If you blinked during the v2026.4.24 pre-release coverage, you may have missed something important: v2026.4.23 dropped on April 24 and it’s packed with features that deserve their own spotlight. This one fills the gap in our coverage between v4.22 and the v4.24 pre-release.

GPT-5.5 Integration

OpenAI’s GPT-5.5 (codenamed “Spud”) launched April 23 — and OpenClaw integrated it in v4.23 the following day via updated Pi packages. If you’re running OpenClaw and want to route requests through GPT-5.5, it’s now available through the standard provider configuration with no additional setup beyond updating to v4.23.

Initial benchmark data from Tom’s Guide puts Claude Opus 4.7 ahead in head-to-head logic and math tasks (7-0 across test categories), but GPT-5.5 brings OpenAI’s agentic reasoning approach and strong code generation to the OpenClaw provider catalog. For users with existing OpenAI API relationships, this is a meaningful addition.

The typical configuration update in ~/.openclaw/config.yaml:

models:
  default: claude-sonnet-4-6
  available:
    - openai/gpt-5-5
    - anthropic/claude-opus-4-7

Native Image Generation via Codex OAuth — No API Key Required

This is the headline feature for many users: native image generation and editing using gpt-image-2, integrated through Codex OAuth. The key implication is that you don’t need a separate OpenAI API key to use it — if you have a Codex subscription, the OAuth path handles authentication.

This dramatically lowers the friction for image generation in OpenClaw workflows. Previously, you needed to configure a dedicated API key with image generation permissions. Now, Codex OAuth handles that transparently.

The integration supports both generation and editing modes, using gpt-image-2 as the underlying model. Quality is strong for product mockups, diagram visualization, and content illustration use cases.

Practical note: gpt-image-2 via Codex OAuth operates within Codex’s usage tiers, so heavy generation workloads may hit rate limits faster than direct API access. For production pipelines with high image generation volume, a direct API key is still worth configuring.

Forked-Context Subagents

The third major feature in v4.23 is forked-context subagents — the ability for child agents to inherit parent context transcripts. This is a significant capability upgrade for complex agentic pipelines.

Previously, spawning a subagent meant the child started with a fresh context. If you needed the child to know what happened in the parent’s conversation, you had to manually pass that context. Forked-context subagents handle this automatically — the child can be initialized with a snapshot of the parent’s conversation history.

This has several practical applications:

  • Debugging pipelines: Spawn an investigative subagent that knows the full history of what led to a failure
  • Parallel task execution: Fork multiple specialized agents from the same conversation state without manually serializing context
  • Agent handoffs: Pass work from one agent to another with full fidelity on what’s been done

The feature requires explicit opt-in in subagent spawn configuration — it doesn’t fork context by default, which prevents accidental context leakage in shared environments.

What’s In v4.24 (For Context)

v2026.4.24 (pre-release) added Google Meet plugin, expanded the DeepSeek V4 model catalog, and improved voice loop reliability. v4.23’s features are distinct and already stable — this isn’t a pre-release. If you want production-ready GPT-5.5 support, Codex OAuth image generation, or forked-context subagents, v4.23 is the version to be on.
