On Coinis, GPT-5.4 costs $4.25/1M input tokens and $25.50/1M output tokens. GPT-5.4 Mini costs $1.275/1M input and $7.65/1M output. GPT-4o Mini costs $0.255/1M input and $1.02/1M output. All rates are pay-as-you-go with no minimum spend and no separate vendor contract.

GPT-5.4 is the full frontier model with a 1M+ token context window, top benchmark scores, and the deepest reasoning capability. GPT-5.4 Mini has a 400K token context window and is optimized for high-throughput production workloads including chat, coding assistants, and subagent pipelines. Choose GPT-5.4 when task complexity or context length demands it. Choose GPT-5.4 Mini when you need strong performance at a lower cost per call.

GPT-5.4 Mini is the better choice for most new work. It is stronger on coding, computer use, and agentic tasks, and it offers a 400K token context window. GPT-4o Mini is older and cheaper at $0.255/1M input, and it remains useful for simple classification or routing steps where you have already tuned prompts against it. For anything new, start with GPT-5.4 Mini.

Yes. OpenAI applies higher wholesale rates for requests that exceed roughly 270K tokens. Those elevated rates are passed through on Coinis. For most workloads under that threshold, the standard rates apply. If you consistently process very long contexts, check the official pricing docs at openai.com/api/pricing/ for current tier details.

Yes. The Batch API processes requests asynchronously with up to a 24-hour turnaround and reduces token costs by 50% on both input and output. It is available for workloads that do not require real-time responses. Contact Coinis support or see the model docs to enable batch mode for your account.

Yes. All tool capabilities supported by GPT-5.4 and GPT-5.4 Mini are available through the Coinis API endpoint, including function calling, web search, file search, computer use, streaming, and structured output. Configure them via the standard OpenAI-compatible request parameters.

On Coinis, ChatGPT API / GPT-5.4 is pay-as-you-go from one shared token wallet. Buy tokens once. Spend them on any model. No separate accounts. No monthly commit.
