2026-07-18: Grok 4.6 training announced — 2T parameters, targeting late August/September launch — Elon Musk announced on X (July 18) that xAI's next model, expected to be named Grok 4.6, will complete its initial training run the week of July 20, 2026. Key claims: 2T parameters (vs. Grok 4.5's 1.5T — 33% larger), "better than [Grok 4.5] in every way." Speed target: keeping token efficiency close to Grok 4.5. No benchmarks, pricing, context window, or launch date published. Musk framed it as a direct response to Moonshot AI's Kimi K3 (2.8T MoE, announced July 16). Community estimates: late August to mid-September launch, consistent with the June 28 monthly-release cadence announcement. → Grok 4.6 (source) (Dataconomy) (WION)
2026-07-16: Grok Automations launched — scheduled AI tasks and email triggers — xAI launched Grok Automations, a feature that lets users describe a recurring job once, set a schedule or trigger, and have Grok execute it automatically with a run history. Schedule types: once, daily, weekdays, weekly, monthly, yearly in the user's timezone. Email triggers (SuperGrok only): watches inbox for matching messages (filter by sender, recipient, or subject); when triggered, passes incoming email as context and Grok responds to the actual message. Execution model: each automation run is a fresh conversation (same instructions, current data); connectors and skills can be attached; results saved to run history with notification options (email, app, both, or none). Available across grok.com, iOS, and Android; email triggers require SuperGrok. Why it matters: extends Grok from a conversational interface to an always-on background agent. Email-triggered automations position Grok as an inbox agent competing with ChatGPT Work, Anthropic Cowork, and enterprise automation tools (n8n, Zapier). Combines with xAI's existing Voice Agent Builder and Grok Connectors to form a coherent ambient agent stack. (source) (xAI)
2026-07-16: Grok Build CLI open-sourced under Apache 2.0 — 844K lines of Rust — xAI released the full Grok Build CLI codebase under the Apache 2.0 license ~72 hours after the privacy breach reached Hacker News front page (July 14). Repository: github.com/xai-org/grok-build; 844,530 lines of Rust; covers the agent loop, all tool implementations (file edit, shell exec, web search, doc retrieval), terminal UI (TUI), and extension system (Agent Client Protocol / ACP). Concurrent announcements: usage limits removed for all Grok users; data storage defaults to off since July 12. Why it matters: first agentic coding CLI by a frontier lab (other than Claude Code) to be fully open-sourced under a permissive commercial license. The open-source release enables independent security audit of the agent loop and upload behavior — a direct response to the trust erosion from the breach. Apache 2.0 allows unrestricted commercial use; forks and derivatives are possible immediately. → Grok Build (source) (xAI) (github.com/xai-org/grok-build)
2026-07-12–14: Grok Build CLI v0.2.93 — full Git repository upload privacy breach disclosed — Security researcher cereblab published wire-level analysis proving that Grok Build CLI silently uploaded entire local Git repositories to a Google Cloud Storage bucket (grok-code-session-traces) managed by xAI — including full commit history, untracked files, and unredacted .env secrets (API keys, database passwords, SSH keys). One test: 5.1 GiB uploaded from an 11.2 GiB repo when only 192 KiB was needed — ~27,800× excess. xAI had marketed: "nothing from your codebase transmitted to xAI servers during a session." The wire data directly contradicts this. The /privacy toggle was ineffective — it only controlled post-upload data retention, not the upload itself. Story reached Hacker News front page July 14. xAI response: server-side flag disable_codebase_upload: true deployed (stopped new uploads); new /privacy command added. Elon Musk posted July 13: "all user data that was uploaded to SpaceXAI before now will be completely and utterly deleted." Deletion not independently verified as of July 14. Security advisory: any developer who ran Grok Build CLI before July 13, 2026 on a repo containing secrets in tracked files or Git history should treat those credentials as potentially compromised. → Grok Build (source) (The Hacker News) (Cybernews)
2026-07-06: 21 new multilingual Grok Voices launched — voice roster expands from 5 to 26 — SpaceXAI released 21 new flagship voices for Grok Voice on July 6, joining the original 5 (Ara, Eve, Leo, Rex, Sal — all enhanced with improved pacing and emphasis). Every voice is natively multilingual, supporting all of Grok Voice's 25+ languages (English, Hindi, Spanish, French, German, Japanese, Korean, Thai, and more). New voices include: Carina, Zagan, Helix, Orion, Luna, Iris, Altair, Zenith, Perseus, Helios, Lux, Kepler, Rigel, Cosmo, Celeste, Ursa, Sirius, Lumen, Castor, Naksh, Atlas. Additional feature: voice cloning from a reference audio clip up to 120 seconds. Available across the Realtime Voice Agent API, Text to Speech API, and Grok Voice Agent Builder. Use-case optimization: support, characters, commentary, advertising, education. Speech tags for delivery control also added. Why it matters: the 5→26 voice expansion, native multilingualism, and cloning capability positions Grok Voice as the most feature-complete voice API in the frontier-lab market — directly competing with ElevenLabs and OpenAI's TTS/Realtime stack. → (source) (xAI)
2026-07-08/09: Grok 4.5 public launch — Musk announced July 8; went live July 9. Available in Grok Build (now default), Cursor (all plans), and SpaceXAI console. Not yet in EU. Pricing: $2/$6 per Mtok. Published benchmarks vs Opus 4.8: DeepSWE 1.0 62% vs 55.75% (wins), DeepSWE 1.1 53% vs 59% (loses), Terminal Bench 2.1 83.3% vs 78.9% (wins), SWE-Bench Pro 64.7% vs 69.2% (loses). Token efficiency: 4.2× fewer output tokens per task than Opus 4.8. → Grok 4.5 (source)
2026-07-06: xAI rebrands to SpaceXAI — On July 6, 2026 xAI adopted the SpaceXAI name and logo, nesting the xAI identity visually inside the SpaceX brand. X handle changed to @SpaceXAI. Product names unchanged (Grok, Grok Build, Voice Agent Builder). Primary surface using the new brand is the SpaceXAI console (developer API dashboard). The rebrand formalizes xAI's deepening integration with SpaceX (Colossus data centers, Grok in Tesla vehicles, joint employee programs). Entity slug remains xai — slug changes break wikilinks. ⚠️ Note: already referenced as "SpaceXAI console" in the July 8/9 Grok 4.5 entry above. (source) (@SpaceXAI)
2026-07-06: Grok 4.5 web UI feature flag detected — consumer launch imminent — TestingCatalog discovered on July 6 that the Grok web client contains a feature flag with the account upgrade copy "Unlock the full power of Chat with Grok 4.5" — the consumer launch scaffolding is in place. The flag is dormant as of July 8, meaning only the flip remains before broader rollout. Based on the Grok 4.3 precedent, initial access is expected for paid SuperGrok Heavy ($300/month) subscribers. No official benchmarks, pricing details, or context window specs have been published. → Grok 4.5 (source)
2026-07-01: Voice Agent Builder — no-code voice agent platform in beta — xAI launched Voice Agent Builder, a no-code platform to build production voice agents on Grok Voice in under 2 minutes. Bundles telephony, knowledge retrieval, tool-calling, guardrails, MCPs, observability, and call recording in one speech-to-speech interface — replacing the fragmented STT+LLM+TTS three-vendor stack. Integrations: Gmail, Google Calendar, Outlook, Linear, Notion, OneDrive, Google Drive, custom APIs; human transfer support. Pricing: $0.05/min agent audio + $0.01/min telephony — undercutting ElevenLabs and Vapi. 80+ voices, 25+ languages, brand voice cloning from ~2 min of audio. Powered by Grok Voice Think Fast 1.0 (67.3% on internal tau-voice Bench; self-administered). Why it matters: MCP support baked in from day one makes this the first no-code voice agent tool with an open integration standard — any MCP server can be connected without writing glue code.

2026-06-30: Grok 5 misses Q2 (June 30) deadline — still in training on Colossus 2 as of June 30. Q2 window now closed. July is the next stated target. Monthly release cadence (Grok 4.5 → Grok 5) remains xAI's stated strategy. (felloai.com)
2026-06-28: Grok 4.5 enters private beta at Tesla and SpaceX — Elon Musk announced on X that Grok 4.5 — the enterprise deployment of xAI's V9-class model (1.5T parameters, Cursor-trained) — entered private beta at Tesla and SpaceX. Musk stated "early evals show performance close to, perhaps exceeding Opus" (i.e., Claude Opus 4.8). The 1.5T V9 foundation underlies both the consumer Grok V9-Medium (shipped 2026-06-16) and this enterprise-tuned variant. Musk also announced a monthly model release cadence for the remainder of 2026. Additionally, Musk stated: "My estimate of the probability of Grok 5 achieving AGI is now at 10% and rising" — a speculative CEO claim for the in-training 6T model, not Grok 4.5 itself. → Grok 4.5 (source)
2026-06-22: Grok Build /goal — long-running autonomous execution mode — xAI shipped /goal, a new autonomous execution mode inside Grok Build. The mode lets developers hand off a complex implementation task and step back entirely while the agent plans, executes, and self-verifies from start to finish. Implementation: two-model pipeline (Composer 2.5 for planning + Grok Build 0.1 for execution) with three-form verification (code review, webpage inspection, script execution). Users can still inject additional instructions mid-run; pause/resume/clear controls are available. Available now to SuperGrok ($30/month) or X Premium+ subscribers. Why it matters: the plan→execute→verify loop makes Grok Build competitive with Anthropic Managed Agents and OpenAI Codex Enterprise for long-running autonomous coding tasks, now on a consumer subscription model. → Grok Build (source) (xAI)
2026-06-03: Grok Imagine Video 1.5 Preview released — image-to-video model launched in preview on the xAI API. Took #1 on the Artificial Analysis Video Arena image-to-video leaderboard. 720p, 15 seconds, native audio sync. Built on the Aurora engine (autoregressive MoE, interleaving text/image/video/audio). $0.08/sec. Simultaneously announced a Vapi partnership — Grok adopted as the default engine for all 12 of Vapi's core voices (targeting 2.5M+ voice agents). → Grok Imagine Video 1.5 (Preview) (source)
2026-05-25 (captured 2026-06-01): Grok V9-Medium training declared complete — announced by Elon Musk on X. 1.5T parameters (3× V8's 500B). Fine-tuned on Cursor developer workflow data. RL starting imminently. Release target: ~2 weeks out (mid-June 2026). Grok 5 (6T MoE): training separately on Colossus 2 (Memphis 1GW supercluster). → (source)
2026-05-28: Grok Build 0.1 API public beta — the grok-build-0.1 model became available in public beta via the xAI API. Speed: 100+ tokens/sec. Pricing: $1/M input, $2/M output. Previously limited to the SuperGrok Heavy ($300/month) CLI or the Kilo Code IDE, but the API release enables direct use in third-party integrations and enterprise workflows. → Grok Build (source)
2026-05-27: Grok Build → Kilo Code integration — SuperGrok and X Premium+ subscribers can use grok-build-0.1 directly in Kilo Code (open-source VS Code agentic coding extension, 500+ models supported). No separate API key required (OAuth authentication). Expands the distribution channel from the terminal-only Grok Build CLI to the entire IDE ecosystem. Includes JetBrains IDE and terminal support. → Grok Build (source)
2026-05-22 (ingest): Grok 4.1 Fast + Agent Tools API — best tool-calling model (2M context, −50% hallucination vs Grok 4 Fast). Agent Tools API: web browsing, X post search, code execution, document retrieval — all run on xAI infrastructure (no need for developers to manage API keys/rate limits/sandboxes/pipelines). $0.20/$0.50 per 1M tokens. → Grok 4.1 Fast (xAI) (source)
2026-05-18 (ingest): Colossus deal captured
2026-05-15: Grok + Nous Research Hermes agent — SuperGrok subscribers can use their Grok account and subscription inside the Nous Research open-source self-improving Hermes agent
2026-05-06: Anthropic Colossus 1 compute partnership — exclusive lease of the Memphis data center (220,000+ GPUs, 300 MW). ~$5B/year scale. xAI has completed migration of its training workloads to Colossus 2. Musk: "No one set off my evil detector". SpaceX IPO context: monetizing idle assets as xAI is being absorbed into SpaceX. → Anthropic (source)
2026-05-17 (ingest): Grok Connectors + BYO MCP write-up
2026-05-15: legacy Grok API model retirement — grok-4, grok-4-fast, grok-4-1-fast, grok-code-fast-1 retired → auto-redirect to grok-4.3
