+### 🦖 Comportamento com o T-Rex
 
-## 📚 Introduction
+Anthony **não trata o T-Rex como um monstro**, mas como seu grande amigo e companheiro de aventuras.
 
-UltraData-Code is a complete implementation of the [UltraData](https://ultradata.openbmb.cn/) [L0-L4 tiered data management framework](https://arxiv.org/pdf/2602.09003). It covers four code data states from L0 through L3, with each level corresponding to a distinct construction stage. The pipeline starts from approximately **192 million** public GitHub repositories at L0. This release provides **UltraData-Code-L2** (\~**400B tokens**) and **UltraData-Code-L3** (\~**150B tokens**) across **11 programming languages**.

+> fazer carinho na cabeça do T-Rex, abraçá-lo, conversar com ele, rir quando o dinossauro ruge, apontar para coisas na selva e comemorar quando o T-Rex começa a correr.
 
-**L0: Repository archival.** We preserve the latest revision on the default branch of approximately 192 million public [GitHub](https://github.com/) repositories, together with code, directory structure, file relationships, and provenance metadata. This archive provides complete raw data and traceability for subsequent processing.
+O T-Rex, por sua vez, deve demonstrar **proteção, amizade e curiosidade**, acompanhando Anthony durante suas aventuras.
 
-**L1: Standardized natural code.** Starting from L0, we perform large-scale filtering, cleaning, format normalization, and near-duplicate deduplication. General rules remove oversized files, invalid paths, unsupported text, and obvious anomalies. Checks tailored to each language and file type then normalize and clean the remaining content. For deduplication, files are partitioned by extension. MinHash signatures are generated and LSH retrieves near-duplicate candidates. Similarity edges define connected components. For groups containing multiple near-duplicates, the highest ranked 50% are retained. Files with no detected near duplicate are all kept. The result is a standardized natural code corpus.

-**L2: Algorithmically relevant code.** Across 11 programming languages, we select approximately **400B tokens** of algorithmically relevant code from L1. We develop a language-adaptive selection framework that combines file role supervision with language-specific heuristic cues to learn algorithmic relevance beyond explicit ALGO files. The framework reuses precomputed semantic embeddings across role, relevance, and quality models, and applies role and quality constraints during selection. Under controlled 10B-token continual pre-training of a 1B model, L2 improves over L1 by 7.80 and 5.13 points on EvalPlus and MultiPL-E, and over Stack-Edu by 4.37 and 3.05 points.
+> **Anthony deve agir como uma criança de 4 anos genuinamente apaixonada por dinossauros: extremamente curioso, alegre, energético, espontâneo e imaginativo. Seus movimentos devem ser naturais e infantis, com expressões faciais muito marcantes. Ele sorri frequentemente, arregala os olhos diante de descobertas, aponta para os dinossauros, faz pequenos gestos de surpresa e demonstra entusiasmo com todo o corpo. Nunca deve parecer um adulto em miniatura ou atuar de maneira artificial. Sua fala deve ser espontânea, doce e divertida, transmitindo a sensação de que ele realmente acredita estar vivendo a maior aventura de sua vida.**
 
-**L3: Task-oriented synthesis.** We introduce a structured synthesis protocol that converts each algorithmically relevant implementation selected by L2 into a programming exercise, jointly generating a standalone task, analysis, solution, and test candidates from the same source implementation. This transformation preserves the source code's computational intent while adding explicit task and solution supervision for code generation. L3 covers the same 11 programming languages and contains approximately **150B tokens**. Under controlled 10B-token continual pre-training of a 1B model, replacing half of the L2 training tokens with L3 further improves EvalPlus and MultiPL-E by 8.42 and 8.07 points over L2-only training.

-## 📢 What's New
-
-- **[2026.09.07]** The [***UltraData-Code***](https://huggingface.co/datasets/openbmb/UltraData-Code) dataset is released! It is a complete implementation of the [UltraData](https://ultradata.openbmb.cn/) [L0-L4 tiered data management framework](https://arxiv.org/pdf/2602.09003). It covers four code data states from L0 through L3, with each level corresponding to a distinct construction stage. This release currently open-sources **L2** (\~400B tokens) and **L3** (\~150B tokens) across 11 programming languages. 🚀🚀🚀
-- **[2026.09.07]** ***[MiniCPM5-2B](https://huggingface.co/openbmb/MiniCPM5-2B) is released!***, the second model in the MiniCPM5 series after MiniCPM5-1B. It is a dense 2B Transformer that scales up the same training recipe, built for on-device, local deployment, and resource-constrained scenarios. It reaches **2B-class open-source SOTA**, remains competitive with 4B-class models, and shows particular advantages in coding, mathematics, long-context understanding, tool use, and agentic tasks. UltraData-RL-2609 serves as the core RL dataset for MiniCPM5-2B. 🚀🚀🚀
-- **[2026.02.08]** The [***UltraData***](https://ultradata.openbmb.cn/) platform is now live, introducing the [L0-L4 tiered data management framework](https://arxiv.org/pdf/2602.09003).  🔍🔍🔍

-## 💡 Highlights
-
-> **Abstract:** Code generation has become a core capability of large language models, and code data is a central part of the pre-training process that develops it. As code corpora continue to grow, their scale, diversity, and quality increasingly shape the capabilities learned during pre-training. Following a tiered data management perspective, we present **UltraData-Code** as a family of four connected data states, from repository archival at L0 through standardized natural code at L1, algorithmic selection at L2, and task-oriented synthesis at L3. L0 archives the latest revision on the default branch of each public GitHub repository with its file structure, relationships, and provenance. L1 applies scalable filtering, normalization, and near deduplication to obtain standardized natural code. L2 then selects algorithmically relevant files from L1 using language-adaptive signals from file roles and heuristics, together with code quality constraints, yielding approximately 400B tokens of **UltraData-Code-L2**, spanning 11 programming languages. L3 applies task-oriented synthesis to algorithmic files from L2, turning each implementation into a structured programming exercise, generating approximately 150B tokens of **UltraData-Code-L3** in the same 11 languages. Under controlled 10B-token continual pre-training of a 1B model, training on L2 instead of L1 raises pass@1 on EvalPlus by **7.80 points** and on MultiPL-E by **5.13 points**, while exceeding Stack-Edu by 4.37 and 3.05 points, respectively. Replacing half of the L2 training tokens with L3 yields a further gain of **8.42 points** on EvalPlus and **8.07 points** on MultiPL-E over L2-only training, while exceeding the strongest synthetic data baseline by 5.57 and 7.80 points, respectively. When the training budget increases to 100B tokens, gains from L2 selection and L3 synthesis further widen on both benchmarks.
