| Scenario | Cost | Assumption |
|---|---|---|
RAG answer per 1,000 RAG answers | $0.22 < $0.01 per request | 5K input tokens (query + 4 retrieved chunks of ~1K each) and a 500-token answer. Typical SaaS knowledge-base bot. |
Support ticket triage per 10,000 tickets | $0.44 < $0.01 per request | 1K input tokens (ticket body + system prompt) and a 100-token JSON classification reply. High-volume customer support. |
Data extraction per 1,000 documents | $0.13 < $0.01 per request | 2K input tokens (a single document page) and a 500-token JSON extraction. ETL / invoice / form pipelines. |
Code review per 1,000 PRs | $0.38 < $0.01 per request | 8K input tokens (diff + surrounding files) and a 1K-token review comment. PR-bot workloads. |
Agent step per 1,000 steps | $0.44 < $0.01 per request | 12K input tokens (long-running tool history) and a 600-token tool-call decision. Cost per agent step. |

Frequently asked questions
How much does GPT OSS 20B cost?
GPT OSS 20B costs $0.030 per 1M input tokens and $0.140 per 1M output tokens, sourced from deepinfra. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.
What is the context window of GPT OSS 20B?
GPT OSS 20B has a context window of 131K tokens, with a max output of 33K tokens per reply. This is the total combined size of prompt + completion.
Does GPT OSS 20B support tool calling?
Yes. GPT OSS 20B supports tool calling (function calling). This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Does GPT OSS 20B support structured output / JSON mode?
Yes. GPT OSS 20B supports structured output / JSON-schema-constrained decoding. This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Can GPT OSS 20B accept image input?
No. GPT OSS 20B only accepts text as input. If you need image input, see our /capabilities/vision list for current vision-capable models.
Is GPT OSS 20B open-weight?
Yes. GPT OSS 20B's weights are publicly available, so you can self-host or fine-tune. Note that open weights ≠ open source — the training data and code are typically not released.
What are the best alternatives to GPT OSS 20B?
If GPT OSS 20B doesn't fit, consider GPT OSS 120B, GPT-5.2, GPT-5 Mini. Each one targets the same use case — see the Related links below for direct head-to-head pages.
Where does this data come from?
All numbers come from the public models.dev API and are normalised into a single canonical model record. We re-pull daily and write any changes (price, context, capability) to the /changelog page.
