How this service works
GPT-OSS 120B — OpenAI's open-weight 120B. Reasoning at a low price.
Output
Returns a generated text completion from the GPT-OSS 120B open-weight model. The response contains the model's answer, reasoning, or generated content based on the provided prompt and optional system instructions, up to the specified max_tokens cap (default 1024, max 2048).
Example use cases
Complex multi-step reasoning task
“I need you to work through this logic puzzle step by step using the big 120B reasoning model: 'If all bloops are razzles, and all razzles are lazzles, are all bloops lazzles? Explain why.' Keep it under 500 tokens.”
Code generation for an agent pipeline
“Ask the GPT-OSS 120B model to write me a Python function that parses a nested JSON object and flattens it into a single-level dictionary with dot-notation keys. I want clean, commented code.”
Drafting a nuanced business document
“Use the open-weight 120B model to draft a concise executive summary for a SaaS product that helps restaurants reduce food waste using AI inventory forecasting — professional tone, max 400 tokens.”
Technical details
Endpoint
POSThttps://wafermap.xyz/v1/gpt-oss-120b?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a large open-weight model (120B parameters) with strong reasoning capabilities at a low per-call price ($0.00414 USDC). Prefer it over smaller models like DeepSeek Flash or Llama 4 Scout when the task involves complex multi-step reasoning, math, or nuanced generation. Prefer it over DeepSeek V4 Pro if you want OpenAI's model architecture specifically. Best when you need quality reasoning without committing to expensive proprietary API contracts.
Side effects
- Prompt exceeds 24,000 character limit — request rejected
- max_tokens set to 0 or negative — validation error
- System prompt exceeds 8,000 character limit — rejected
- Payment not attached or insufficient USDC — 402 Payment Required
- Model inference timeout for very complex reasoning chains
- Empty or whitespace-only prompt — minLength validation failure
