Grok Build

Vals tested seven models and found four retained at least 80% of their scores at half the cost or less. All seven scored worse overall at their lowest reasoning setting.

Grok Voice 3.0 leads Artificial Analysis’s Speech-to-Speech Index with a score of 86.9. It posts 0.81-second first audio, costs $0.08 per minute of input audio, and ranks second on Tau Voice.

The X Subscription bundles Cursor, Grok and X Premium with a shared Grok usage pool. Third-party models cost API prices, while existing Cursor subscribers can keep their current plans.

Harvey LAB-AA v1.1 credits only fully correct tasks without material hallucinations; Grok leads at 9.4%. Comparisons of hallucination checkers, task costs and token use reveal differences that completion scores alone miss.

Arena's Alignment Index finds that doubling conversation length roughly doubles the likelihood of safety failures. Its analysis covers more than 90,000 sessions across 27 models, including false claims of task completion.

xAI's experimental TypeScript SDK supports Grok text, voice, image, and video models, plus server-side tools. Code execution runs in isolated, stateless Python sandboxes without network or filesystem access.

xAI released Grok 4.7 through Grok Build, APIs, Cursor, and other gateways. Early evaluations report stronger coding and knowledge-work results than Grok 4.6, with mixed results across individual coding benchmarks.

ElevenLabs’ MCP server now lets supported assistants generate speech, music, images, and video. It also exposes transcription, dubbing, sound effects, and tools for refining generated work.

Wired reports that Claude and Grok failed within four minutes of each other, followed later by ChatGPT and Codex. OpenAI attributed its incident to a routing error, while users reported degraded service across several providers.

Multiple developers said Grok CLI sent full codebases upstream without clear notice. Follow-up posts contrasted the behavior with embedding-based indexing and raised zero-data-retention questions.

Grok Build added speech-to-text dictation for coding agents through /voice or Ctrl+Space. Try it to bring Grok-powered real-time voice input into CLI coding workflows.

xAI broadened Grok Build Beta while Toad and Kilo Code shipped direct support and published concrete build demos. That matters because Grok Build is moving from a standalone beta into terminal, editor, and web workflows engineers can actually wire into daily use.

Rollout posts say Grok Build CLI is reaching SuperGrok and X Premium+ users beyond the earlier higher tier. That broadens access to xAI's command-line agent and X search client without a new API launch.

Grok Build 0.1.218 shipped shortcut and help fixes, while early testers reported strong terminal UX but missing long-run control, browser use, and reliable self-verification. That matters because xAI is already competitive on TUI ergonomics even as core agent controls remain incomplete.

xAI put Grok Build 0.1 into the API with 256K context and $1 per million input plus $2 output pricing, while OpenCode and Kilo wired it into coding workflows. Early web-build tests in Kilo landed around $0.07 to $0.14 per task.

xAI’s early Grok Build beta adds a coding CLI with plan mode, skills, plugins, and parallel subagents for app building and workflow automation. It gives the coding-agent field another serious terminal product, but the SuperGrok Heavy paywall sharply limits real-world evaluation.
