Inglés para trabajar con IA: prompts, LLMs y pair programming en inglés
22 de septiembre de 2026
Por qué los mejores prompts de IA son en inglés, el vocabulario que necesitas, y cómo hablar de tu trabajo con IA con tu equipo.
Puntos clave
- Los prompts en inglés producen mejores resultados en la mayoría de LLMs porque los modelos son entrenados principalmente en texto en inglés.
- Conocer el vocabulario de IA correcto te permite hablar de tu trabajo con claridad con tu equipo.
- El pair programming con IA requiere frases específicas en inglés para obtener resultados útiles y precisos.
- Siempre verifica los outputs de IA: las alucinaciones son comunes, especialmente en detalles técnicos.
- La documentación de IA está en inglés. Aprender a leerla más rápido es una habilidad de alto impacto.
Why prompts work better in English
Por qué los prompts funcionan mejor en inglés
The majority of text used to train large language models is in English. This means that for technical tasks, such as writing code, reviewing architecture, or debugging, English prompts tend to produce more precise and detailed responses.
This isn't a rule without exceptions. Models have improved significantly in Spanish and other languages. But for technical content specifically, the gap still exists. A prompt like “Write a Go function that implements a rate limiter using the token bucket algorithm” will consistently outperform a Spanish equivalent in most current models.
Practical test you can run right now:
Ask the same technical question in English and in Spanish. Compare the depth and accuracy of the response. For most complex coding questions, the English response will be more detailed and technically accurate.
AI vocabulary for developers in English
Vocabulario de IA para developers en inglés
These are the terms you need to discuss AI work in English with your team. Many have no direct Spanish equivalent and are used as-is in Spanish-language tech conversations.
| Term | Español | Example sentence |
|---|---|---|
| Prompt | Instrucción / consulta | Write a clear, specific prompt to get a useful response. |
| Token | Token | GPT-4 has a context window of 128k tokens. |
| Context window | Ventana de contexto | The context window limits how much text the model can process at once. |
| Hallucination | Alucinación | The model hallucinated an API method that doesn't exist. |
| Fine-tuning | Ajuste fino | We fine-tuned the model on our internal codebase. |
| Embedding | Embedding / representación vectorial | Embeddings let us search semantically across our documentation. |
| RAG | RAG (Retrieval-Augmented Generation) | We built a RAG pipeline so the model can answer questions about our codebase. |
| Inference | Inferencia | Inference cost is the main operational expense for LLM applications. |
| Temperature | Temperatura | Set temperature to 0 for deterministic outputs. |
| System prompt | Prompt de sistema | The system prompt defines the model's behavior and constraints. |
| Few-shot prompting | Prompting con ejemplos | Provide 2-3 examples in your prompt to guide the model's output format. |
| Chain of thought | Cadena de razonamiento | Ask the model to think step by step for complex reasoning tasks. |
| Grounding | Fundamentación | Grounding prevents hallucinations by anchoring responses to real data. |
| Guardrails | Barreras / restricciones | We added guardrails to prevent the model from generating harmful content. |
| Multimodal | Multimodal | GPT-4V is multimodal: it can process both text and images. |

How to pair program with AI in English: useful phrases
Cómo hacer pair programming con IA en inglés: frases útiles
Effective AI pair programming requires specific English phrases. The more precise your prompt, the more useful the response. These phrases work across Copilot, Claude, and ChatGPT.
“Write a function that...”
Starting point for any code generation task.
“Refactor this to use...”
Ask for a specific pattern or data structure.
“Explain what this code does.”
Get a plain-English explanation of unfamiliar code.
“What are the edge cases here?”
Ask the model to think about what your code might miss.
“Is there a more idiomatic way to write this?”
Get language-specific best practices.
“Why did you choose this approach?”
Understand the reasoning, not just the code.
“This looks like it has an O(n²) complexity. Can you optimize it?”
Challenge the model to improve time complexity.
Example: a full pair programming session in English
You: “Write a Python function that validates an email address.”
[AI generates code]
You: “What are the edge cases this doesn't handle?”
[AI lists edge cases]
You: “Refactor this to use a compiled regex for better performance.”
[AI refactors]
You: “Is there a more idiomatic way to write this in Python?”
How to discuss AI work with your team in English
Cómo hablar de tu trabajo con IA con tu equipo en inglés
When you discuss AI-generated work with your team in English, you need phrases that communicate both what the AI did and what you verified. Transparency about AI involvement is becoming standard practice.
“I used Copilot to scaffold this but reviewed every line.”
“The model hallucinated this part. I need to verify it.”
“Let's add a human review step before shipping this AI output.”
“The prompt needs more context about our domain.”
“This is a false positive from the classifier.”
Notice the pattern: these phrases communicate your role in verifying and adapting AI output. They show professional judgment, not blind reliance on the tool.
AI tools documentation is in English: how to read it faster
La documentación de herramientas de IA está en inglés: cómo leerla más rápido
AI tools like the OpenAI API, Anthropic Claude, Google Gemini, and LangChain all publish their documentation in English. Reading it efficiently is a skill in itself.
Strategy: examples first, explanation second
Skip to the code examples first. Once you see what the code does, the surrounding explanation makes much more sense. This works for any technical documentation in English.
Common doc patterns you need to recognise:
Deprecated
This feature still works but will be removed in a future version. Stop using it now.
Experimental
The API may change without notice. Don't use this in production.
Breaking change
Upgrading to this version will break existing code. Read the migration guide.
Under the hood
An informal phrase meaning 'how it works internally'. Usually precedes an explanation of implementation details.

Roxana Lafuente es ingeniera de software con más de 8 años de experiencia. Al comienzo de su carrera, aunque ya había aprobado el First Certificate in English, se bloqueaba cada vez que tenía que hablar en el standup diario. Era un problema que nadie estaba resolviendo. Después de más de 2.000 standups, descubrió qué es lo que realmente construye la fluidez: practicar situaciones que se parecen a tu trabajo real. Creó Lingua-e para que otros developers no tuvieran que tomar el camino largo para sentirse seguros trabajando en un entorno de desarrollo internacional.
