gpt-oss-120b
gpt-oss-120b is an open-weight, 117B-parameter Mixture-of-Experts (MoE) language model from OpenAI designed for high-reasoning, agentic, and general-purpose production use cases. In StickyPrompts it sits in the same model selector as every other model your workspace allows. Your prompts, knowledge bases and guardrails work with it unchanged, and switching to it is one click in the chat.

Capabilities, as the provider publishes them.
Taken from the provider's own model metadata rather than our impressions of it. What we do not publish is a quality or speed score - those are measurements, and we do not run them.

Output tokens cost 4x input on gpt-oss-120b. Worth knowing before you give it a long-running agent job. StickyPrompts meters both, and Usage Statistics breaks the spend down by model and by user.
The model changes. The workspace around it does not.
New models ship every few weeks. When your prompts, knowledge and rules live in one workspace, moving to a better model is a choice in a dropdown rather than a migration.
- One login, one prompt library and one usage record across every model
- Knowledge bases, agents and connected tools work the same whichever model answers
- Admins allow, block or limit each provider per team in Model & Provider Access
- Sensitive data is warned about, redacted or blocked before it reaches any model
- Optional EU-only inference and zero-data-retention constraints, applied to the whole catalogue
- Compare two to five models on the same prompt before you settle on one

Other checkpoints from the same maker, with the ones in StickyPrompts marked.
Specifications synced 29 Sept 2026 from the OpenRouter public model catalogue; availability in StickyPrompts checked 29 Sept 2026. Providers change prices and deprecate checkpoints without much notice, so check the provider's own documentation before making a commercial decision on these figures.
