Same day Anthropic shipped Claude Opus 4.7, OpenClaw shipped the release that defaults to it. That kind of cadence is exactly what makes OpenClaw’s release velocity worth tracking — v2026.4.15 is out now, and it brings considerably more than a model bump.

Here’s what’s in this release and why each piece matters for practitioners.

Claude Opus 4.7 Is Now the Default

All Anthropic model selections, aliases, and Claude CLI defaults have been updated to point to Opus 4.7. If you’re running OpenClaw with Anthropic as your provider and haven’t pinned a specific model version, you’re already on the new default after upgrading.

The bundled image understanding also moves to Opus 4.7, which brings the higher-resolution vision capabilities into your agent pipelines automatically.

Gemini Text-to-Speech

This is the feature that will get the most attention from power users: the bundled Google plugin now includes Gemini TTS support with full voice selection, WAV reply output for standard use, and PCM telephony output for voice-over-IP integrations.

In practice, this means:

  • Voice selection: Choose from Gemini’s available TTS voices directly in your OpenClaw config
  • WAV output: Standard audio replies delivered as WAV files — works across Discord, Telegram, and other channel integrations
  • PCM telephony: Raw PCM stream for integration with phone systems and VoIP — relevant if you’re building call center agents or voice-enabled workflows

Setup requires a Google Cloud project with the Text-to-Speech API enabled and proper credentials in your OpenClaw config. A full setup guide is in the works.

Model Auth Status Card

The Control UI gets a new Model Auth Status Card on the Overview page — a real-time view of OAuth token health and provider rate-limit pressure across your configured models.

It surfaces attention callouts when tokens are expiring or have expired, backed by a models.authStatus gateway method that strips credentials (never exposes them in the UI), caches for 60 seconds, and aggregates across all providers.

If you’ve ever had a session fail mid-task because an OAuth token silently expired, this card exists to prevent that.

Cloud Storage for LanceDB Memory

The memory-lancedb extension now supports remote object storage, which means your durable vector memory indexes can live on S3, GCS, or Azure Blob Storage instead of local disk only.

This is significant for a few configurations:

  • Multi-instance deployments: Multiple OpenClaw nodes sharing the same memory index
  • Persistent memory on ephemeral hosts: Docker containers or auto-scaling instances that don’t have reliable local disk
  • Backup and portability: Memory indexes that survive server migrations

GitHub Copilot Embedding Provider

A new GitHub Copilot embedding provider for memory search is now available, with a dedicated Copilot embedding host helper that handles token refresh, remote override support, and payload validation safely.

Teams already using GitHub Copilot subscriptions get access to embeddings without adding a separate OpenAI or other embedding API key.

Lean Mode for Local Models

For users running OpenClaw on weaker local models (small LLMs, quantized models, lower-end hardware), a new experimental flag reduces the heavyweight default tool load:

agents:
  defaults:
    experimental:
      localModelLean: true

Setting localModelLean: true drops the browser, cron, and message tools from the default prompt — tools that contribute significant token overhead without being necessary for most local-model use cases. Normal cloud-model behavior is completely unaffected.

Other Notable Changes

  • Codex transport self-heal: Automatic recovery from Codex transport failures
  • Trimmed prompt budgets: Capped memory reads for long sessions to prevent context blowout
  • Safer tool/media handling: Additional validation on tool and media payloads
  • BlueBubbles image restoration: Fixed image handling on Node 22+ for BlueBubbles integration
  • Leaner package: Bundled plugin runtime dependencies localized to their owning extensions, keeping the core package slimmer

How to Upgrade

npm install -g openclaw@latest
# or
npx openclaw@latest

After upgrading, restart your gateway and verify the model defaults in your Control UI. If you’re enabling Gemini TTS or Lean Mode, those require explicit configuration additions — they’re opt-in.
