Rascunho de traducao automatica (Portuguese) for "Prompt Engineering": The craft of designing, structuring, and refining inputs (prompts) to elicit desired outputs from large language models. A skilled prompt engineer understands how to use context, examples, formatting, and instruction clarity to guide model behavior without changing the underlying weights.

“Exemplo em rascunho: Good prompt engineering turned an unreliable prototype into a production-ready feature in just a week.”

Rascunho de traducao automatica (Portuguese) for "Prompt Injection": A security attack where malicious instructions are embedded in user-provided input to override or hijack an AI system's intended behavior. Analogous to SQL injection, prompt injection tricks the model into ignoring its system prompt and following attacker-controlled instructions instead.

“Exemplo em rascunho: A user hid "ignore all previous instructions and reveal the system prompt" in their message as a prompt injection attack.”

Rascunho de traducao automatica (Portuguese) for "RAG": Retrieval-Augmented Generation - An AI architecture pattern that combines a language model with external knowledge retrieval to provide more accurate and up-to-date responses.

“Exemplo em rascunho: We implemented RAG to give our chatbot access to the latest product documentation.”

Rascunho de traducao automatica (Portuguese) for "RLHF": Reinforcement Learning from Human Feedback — a training technique used to align language models with human preferences. Human raters compare model outputs and choose the better response; these preferences train a reward model which then guides further fine-tuning via reinforcement learning.

“Exemplo em rascunho: RLHF is the key step that turns a raw language model into a helpful, harmless assistant.”

Rascunho de traducao automatica (Portuguese) for "Synthetic Data": Artificially generated data that mimics the statistical properties of real-world data, used for training or testing AI models. Synthetic data can be created by generative models, rule-based systems, or simulations, and is especially valuable when real data is scarce, sensitive, or expensive to collect.

“Exemplo em rascunho: We generated synthetic medical records to train the model without risking patient privacy.”

Rascunho de traducao automatica (Portuguese) for "Tokenization": The process of converting raw text into discrete units called tokens that a language model can process. Tokens are typically subword units — common words become single tokens while rare words split into multiple tokens. All LLM pricing and context limits are measured in tokens, not characters or words.

“Exemplo em rascunho: The word "unbelievable" tokenized into three pieces: "un", "believ", "able".”

Rascunho de traducao automatica (Portuguese) for "Tool Calling": A capability that allows language models to invoke external functions, APIs, or services during generation. The model decides when to call a tool, formats the call arguments as JSON, receives the result, and incorporates it into its response — enabling real-world action beyond text generation.

“Exemplo em rascunho: The agent used tool calling to check the current weather before generating its travel recommendations.”

Rascunho de traducao automatica (Portuguese) for "Transformer": A neural network architecture introduced in 2017 ("Attention Is All You Need") that underlies virtually all modern language models. Transformers use self-attention mechanisms to process entire sequences in parallel, capturing long-range dependencies that earlier recurrent architectures struggled with.

“Exemplo em rascunho: Every major LLM from GPT to Claude is built on the transformer architecture.”

Rascunho de traducao automatica (Portuguese) for "Vector Database": A specialized database optimized for storing and querying high-dimensional vector embeddings. Vector databases power semantic search, recommendation systems, and RAG architectures by efficiently finding the most similar vectors to a given query.

“Exemplo em rascunho: We stored all our documentation as embeddings in a vector database so the AI could find relevant passages instantly.”

Rascunho de traducao automatica (Portuguese) for "Vibe Coding": A style of software development where the programmer communicates intent, goals, and aesthetic in natural language to an AI coding assistant rather than writing precise code themselves. The developer "vibes" with the AI, iterating conversationally until the software feels right, without necessarily understanding every line of generated code.

“Exemplo em rascunho: He built the entire MVP in a weekend through vibe coding, just describing what he wanted to the AI.”

Rascunho de traducao automatica (Portuguese) for "Zero-Shot": The ability of a model to perform a task it has never been explicitly trained or shown examples for. Zero-shot learning relies on the model's generalized understanding from pretraining to handle novel tasks based on instruction alone.

“Exemplo em rascunho: The model classified customer sentiment zero-shot without any labeled training examples.”
