GPT 5.4: capabilities, context and price

Tavory's live catalog lists GPT 5.4 through OpenAI. The route is described as gpt-5.4 is openai's latest frontier model, unifying the codex and gpt lines into a single system. it features a 1m+ token context window (922k input, 128k output) with support for text and image inputs, enabling high-context reasoning, coding, and multimodal analysis within the same workflow. the model delivers improved performance in coding, document understanding, tool use, and instruction following, capable of generating production-quality code, synthesizing information across multiple sources, and executing complex multi-step workflows with fewer iterations and greater token efficiency.. This page summarizes the current catalog facts so you can compare context, capabilities and provider price signals before opening a workspace request. Availability, plan access and final cost are checked again when you send. Tavory consolidates 3 equivalent regional or provider routes on this canonical page to keep the comparison useful and avoid duplicate model listings.

GPT 5.4 is represented in Tavory for text and chat, reasoning and analysis, document work, image understanding, web research. Suitability still depends on the prompt and required capabilities.

If GPT 5.4 is eligible for your plan and a healthy route is available when you send, you can choose it in Tavory. Tavory is an independent workspace and is not the manufacturer of GPT 5.4.

$2.5 input / $15 output per 1M tokens is the current public catalog signal. Tavory checks the selected route and shows the applicable request cost; provider data can change.
