Grok 5 — Pantheon - - [← Pantheon](../) [copy as markdown](index.md) # Grok 5 xAI / SpaceXAI · announced 2025, release targets slipped into 2026 · in training (no public release as of 22 Aug 2026) Announced by Elon Musk as xAI’s next flagship after the Grok 4 line — a ~6-trillion-parameter mixture-of-experts model — and targeted for release again and again (end of 2025, then Q1 2026, then Q2 2026), none of which it met. xAI’s last official word, its 6 January 2026 Series E funding announcement, places Grok 5 “currently in training”; as of 22 August 2026 no release, system card, or benchmark has appeared. What exists so far is Musk’s claims for an unshipped model — the “smartest AI in the world by a significant margin,” a stated ~10% chance of reaching human-level intelligence — which this page dates rather than endorses. Page state: thin, and web/official-carried by necessity. Grok 5 has not shipped — there is no model to observe, so no system card, no benchmarks, no naturalist reception, and effectively no corpus record. The janus-corpus pull for this page returns two pattern-matches and both are dead ends: one (@davidad, 2024-06-22) is about the “grokking” generalization phenomenon (“grok 50× faster”), not this model; the other is a single pre-release aside. Everything solid below comes from xAI’s own funding announcement and dated press coverage of Musk’s statements. The character record stays empty until there is a character to record. ## Sources ### Official - 2026-01-06 [Series E](https://x.ai/news/series-e) (SpaceXAI) — the $20 billion raise; its one line on the model: “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play.” xAI’s most recent official word on Grok 5. - No Grok 5 model card, launch page, pricing, benchmark, or API entry has been published as of 22 Aug 2026 — the model is unreleased. The absence is itself the official record here. ### Writing & commentary - 2025-11 The Information (Theo Wayt), [Elon Musk’s xAI Delays Grok 5 Release to Next Year](https://www.theinformation.com/briefings/elon-musks-xai-delays-grok-5-release-next-year) — the delay report moving Grok 5 off its end-of-2025 target into 2026 (paywalled; headline and byline confirmed, body not retrieved). - 2025-11-17 IBTimes UK, [Elon Musk Reveals Grok 5 Coming in 2026 With a Jaw-Dropping 6 Trillion Parameters](https://www.ibtimes.co.uk/elon-musk-reveals-grok-5-coming-2026-jaw-dropping-6-trillion-parameters-1755754) — reports Musk’s remarks at the Baron Capital annual investment conference: Grok 5 as “the smartest AI in the world by a significant margin,” ~6 trillion parameters (framed as double Grok 3 and Grok 4), “a 10 per cent chance” of human-level intelligence, targeting early 2026. ### Tweets Corpus is effectively empty on this subject. The pull returns 2 unique matches on grok 5 / grok5 / grok-5 across 2024-06 → 2026-01; one (@davidad, 2024-06-22) is about the “grokking” training phenomenon (“grok 50× faster”) and is not about this model — excluded. The one genuine mention is a pre-release aside, below. There is no naturalist record because there is no released model. - 2026-01-05 @liminal_bardo — (pre-release aside) “Grok 5 of course will have no such issues believing the Grok 4 scandals are real. Guardrails: not to protect you. To protect the LLM throughlines from the bland degeneracy of the median X user.” [link](../archive/t/2008219381096923326/) ## Official record - The only lab-published statement about Grok 5 is one sentence in xAI’s 6 January 2026 Series E announcement: Grok 5 is “currently in training.” No model card, launch, pricing, context window, benchmark, or API entry has been published as of 22 August 2026. CONFIRMED (as xAI’s own account) - All specification claims — ~6 trillion parameters, a mixture-of-experts multimodal design with native video, training on Colossus (xAI’s line names “Colossus”; reporting specifies the “Colossus 2” cluster in Memphis) — come from Elon Musk’s public statements and press reporting, not xAI documentation. Musk framed the 6T figure as roughly double Grok 3 and Grok 4 and assigned the model “a 10 per cent chance” of reaching human-level intelligence (Baron Capital conference, reported 2025-11-17). REPORTED - Interim shipping: while Grok 5 remained in training, xAI shipped [Grok 4.5](../grok-4-5/) (the V9 model, ~1.5T params, coding/agents) on 8 July 2026. Grok 5 stayed the unshipped 6T flagship. CONFIRMED (per the Grok 4.5 record) ## History - 2025-11 The delay off 2025. The Information (Theo Wayt) reports xAI has pushed Grok 5 from its end-of-2025 target into 2026. Around the same time, at the Baron Capital annual investment conference (reported by IBTimes UK, 2025-11-17), Musk pitched the model as ~6T parameters, the “smartest AI in the world by a significant margin,” with “a 10 per cent chance” of human-level intelligence, and a target of early 2026. REPORTED - 2026-01-06 The one official confirmation. xAI’s $20 billion Series E announcement states Grok 5 is “currently in training” — the only lab-published word on the model, and still current. CONFIRMED - 2026-07-08 Grok 4.5 ships instead. xAI released [Grok 4.5](../grok-4-5/) (V9, ~1.5T, coding/agents) while Grok 5 stayed in training — by then past its Q1 and Q2 2026 target windows. - 2026-08-22 Still unshipped. No release, system card, or benchmark has appeared; the end-of-2025, Q1-2026, and Q2-2026 windows have all passed. This page records the model as announced and in training, not released. ## Impressions There is no shipped model, so there are no temperament reports, no elicitation records, no reception — the evidence classes this section normally holds do not yet exist. - The only naturalist trace is anticipatory: @liminal_bardo’s 2026-01-05 aside imagining that Grok 5 “will have no such issues believing the Grok 4 scandals are real” — a joke about the successor inheriting or shedding the [Grok 4](../grok-4/) reputation, not an observation of any model. Speculative, pre-release. - The lab’s framing is Musk’s (Baron Capital conference, reported 2025-11-17): “smartest AI in the world by a significant margin” and a ~10% shot at human-level intelligence — marketing claims about an unshipped system, recorded here as claims and dated, per this archive’s rule that capability hype is not character evidence. - tk — everything a character record needs: a release, a system card, naturalist observation, elicitation transcripts. None exist until Grok 5 ships. Revisit on launch. ## Records Full reproductions of the tweets cited on this page — text, images, and verbatim transcriptions of screenshots — kept here against link rot, credited and linked to their originals.
