xAI's news index documents rapid post-launch distribution of Grok 4.6 across major developer and enterprise platforms in August 2026. The model became available on GitHub Copilot on August 19, on Amazon Bedrock on August 19, on the Gemini Enterprise Agent Platform on August 21, and on Microsoft Foundry on August 26, wi Adjacent product launches tracked on the same page include Grok Build reaching every plan on web and mobile (August 19), Grok Bot gaining tighter X integration with account linking and free X API credits for paid users (August 29), and an Aug 12 release framing Grok 4.6 as building on Grok 4.5 with emphasis on long-run

IntuitionLabs profiles Grok 4.6 as a coding- and agent-focused frontier model released by xAI (operating as SpaceXAI) on August 12, 2026, with a 500,000-token context window, configurable reasoning effort, native function calling, and structured outputs. The piece draws on xAI's official release notes for pricing, conf The analysis echoes Artificial Analysis's GDPval-AA v2 Elo of 1753 for Grok 4.6, placing it second only to Claude Opus 5 on agentic real-world work and roughly half the turn count of Claude Opus 5 on long-horizon tasks. It positions Grok 4.6 as price-competitive with Claude Sonnet 5's input cost and undercutting Claude

Layer3 Labs' guide, reviewed September 9, 2026, summarizes xAI's August 12, 2026 launch of Grok 4.6 as a model built for complex, long-running agentic and visual tasks, sustaining multi-step work across research, software development, and major project organization. xAI highlights improved multi-step reasoning, stronge The article tabulates xAI's official benchmark scores: AA Intelligence Index 61 (matching GPT-5.6 Sol), GDPVal-AA v2 1753 (above Grok 4.5 and GPT-5.6 Sol, close to Fable 5 Max at 1741), CursorBench v3.2 69.9% (above GPT-5.6 Sol's 67.2%, just below Fable 5 Max's 70.5%), DeepSWE v1.1 65.9% (up from Grok 4.5's 54%, below

A developer-oriented long-form analysis from AI-Driven Lab (note.com) covering the Grok 4.6 launch dated August 12, 2026 by SpaceXAI, reportedly rebranded from xAI. The article frames Grok 4.6 as targeting coding, long-running agents, and visual/interactive work, with a Cursor co-announcement referenced and reorganized The write-up compiles benchmark positioning, pricing surfaces, and availability channels for Grok 4.6, and provides historical context on the xAI to SpaceXAI corporate restructuring. The piece is auto-translated from Japanese with an explicit accuracy disclaimer, and is a third-party user-published summary rather than

xAI's official developer release notes confirm that Grok 4.6 launched on the xAI API on August 12, 2026 as a frontier model for coding, agentic tasks, and knowledge work. The model features a 500k context window, text and image inputs with text-only output, and no output token limit. Pricing is tiered: $2 per 1M input The release notes also document adjacent API updates: grok-imagine-image-2.0 now accepts an auto quality parameter (defaulting when omitted) and supports up to 5 reference images for editing, plus new 21:9 cinematic and 5:2 banner aspect ratios. Earlier entries detail grok-imagine-video-1.5 supporting text-to-video, im

Pragma-Code's enterprise review positions Grok 4.6 as an engine for autonomous agentic workflows, capable of remaining anchored across dozens of sequential file edits, test executions, and compiler feedback loops without drifting. The model achieves a record score of 1,753 points on GDPVal-AA v2 and 1,577 points on AA- The review details Grok 4.6's training approach, including SFT trajectory regeneration and agentic reinforcement learning, as drivers of its stress-test benchmark performance. A key capability highlighted is visual and interactive first-pass synthesis, where the model translates ambiguous product briefs into cohesive v

AWS announced that Amazon Bedrock now supports SpaceXAI Grok 4.6 with Cross-Region Inferencing (CRI). The page is hosted on aws.amazon.com under the "What's New" feed dated August 19, 2026, and directly names SpaceXAI Grok 4.6 as the supported model. This gives developers a managed, enterprise-grade distribution channe While the supplied excerpt is truncated by AWS's cookie consent UI, the announcement establishes Bedrock as an additional official access path beyond the xAI API and named partner channels. Cross-Region Inferencing on Bedrock typically distributes requests across multiple AWS regions to improve availability and through

A DEV Community post by an agent-building developer provides the most technically detailed secondary account of Grok 4.6's training recipe. xAI describes a longer supplemental training run than Grok 4.5, using curated model-generated data for reasoning and advanced technical concepts, high-quality engineering data, and xAI did not confirm a parameter count, leaving conflicting reports (1.5T V9 base shared with Grok 4.5 vs. a larger 2T model) unresolved. The behavioral claim that matters most for developers: on longer trajectories, Grok 4.6 shows more self-testing and verification, checking its own work before proceeding. For visual a

An independent benchmark breakdown published on Medium analyzing Grok 4.6 against GPT-5.6 Sol and Fable 5 Max using vendor-published numbers. The author reports Grok 4.6 wins 6 of 9 shared benchmarks versus GPT-5.6 Sol and 3 of 10 against Fable 5 Max, with both losses to Sol concentrated in agent and terminal work, not Pricing is restated at $2 per million input tokens and $6 per million output tokens, and availability is listed across Cursor, SpaceXAI Grok Build, the xAI API, OpenRouter, Vercel, and Cloudflare from August 12, 2026. The analysis is structured third-party evaluation, though the underlying benchmark figures are vendor-

Geotoolbox's explainer describes Grok 4.6 as xAI's frontier model released on August 12, 2026, built for long-running agents, coding, and knowledge work, landing about a month after Grok 4.5 as the current flagship. The post emphasizes that Grok 4.6 is not a bigger model than 4.5 — xAI describes a longer round of train The explainer walks through Grok 4.6's specs, benchmarks (with attention to losses), real cost beyond the headline price, comparisons against Grok 4.5, GPT-5.6, and Claude, and access channels including the xAI API, Cursor, and Grok Build. It frames the release as relevant to whether AI assistants can keep current with

Emergent.sh's benchmark deep-dive reports that Grok 4.6 scores 61 on the Artificial Analysis Intelligence Index, tying GPT-5.6 Sol and trailing Claude Opus 5 (63) and Claude Fable 5 (62). Despite being pitched as a model for agentic coding, the benchmarks show it wins the knowledge-work evaluations (GDPval-AA, AA-Brief Artificial Analysis independently measured a 65.7% non-hallucination rate for Grok 4.6 — a row xAI never published, which the review argues matters more for customer-facing work than any coding score. On efficiency, Grok 4.6 finished long agentic tasks in about 53 turns against Claude Opus 5's 103 turns, at $0.84 per t

According to AIToolsReview, Grok 4.6 launched on 12 August 2026, with independent testing from Artificial Analysis placing it at 61 on the Intelligence Index — exactly tying GPT-5.6 Sol, one point behind Claude Fable 5 and two behind Claude Opus 5, and representing a five-point jump over Grok 4.5 in just over a month. The same review notes that independent testing also found a meaningfully higher confident-fabrication rate than Grok 4.6's benchmark parity with GPT-5.6 Sol might suggest. It frames the release as SpaceXAI's fourth major Grok release since the company's February 2026 merger with SpaceX, and its second since the July re
