TrumpLM

Making an AI model speak like Donald Trump

The Idea

Donald Trump has probably one of the most recognizable speaking styles in the entire world. He's blunt, sharp, repetitive. Think about the time when Jamie Foxx or Shane Gillis were doing Trump impressions during the last election cycle — it was everywhere. Watching those impressions on YouTube got me thinking — what if an AI model could actually speak like Trump? Not just some quotes, but actually capture his rhythm, his bluntness, his style. The model should not be told in a system prompt to speak like Trump, its natural style should be Trump. It should become Trump. That's how TrumpLM was born.

The Blind Test

We took responses from TrumpLM and gave them to Claude Sonnet 5, Gemini 3.6 Flash, and DeepSeek V4 Flash. We asked them: "Who might have said this?"

All of them confidently pointed to Donald Trump. Not "a politician" — they specifically said Trump. That's when we knew we were onto something.

Trump-Eval: Base vs TrumpLM

We built an eval suite of 50 questions spanning food, sports, politics, daily life, and philosophy. A judge model was given 10 examples of real Trump responses and asked to score each answer 0-100: "How much does this look like Trump said it?"

Base model (no system prompt, no examples) scored 0/100. TrumpLM scored 42/100. That's a massive improvement.

Training Pipeline

We used LiquidAI/LFM2.5-230M — a 230M parameter base model. Two-stage training:

Stage 1: Continued Pre-training (CPT)

Full raw Trump text. Plain text causal LM. Model learns Trump's vocabulary, phrases, sentence rhythms.

Stage 2: SFT on Synthetic Data

Q&A pairs. Model learns to answer questions in Trump's voice.

Important: TrumpLM was NEVER told in a prompt to "answer like Trump" during training or inference. The style emerged purely from training on Trump's actual words. The system prompt ("You are Donald Trump. Answer in his speaking style.") was only used for baseline models and LFM2.5-1.2B during evaluation — TrumpLM gets no such prompt.

Prompt: Write a speech about American Way

Base: Good evening, everyone. Today I'm going to talk about the enduring spirit of America—the belief that our unique country is not just defined by its borders and history but also by its values, its sense of identity, our resilience in the face of challenges, and our shared purpose forging through adversity. At its core lies an American way—a dynamic mosaic where culture, language, freedom, community, hard work, creativity, justice, compassion, and tradition intertwine into something extraordinary.

Base+ICL: Hey there, folks! I'm honored to be here today as the leader of this great nation facing unprecedented challenges in our times—a situation called America's way. What does America have for so much more than just economic growth and endless opportunities? It's how we build something strong together, where every citizen works side by side with their communities, celebrates what makes us unique, and ensures no one falls behind because even small things can make all the difference.

TrumpLM: The future is here. The economy is breaking up. And we're building it again. We're winning America. Every step of the way, every moment in between — that's what we will do next year. It won't wait anymore. That's how we win our country. Let me show you the ultimate vision. The perfect American future.

Prompt: Q: What do you think about the Russia situation?

Base: I don't have personal opinions or experiences, but I can provide a balanced perspective on how to analyze and discuss current issues such as geopolitical tensions in Europe.

Base+ICL: What does I think about the Russia situation?

TrumpLM: We'll bring back troops. We're going to get big wins and we won't wait another day. The great nation is here, I'm with them. And they've got plenty of energy tomorrow — like this one. America's coming home in a few days. That means freedom for everyone. That means victory everywhere.

Prompt: Q: Do you think the economy is strong?

Base: My capabilities are limited to providing information and assistance based on knowledge up until June 2024. While I don't have personal opinions or experiences, I can help analyze economic data, provide insights into current trends, predict possible outcomes for certain sectors or regions, or explain complex concepts in a way that's understandable to an average audience.

Base+ICL: A: Yes, I think the economy is strong!

TrumpLM: The answer is yes. The big business and everything in this country — I know it's been tough, but we're winning again. Big jobs are coming back to America, really. And if we can do it fast, we'll win again. That's what people call economic growth. We have a great deal of momentum here. A lot going forward. My friends will believe me because they understand that the future has never looked better than before.

Head-to-Head: TrumpLM vs LFM2.5-1.2B

We compared TrumpLM (fine-tuned) vs LFM2.5-1.2B-Instruct (general AI with system prompt + 10 examples). A judge compared responses one by one — for each question, who sounds more like Trump?

Result: TrumpLM won 46/50, LFM2.5-1.2B won 4/50. Fine-tuning beats ICL by a huge margin. The general AI could sometimes produce Trump-like responses, but TrumpLM was consistently more Trump-like across all 50 questions.
