Harmony

gpt-oss does not use ChatML; instead it is trained on OpenAI's Harmony format, outputting content through three channels: analysis, final, and commentary.

In the Harmony format, the final answer ends with <|return|>, messages in the conversation history end with <|end|>, and <|return|> must be set as a stop token, otherwise generation will continue indefinitely.

Harmony's agents can actually execute actions—such as directly resetting passwords and provisioning SaaS application access—rather than merely directing users to help documentation.

Only when human intervention is genuinely needed will a request be escalated and handed off to a human, following an AI-first, human-fallback model.

Harmony officially claims that teams that integrate it can achieve an automated resolution rate of over 60% within days.

Harmony is an AI-native ITSM platform for IT teams where employees can ask questions directly in Slack or Microsoft Teams, with built-in agents handling requests end-to-end.

When Harmony launched on Product Hunt, it received 103 votes and 8 comments, ranked fifth, and was categorized under three tracks: Productivity, SaaS, and Artificial Intelligence.

Harmony co-founder Nitzan Shapira has entrepreneurial experience in the developer tools and observability space.

Harmony consolidates ticket management, asset inventory, SaaS management, and workflows into a single workspace.

Harmony provides more than 100 production-ready agents covering high-frequency scenarios such as password resets, application access permissions, employee onboarding, and device issues.
