I will custom dsa training data for llms python problems with cot reasoning
About this Gig
Train your coding LLM on production-grade DSA data not scraped LeetCode clones
I provide a premium, original Python DSA dataset built specifically for LLM training, fine-tuning, and evaluation. Each problem is a complete, self-contained training example not just a question and answer.
855+ unique coding problems, each including:
ComponentDescriptionPrompt
Detailed problem statement with constraints, input/output specs, and validation rules
Reasoning
Step-by-step chain-of-thought explaining approach, algorithm choice, and edge cases
Solution
Working Python implementation
Tests
Multiple test cases with assertions to verify correctness
Why this dataset is different
Most coding datasets online are:
- Scraped from public sources (copyright / duplication risk)
- Missing reasoning traces (bad for CoT / RLHF training)
- Trivial or repetitive (models memorize, don't generalize)
- Untested (solutions may be wrong)
Mine is built for AI training from the ground up:
- Original scenarios real-world styled problems (supply chain, network optimization, resource allocation), not copy-paste LeetCode titles
- Full reasoning chains ideal for training models that think before they code
- Verified solutions + test s
FAQ
Is this scraped from LeetCode or HackerRank?
No. Every problem is original with unique scenarios, constraints, and test cases. Safe for commercial LLM training.
What format do I receive?
Default is organized folders per problem. Standard and Premium include JSONL. Tell me your schema and I'll match it.
Can I use this to train a commercial LLM?
Premium includes a commercial training license. Basic and Standard are for evaluation and research unless we agree otherwise.
Does every problem include chain-of-thought reasoning?
Yes. Every problem has a dedicated reasoning file with step-by-step explanation before the solution.
Are solutions verified?
Yes. Each problem includes a test file with multiple assertions. Solutions are written to pass all tests.
Can I request specific topics?
Yes. Standard and Premium can include topic-filtered subsets (e.g. only graph problems, only DP).
What language are problems in?
Python. Problems specify function signatures and I/O. Other languages on request via custom order.
Can I see a sample before buying?
Message me and I'll send 2–3 sample problems (redacted) so you can review quality.
Do you sign NDAs?
Yes. NDA and exclusive licensing available as a gig extra.
Will you create new problems for my use case?
Yes. Custom problem creation is available as an add-on or separate gig.
