GPT-5.4: The First General-Purpose Model Built to Operate Computers GPT-5.4 is OpenAI's frontier model that folds the GPT-5.3-Codex coding line back into the mainline, unifying reasoning, coding, and agentic workflows in one system. It is positioned as OpenAI's most capable model for professional, document-heavy work. Its defining feature is native computer use: GPT-5.4 operates desktop applications from screenshots and keyboard/mouse actions, reaching a state-of-the-art 75.0% on OSWorld-Verified. Combined with a 1M-token context window and tool search, it targets long-horizon agents that plan, execute, and verify tasks across software, spreadsheets, and documents with less manual intervention. Access GPT-5.4 via the AnyAPI.ai API and start building computer-use agents.

Questions

Answers to common questions about integrating and using this AI model via AnyAPI.ai

GPT-5.4 has a 1,050,000-token context window with a maximum output of 128,000 tokens. Prompts exceeding 272K input tokens are priced at 2x input and 1.5x output for the full session, so very large-context requests carry meaningfully higher cost.

GPT-5.4 is OpenAI's first general-purpose model with native, state-of-the-art computer use, scoring 75.0% on OSWorld-Verified and surpassing the reported 72.4% human baseline. It unifies coding, reasoning, and agentic workflows in one model, folding the GPT-5.3-Codex coding line back into the mainline.

Yes. GPT-5.4 scores 57.7% on SWE-Bench Pro (Public), slightly ahead of the coding specialist GPT-5.3-Codex at 56.8%, while adding computer use and a 1M-token context. For narrowly terminal-agent coding, GPT-5.3-Codex still holds a small edge on Terminal-Bench 2.0.

Yes. GPT-5.4 exposes a reasoning-effort control with medium (default), high, and xhigh settings. It supports tool calling with tool search, structured outputs via JSON schema, prompt caching, and native computer use through the OpenAI Responses API.

GPT-5.4 accepts text and image input and produces text output. Its knowledge cutoff is August 31, 2025. Unlike some sibling or consumer models, it is a text-output model, so it does not natively generate images or audio through this API model.
