OpenClaw v2026.4.15: Claude Opus 4.7 Default & Gemini TTS
OpenClaw v2026.4.15 shipped on April 16, 2026 with two headline changes: Claude Opus 4.7 is now the default Anthropic model, and Gemini text-to-speech lands in the bundled Google plugin. Below is a complete breakdown of every change and what it means for AI-powered B2B sales workflows.
What's New in v2026.4.15
Claude Opus 4.7 Becomes the Default Model
The most impactful change in this release: OpenClaw now defaults all Anthropic model selections, opus aliases, and Claude CLI defaults to Claude Opus 4.7.
If your openclaw.json uses model: opus or any unversioned alias, it automatically resolves to Opus 4.7 — no config change required. Claude Opus 4.7 brings improved multi-step reasoning, better handling of long-context conversations, and stronger coherence across extended sales negotiation threads.
Why this matters for B2B SDR: Modern B2B sales conversations span 10–30+ turns — qualification, objection handling, pricing negotiations, and follow-ups. Opus 4.7's enhanced reasoning translates directly to more natural objection responses, tighter BANT qualification logic, and fewer hallucinated product details in complex quote threads.
Fact: AI-powered SDR agents using Claude Opus 4.7 handle 3× more concurrent leads than a single human SDR — without sacrificing conversation quality on complex deals.

Google Gemini Text-to-Speech Support
The bundled google plugin now includes full Gemini TTS integration:
- Voice selection — choose from Gemini's voice library
- WAV reply output — send voice notes directly in conversations
- PCM telephony output — use on IVR systems and phone channels
This opens a new channel for B2B sales teams using voice-heavy workflows — particularly relevant for WhatsApp sales automation where voice notes typically achieve higher engagement than text messages.
Fixes That Matter for SDR Deployments
Memory Context Budget Trimming
Default startup and skills prompt budgets are now smaller. memory_get excerpts are capped by default with explicit continuation metadata. In practice:
- Long sessions (30+ turns) consume less context window
- Memory continuity is preserved via structured follow-up reads
- Reduced cold-start API cost on each new conversation
For B2B export SDR pipelines handling hundreds of daily leads, this means lower per-conversation API cost without losing deal history.
Skill Sort Order Stabilized
available_skills entries are now sorted alphabetically after all sources merge. This prevents prompt-cache prefix changes when skills.load.extraDirs order shifts — a subtle but expensive bug that caused full cache misses on every deploy.
What Hasn't Changed
BlueBubbles attachment handling, CLI update internals, and Gateway tool security patches also ship in this release but don't affect typical B2B SDR deployments running WhatsApp/Telegram/email stacks.
Upgrade Instructions
npm install -g openclaw@latest
# or
npx openclaw@latest upgrade
After upgrading, verify your model alias resolves correctly:
openclaw model show # should display claude-opus-4.7 or equivalent
If you have a hardcoded model: claude-opus-4-5 and don't want the automatic upgrade, pin explicitly in openclaw.json.

Frequently Asked Questions
Q: Do I need to update my openclaw.json after upgrading to v2026.4.15?
No — if you use model: opus or any unversioned alias, it auto-resolves to Opus 4.7. Only update if you want to pin a specific version.
Q: Is Gemini TTS production-ready in v2026.4.15? Yes for standard voice output. The integration covers voice selection, WAV output, and PCM telephony. Advanced telephony configurations may require additional plugin setup.
Q: Will the memory budget trimming break my existing SDR workflows?
No. The trimming only affects default budgets. Memory continuity is preserved via continuation metadata. Existing memory_get behavior in skills is unchanged.
Q: Can I use Claude Opus 4.7 with PulseAgent? Yes — PulseAgent runs Claude Opus 4.7 by default. See pricing →
Q: What's the performance difference between Opus 4.5 and Opus 4.7 for SDR tasks? Opus 4.7 shows measurable improvement on multi-step reasoning tasks — complex BANT qualification chains, multi-objection handling, and long negotiation threads. For simple single-turn inquiries, the difference is minimal.
