OpenClaw 2026.5.2 shipped Grok 4.3 as the default xAI chat model and a broad plumbing pass for plugins, session paths, messaging bridges, and voice features. The release matters because it trims startup stalls and cleans up common integration edges in self-hosted agent setups.
Provider and benchmark trackers listed Grok 4.3 with 1M context and lower token pricing, and OpenRouter and Venice exposed it through their APIs. The model undercuts Opus 4.7 and GPT-5.5 on price while independent evaluations show stronger legal and finance performance than general coding.
OpenClaw shipped a new release with a gateway-free local TUI, chat-time model registration, and xAI media tools. The update lowers setup friction and adds diagnostics plus trajectory bundles for debugging agent runs.
Grok added standalone speech-to-text and text-to-speech APIs with WebSocket streaming, word timestamps, diarization, and support for 25-plus languages. Developers building realtime audio apps can now call Grok Voice infrastructure directly instead of wiring it through the app UI.
