What is GPT-5.4?
GPT-5.4 is OpenAI's frontier text model released in March 2026, merging advanced reasoning, coding, and agentic tool-use capabilities. It supports up to 1 million tokens of context, vision and multiple image inputs, plus configurable reasoning effort for complex professional workflows.
Use it privately on Venice
On Venice, GPT-5.4 runs under an anonymized privacy tier with zero retention of your prompts — no training data harvesting, no profile building. You get the full frontier model with vision, reasoning, web search, and tool use, billed per token without a subscription. It is the same professional-grade model OpenAI ships, used permissionlessly and privately.
What can it do?
- •Multimodal frontier model supporting vision, multiple image inputs, reasoning, web search, and tool use for agentic workflows.
- •Configurable reasoning effort (none, low, medium, high, xhigh) lets you trade latency for depth on complex tasks.
- •Strong coding and professional-task performance for software environments and structured output.
- •1M-token context window supports large-scale document and codebase analysis.
- •Structured JSON output and function calling enable reliable multi-step automation.
- •Closed and proprietary — no open weights, self-hosting, or fine-tuning possible.
- •Inherits OpenAI's content policies and refusal patterns; not an uncensored model.
- •Very long-context reliability weakens in practice past a few hundred thousand tokens, so the full 1M window is better treated as workspace than perfect long-horizon memory.
- •Output pricing is significantly higher than open-weight rivals such as DeepSeek V3.2 or GLM 5.1.

OpenAI's most capable efficient frontier model for professional agentic work, with configurable reasoning and strong coding performance.
What is it good for?
- •Complex software development and coding agents with tool use.
- •Multi-step research combining web search, reasoning, and structured output.
- •Document and spreadsheet analysis with vision input and multiple image attachments.
- •Automated workflows across APIs and tools via function calling.
- •Professional writing and analysis requiring configurable reasoning depth.
Prompting tips
- •Set reasoning_effort to 'low' or 'none' for quick answers, and 'high' or 'xhigh' for deep analysis and coding.
- •Use the large context window for codebase or document batches, but verify key facts near the end of very long inputs.
- •Leverage function calling and web search for agentic workflows rather than relying on single-turn prompts.
- •Be explicit about tool sequences and desired structured outputs to reduce back-and-forth.

Frequently asked questions
GPT-5.4 is OpenAI's frontier text model released in March 2026. It merges advanced reasoning, coding, and agentic tool-use capabilities, supports vision and structured output, and offers a 1M-token context window with configurable reasoning effort.
Venice bills GPT-5.4 at $3.13 per 1M input tokens and $18.80 per 1M output tokens, with cached input at $0.31 per 1M. You pay per token with no subscription required.
No. GPT-5.4 is proprietary closed-source software from OpenAI. Its weights are not available for download or self-hosting. Open-weight alternatives on Venice include DeepSeek V3.2 and Kimi K2.6.
Yes. On Venice, GPT-5.4 supports function calling, tool use, web search, and structured JSON output, making it suitable for agentic workflows and multi-step automation.
Its training knowledge cutoff is August 31, 2025. For events after that date, you can pair it with Venice's web search capability to retrieve current information.
GPT-5.4 is generally more affordable and stronger at coding, tool-use agents, and deep web research. Claude Opus 4.7 tends to excel at nuanced reasoning and safety-critical analysis, but costs significantly more on Venice. Choose GPT-5.4 for agentic coding and Opus for deep analytical review.
No. GPT-5.4 retains OpenAI's built-in safety filters and refusal behaviors. Venice does not modify the model weights, so you get the standard OpenAI policy envelope. For uncensored outputs, explore open-weight models on Venice.
Venice runs GPT-5.4 under an anonymized privacy tier with zero retention — your prompts are not stored, profiled, or used for training. You use the same frontier model OpenAI ships, but without linking queries to a personal account history.
