Apparently, you can build tiny reasoning models via LoRA.
Tina is a family of 1.5B models trained using LoRA-based RL—cost-efficient and performant.
The best Tina hits >20% gain in reasoning performance and 43% Pass@1 on AIME24,
with just $9 in post-training + eval cost.

Prompt Evaluation and Optimization: Continuous Iteration
By
–
5/ Evaluation & Optimization Prompts aren’t “set it and forget it.” They A/B test, evaluate, and refine. They track hallucinations, latency, cost, and safety. Prompt engineers treat prompts like software always in iteration.

Product Thinking: Designing Prompts for Real Use Cases
By
–
4/ Product Thinking They design prompts with real use cases in mind. AI isn’t just for demos. It powers: • Customer support
• Internal tools
• Research agents
• Creative workflows Prompts must work inside real products and systems. -
Model Fluency: How prompt engineers adapt to LLM quirks
By

3/ Model Fluency They’re fluent in LLMs: • GPT-4
• Claude
• Mistral
• Gemini
• HuggingFace OSS models Each behaves differently. Prompt engineers tune to model quirks like a developer tunes to APIs. Different models, different logic. -
Language Design with Proven Frameworks for Reasoning and Output
By
–
2/ Language Design They use proven frameworks — not guesswork. • Chain of Thought
• ReAct (Reason + Act)
• Tree of Thought
• RAG (Retrieval-Augmented Generation)
• Few-shot prompts These guide reasoning, structure, and output control. It’s language as architecture. -
Translation Layer: Prompt Engineering as Strategic Communication
By
–
1/ Translation Layer Prompt engineers translate human goals into precise instructions. They break down abstract tasks into structured input. This gives the model the context it needs to deliver useful, relevant output. Prompting = strategic communication.
