About this model

GPT-oss-120b is the most powerful open-weight model. A 120B-parameter open-weight Mixture-of-Experts model delivering state-of-the-art reasoning, coding, and tool-use performance

Best suited for

Production, general purpose, high reasoning use cases.

Built-in tools

Gtwy web search

Hosted by the gateway — enable them per request without wiring your own endpoint.

Capabilities

Tools

Native function calling, so agents can invoke your endpoints.

System prompt

Honours a dedicated system role, separate from the user turn.

Supported parameters

creativity_level

Controls the creativity of responses. Higher values (e.g., 0.7) increase creativity; lower values (e.g., 0.2) make responses more predictable.

max_tokensMax Tokens Limit

Specifies the maximum number of text units (tokens) allowed in a response, limiting its length.

probability_cutoffProbability Cutoff (Top P)

Focuses on the most likely words based on a percentage of probability.

repetition_penalty

The `frequency_penalty` controls how often the model repeats itself, with higher positive values reducing repetition and negative values encouraging it.

novelty_penalty

Discourages responses that are too similar to previous ones.

stop

This parameter tells the model to stop generating text when it reaches any of the specified sequences (like a word or punctuation)

tools

Lists tool definitions or capabilities available to the model.

tool_choice

Decides whether to use tools or just the model for generating responses.

parallel_tool_calls

Enables parallel execution of tools, allowing multiple tools to run simultaneously.

response_type

Defines the format or type of the generated response.

stream

Sends the response in real-time as it's being generated.

Use this model

OpenAI-SDK compatible, with gateway fallback and routing across providers.
