OpenAI released GPT-5.4 (Thinking and Pro), adding a 1M-token context window, native computer-use tooling, and SDK updates that reshape agent workflows and cost planning.
OpenAI rolled out GPT-5.4 across ChatGPT, the API, and Codex in two tiers, with Thinking for paid ChatGPT users and Pro for Pro/Enterprise, plus a 1M-token context and higher marginal costs beyond 272k tokens as reported by VentureBeat and detailed in OpenAI’s announcement. Early coverage also notes a newer August 31, 2025 knowledge cutoff and pricing slightly above 5.2 family levels, per Simon Willison.
For builders, GPT-5.4 introduces a native computer-use capability and tool search for more robust agents. The OpenAI Python SDK adds model and tool support in v2.25.0 and finalizes the GA ComputerTool and preview naming in v2.26.0, while the docs provide prompt and tool guidance under “Latest: GPT-5.4” and Tool Search in Prompt guidance.
Enterprise workflows get tighter spreadsheet loops via new integrations for Microsoft Excel and Google Sheets, enabling in-cell analysis and automation as covered by VentureBeat. Expect efficiency gains (fewer tokens on some tasks) and improved agentic browsing and computer control; tune prompts and safety rails per the updated developer guidance.
Agent capabilities move beyond API calls to real computer control, unlocking multi-app automations.
A 1M-token window enables longer plans and audits but forces stricter cost governance.

Benchmark 5.4 Thinking vs Pro on your agent tasks and instrument cost ceilings for long-context runs.
Legacy codebase integration strategies...
- 01.
Upgrade to the latest OpenAI SDK and adjust code for ComputerTool GA and any renamed preview classes.
- 02.
Gate rollout via feature flags and compare 5.4 vs current models on accuracy, latency, and token spend.
Fresh architecture paradigms...
- 01.
Design agents around Tool Search and native computer use with clear guardrails, sandboxing, and human-in-the-loop checkpoints.
- 02.
Exploit 1M-token context for planning and verification, but enforce budgets and compaction from day one.
