2026 Shift: Integrating GPT-5.4 in OpenClaw Agent Workflows [Update]

Integrating GPT-5.4: My 1.05M Context Agent Workflow

TL;DR: OpenAI just dropped GPT-5.4 with native Computer Use and a 1.05M token context window. If you're building agents, this changes how you handle repo-scale tasks. Pricing is slashed to $2.50/1M input.

Real-World Test: Loading a Full Repo

With 1M context, you no longer need to rely purely on RAG for codebase orientation. You can feed the core logic directly:

{
  "model": "gpt-5.4",
  "messages": [
    {"role": "user", "content": "Analyze this entire src/ directory and refactor the auth logic..."}
  ]
}

FAQ

Q: How is it so cheap?
A: Incremental memory technology allows the model to cache context much more effectively, reducing redundant compute.
