Build an AI Changelog Generator in Python

Writing changelogs is one of those developer tasks that sounds simple until you are staring at a messy commit history. Some commits matter to users. Some are internal cleanup. Some are merge commits. Some are meaningful only if you already know the codebase. I built a small Python example that turns commit messages or git diffs into structured changelog JSON using Telnyx AI Inference. Code: https://github.com/team-telnyx/telnyx-code-examples/tree/main/changelog-generator-python What it does The Flask app exposes: POST /generate POST /generate/from-diff GET /changelogs GET /changelogs/<id> GET /health POST /generate accepts a list of commit messages: { "version" : "v1.4.0" , "repo_name" : "billing-service" , "commits" : [ "feat: add Stripe webhook retry with exponential backoff" , "fix: correct tax calculation for EU VAT exemption" , "docs: update API reference for invoice endpoint" ] } The app asks Telnyx AI Inference to return grouped changelog JSON with sections like: Features Bug Fixes Improvements Breaking Changes Documentation Other There is also a POST /generate/from-diff endpoint if you want to summarize a git diff instead of commit messages. Why structured output matters For a changelog tool, plain text is useful, but structured output is more flexible. If the response comes back as JSON, you can: render it in a docs site save it in a release database post it into a PR comment send it to Slack open a release-note review workflow let a human approve it before publishing The example stores generated changelogs in memory and gives each one an ID, so you can list recent changelogs or retrieve a specific one. Run it Clone the examples repo: git clone https://github.com/team-telnyx/telnyx-code-examples.git cd telnyx-code-examples/changelog-generator-python Create your .env file: cp .env.example .env Add your Telnyx API key: TELNYX_API_KEY=your_telnyx_api_key AI_MODEL=moonshotai/Kimi-K2.6 HOST=127.0.0.1 Install and run: pip install -r requirements.txt python app.py
