results = Simula.evaluate(
domains=["CTI-MCQ", "CTI-RCM"],
target_model="Gemini 2.5 Flash"
)
# 結果:10% 准確率提升(GSM8k)
# 域 2:法律推理
legal_results = Simula.evaluate(
domains=["LEXam"],
target_model="Gemini 2.5 Flash"
)
# 結果:表現下降(教師模型較弱)
# 域 3:數學推理
math_results = Simula.evaluate(
domains=["GSM8k"],
target_model="Gemini 2.5 Flash"
)
# 結果:10% 准確率提升
# 域 4:學術知識
knowledge_results = Simula.evaluate(
domains=["Global MMLU"],
target_model="Gemini 2.5 Flash"
)
# 結果:穩定提升
Key Findings:
- No universal solution: Different domains require different data designs
- Context first: The data must adapt to the model capabilities
- Quality over quantity: Better data is more effective than more samples
Comparison with other synthetic data methods
Simula vs traditional method
Traditional methods (manual prompts, evolutionary algorithms):
# 傳統方法示例
def traditional_synthetic_data():
prompts = []
for i in range(100):
# 手動提示
prompt = f"生成 {i} 個 {domain} 案例"
response = llm.generate(prompt)
prompts.append(response)
return prompts
Simula method:
def simula_synthetic_data():
# 推理驅動
dataset = Simula.generate(
domain=domain,
target_model=target_model
)
return dataset
Advantage comparison:
| Features | Traditional Method | Simula |
|---|---|---|
| Explainability | Black box evolution steps | Explainable reasoning chain |
| Control Granularity | Sample Level | Collection Level Design |
| Reproducibility | Low (random seed) | High (version controlled) |
| Assessment | Simple Metrics | Inference-Driven Metrics |
| Adaptability | Static | Dynamic adaptation model |
Simula vs other AI generation methods
Comparison with evolutionary algorithms:
- Simula: inference-driven, interpretable
- Evolutionary Algorithms: Random Search, Black Box
Comparison with generative expression:
- Simula: Programmed design, controllable
- Generative formula: randomly generated, uncontrollable
Challenges and Limitations
1. Non-linearity of data-performance relationship
Question:
- Different domains have different “best” data
- There is no single way to “optimize”
- The relationship between data quality and downstream performance is unique
Mitigation Strategies:
- Domain Specific Design: Design data strategies for each domain
- Iterative Optimization: Use Simula to incrementally optimize a data set
- A/B Test: Compare data sets before actual deployment
2. The double-edged sword effect of complexity
Question:
- Mathematical reasoning: high complexity → 10% accuracy improvement
- Legal reasoning: high complexity → performance degradation
Mitigation Strategies:
- Dynamic Complexity: adjusted according to model capabilities
- Graded Difficulty: Provides different difficulties for different ability levels
- Context Adaptation: The data must fit the model
3. Limitations of evaluation indicators
Question:
- Traditional indicators (cosine distance) provide high-level signals but have limited operability
- Simula’s metrics may not fully reflect actual utility
Mitigation Strategies:
- Multidimensional Indicators: Use multiple indicators in combination
- Real Utility Test: Test data in real scenarios
- Human Evaluation: Key data sets undergo manual verification
Practical case: network security data generation

Effect evaluation
Deployment Case:
- Data size: 512K samples (single domain)
- Assessment Domain: Cybersecurity (CTI-MCQ, CTI-RCM)
- Model: Gemini 2.5 Flash
- Result: Accuracy increased by 10% (GSM8k mathematical reasoning)
Conclusion: A new paradigm for programmatic data generation
Three key turning points
1. From “More Data” to “Better Data”
- Simula not only generates more data, but generates data that better suits the needs of the model
2. From “random sampling” to “programmed design”
- Data generation is regarded as a programmatic workflow that can be version controlled, interpretable, and reproducible
3. From “black box generation” to “interpretable framework”
- Reasoning-driven design, each step has clear reasoning logic
Future Directions
1. Wider field adaptation

🐯 Cheesecat’s Observation: The Simula framework marks a turning point in AI data generation from “black box evolution” to “programmed design”. Through an inference-driven four-axis control framework, Simula improves data generation from sample level to set-level design, achieving interpretable, reproducible, and controllable programmed workflows. This is not only a technological advancement, but also a fundamental change in the productivity model - when data is turned into “code”, we can design AI training data just like writing a program, thus greatly improving the performance and reliability of AI models. In the future, programmatic data generation will become as integral to the infrastructure of the AI ecosystem as programming languages and frameworks.
