Which is cheaper, GPT-5.6 Cyber or GPT OSS 120B?
As of August 20, 2026, GPT OSS 120B is 99% cheaper on blended LLM API pricing. GPT OSS 120B costs $0.09 per million input tokens and $0.45 per million output tokens ($0.54 blended 1M-in + 1M-out). GPT-5.6 Cyber costs $12.50 / $75.00 per million tokens ($87.50 blended). Sources: https://developers.openai.com/api/docs/pricing and https://developers.openai.com/api/docs/pricing. The cheapest LLM for your app still depends on how many output tokens you generate.
How much does GPT-5.6 Cyber vs GPT OSS 120B cost per million tokens?
GPT-5.6 Cyber OpenAI API pricing is $12.50 input and $75.00 output per million tokens via OpenAI. GPT OSS 120B OpenAI API pricing is $0.09 input and $0.45 output per million tokens via OpenAI. Use those four numbers, not ChatGPT Plus or Claude Pro subscription prices, when you are comparing APIs.
Which is better for coding, GPT-5.6 Cyber or GPT OSS 120B?
GPT OSS 120B has a published SWE-bench Verified score of 33.6%. GPT-5.6 Cyber does not have that eval on this page yet.
What is the context window for GPT-5.6 Cyber vs GPT OSS 120B?
GPT-5.6 Cyber supports a 400K token context window, while GPT OSS 120B supports 131K tokens. GPT-5.6 Cyber offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Which model performs better on benchmarks, GPT-5.6 Cyber or GPT OSS 120B?
Shared benchmark scores for GPT-5.6 Cyber and GPT OSS 120B are still limited. Check the comparison table for the evals each model has published. Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.
Is GPT-5.6 Cyber or GPT OSS 120B better for production use?
Both GPT-5.6 Cyber and GPT OSS 120B are production API models. For cost-sensitive production traffic, GPT OSS 120B has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain. Many production stacks route cheap models for drafts and a frontier model for the hard turn, which is usually cheaper than sending everything to the expensive API.
Can I switch between GPT-5.6 Cyber and GPT OSS 120B in my app?
Yes. Call GPT-5.6 Cyber through OpenAI and GPT OSS 120B through OpenAI with separate API keys, or through a gateway that already wraps both. Keep prompts in tokens, not characters, when you estimate the invoice. AnotherWrapper templates can swap providers without rewriting auth and billing.
How accurate is this GPT-5.6 Cyber vs GPT OSS 120B pricing data?
List rates are the latest published OpenAI API pricing and OpenAI API pricing, quoted per million tokens. Official rate sheets: https://developers.openai.com/api/docs/pricing and https://developers.openai.com/api/docs/pricing. Prompt caching, batch APIs, and committed-use discounts can change the invoice. Benchmark scores are from official publications and independent evals, updated as new numbers land.
What is the output token limit for GPT-5.6 Cyber and GPT OSS 120B?
GPT-5.6 Cyber supports up to 128K output tokens per request, while GPT OSS 120B supports up to 131K output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
Which model has better throughput, GPT-5.6 Cyber or GPT OSS 120B?
Neither GPT-5.6 Cyber nor GPT OSS 120B has published throughput data on this page yet. Throughput (tokens per second) and time-to-first-token are why two models with the same per-million-token price can still feel different in chat and agents.
How do I switch the models in this GPT-5.6 Cyber vs GPT OSS 120B comparison?
Use the model pickers at the top of this LLM comparison. Search any model in the index and the URL updates. Open GPT-5.6 Cyber or GPT OSS 120B from the sidebar for the single-model API pricing page, or go back to the LLM pricing table to sort by cheapest blended cost.
