Problem statement & goal
The paper states what problem it solves and what new idea it introduces. Skim the abstract and introduction for the one-sentence pitch before you read the math.

Methodology & architecture
This section is the “how it works” story: the model design, training recipe, and data pipeline. Follow the main figure first, then fill in details from the text.
Datasets & benchmarks
Authors list what data they trained and tested on and which standard benchmarks they compare against. Check that comparisons are fair (same data, same rules).
Results & evaluation metrics
Here you find the numbers and plots that back the claims—accuracy, loss, human evaluation, etc. Ask whether gains are large enough to matter in practice.
Limitations & future work
Good papers admit weaknesses: where the method breaks, what data or compute it needs, and what is left for future work. That’s what you’d hit in a real project.
Related work
This part situates the work among older papers—what existed before and what is genuinely new. It helps you cite correctly and explain the idea in interviews.
Reproducibility
Look for hyperparameters, training setup, code links, and appendices. You’ll see whether you could rerun the experiment without guessing missing details.
What to focus on
Eight highlights per paper—why each part matters before you read dense notation and proofs.
Self-supervised API calls
Model learns where to insert calls to calculators, QA APIs, translators via annotated corpora generated by the LM itself.
Sparse delegation
Only some tokens trigger tools—mirrors selective routing in enterprise agent gateways.
Reward shaping
Loss encourages helpful calls without exploding compute—critical theme for practical agents.
Comparison to plugins
Conceptually aligns with ChatGPT plugins / function calling—historical blueprint for structured tool schemas.
Security lens
Every external tool expands attack surface—sandboxing & auth mirrors prod AI platforms.
Data freshness
Unlike parametric memory, APIs fetch live signals—trade-offs vs latency & reliability.
Annotation overhead
Bootstrapping supervision remains costly—later RL pipelines automate preference shaping.
Agentic AI framing
Shows language-only controllers orchestrating heterogeneous backends—the vibe of "professional-grade" assistants.
