Reddit spots GPT-5.4 listing on LM Arena

Unverified reports on r/singularity claim a model labeled “GPT-5.4” appeared on LM Arena with text and image inputs, based on a screenshot and user discussion. No official OpenAI announcement is linked, so this remains leak-level signal rather than a confirmed release.

// ANALYSIS

This is useful early signal for model-watchers, but it is still rumor-grade until OpenAI publishes release notes.

–The announcement link is a Reddit thread, not a primary vendor post, so confidence should stay moderate.
–LM Arena sightings have historically surfaced model aliases before broader rollouts, but false positives also happen.
–“Text + image input” aligns with current multimodal expectations, yet doesn’t confirm capability level or availability.
–For developers, the actionable move is to monitor official model release notes and API docs before planning migrations.

Plannotator 0.19.24 adds Amp support and configurable storage

Plannotator 0.19.24 is a substantial release that expands the tool beyond Claude Code with native Amp support, adds a `PLANNOTATOR_DATA_DIR` override so users can move the default `~/.plannotator` data directory, introduces Auto Mode in the permission selector for newer Claude Code versions, and fixes a Pi approval crash after plan acceptance. The update folds multiple stacked PRs into one release and pushes the project further toward a multi-agent review layer rather than a single-agent hook utility.
