{"library":"openai-harmony","type":"library","category":null,"description":"OpenAI Harmony is a Python library providing a renderer for OpenAI's 'Harmony' response format, specifically designed for its open-weight model series, gpt-oss. It enables structured conversations, reasoning output, and function calls, mimicking the OpenAI Responses API. The library, with a Rust core and Python bindings, ensures consistent formatting, efficient processing, and first-class Python support, including typed stubs. It is crucial for developers building inference solutions for gpt-oss models, as these models are trained on and require the Harmony format for correct operation.","language":"python","status":"active","version":"0.0.8","tags":["openai","LLM","response-format","gpt-oss","AI","Rust-backed"],"install":[{"cmd":"pip install openai-harmony","imports":["from openai_harmony import load_harmony_encoding","from openai_harmony import HarmonyEncodingName","from openai_harmony import Role","from openai_harmony import Message","from openai_harmony import Conversation","from openai_harmony import DeveloperContent","from openai_harmony import SystemContent"]}],"homepage":null,"github":null,"docs":null,"changelog":null,"pypi":"https://pypi.org/project/openai-harmony/","npm":null,"openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"3.10–3.9","success_rate":100,"avg_install_s":3.3,"avg_import_s":0.6,"wheel_type":"wheel"},"url":"https://checklist.day/v1/registry/openai-harmony/compatibility"},"provenance":{"verified_status":"passing","verified_at":"Sun Jun 28","last_verified":"Sun Jun 28","next_check":"Tue Jul 28","install_tag":null}}
