Grok

Grok Imagine Video 1.5 moved from arena ranking to usable APIs, with xAI docs live and third-party access on fal and Venice. That matters because developers can now script against the model through standard providers, though early #1 arena claims are already being challenged by side-by-side testers.

Grok Imagine Video 1.5 Preview took the top 720p Image-to-Video Arena slot with a reported 52-point gain over the previous Grok video model. xAI docs and shared console pricing put the model at $0.08 for 480p and $0.14 for 720p, giving developers a concrete new API option for video generation.

Nous Research shipped Hermes Agent v0.14.0 with Grok subscription access, Codex as an OpenAI runtime, LINE, native video generation, and a Windows beta. This matters because Hermes is moving beyond point integrations into a broader agent runtime with new access paths and deployment surfaces.

Nous Research expanded Hermes Agent so X Premium+ and SuperGrok logins can unlock Grok 4.3, X Search, and media tools without separate keys. Bookmarks and full X API access still sit outside the OAuth path.

Nous Research added SuperGrok support to Hermes Agent, letting users plug a Grok subscription directly into the framework. It broadens Hermes beyond OpenAI runtimes and local setups into another mainstream agent model path.

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.
