SpaceXAI's Grok 4.7 added to Amazon Bedrock

SpaceXAI announced Grok 4.7 is available on Amazon Bedrock with features aimed at long-horizon agent workloads: a 500K-token context window, tool calling, configurable reasoning-effort levels (low/medium/high/xhigh), and support for Chat Completions/Responses and the Bedrock Converse API. In SpaceXAI's tests of a tool-calling agent on three search-style tasks, the agent answered 67 of 72 runs correctly (18/18 at xhigh; 15/18 at low), illustrating a tunable trade-off between correctness and token use; Bedrock access uses cross-Region inference profiles and requires specific IAM permissions.

AI-powered ARTEX used in likely single-attacker breach of multiple South Korean banks

CrowdStrike reports a suspected Chinese-speaking attacker breached multiple South Korean financial institutions between late September and early October 2026, stealing large volumes of customer data (Shinhan Bank reportedly lost over 25,000 records, per Khan). Researchers say the attacker used ARTEX—an open-source AI automated-penetration-testing tool leveraging DeepSeek v4.1-flash, GLM-5.3, and Grok 4.6—and left Claude Code session logs that indicate attempts to market stolen data.

xAI’s Grok 4.7 becomes available on Amazon Bedrock

xAI has made Grok 4.7 available via Amazon Bedrock (served through the bedrock-runtime endpoint with cross-Region inference profiles). The model offers a 500K-token context window, four configurable reasoning-effort levels (low/medium/high/xhigh), improved long-horizon self-verification for coding and knowledge work, new safeguards, and support for Responses, Chat Completions, InvokeModel and Converse APIs.

xAI’s Grok 4.6 is now available in Amazon Bedrock

xAI says Grok 4.6, a model with a 500K-token context window and four configurable reasoning levels, launched on Amazon Bedrock on August 18, 2026; it is served on both bedrock-mantle and bedrock-runtime and supports the Converse API as well as Chat Completions and Responses. xAI reports Grok 4.6 was trained with supplemental model-generated data and agentic reinforcement-learning tasks, and that it shows improved self-checking, first-pass visual/interactive outputs, and expanded safety testing; xAI published benchmark results including ones from Artificial Analysis.

SpaceXAI releases Grok 4.7 — faster, cheaper model for coding and knowledge work

SpaceXAI released Grok 4.7, a new base-model upgrade positioned as its most capable model for coding and knowledge work; it reportedly uses a larger base model, longer RL training focused on long-running tasks, and an entirely new safeguard stack. The company says Grok 4.7 matches the price and speed of Grok 4.6 while improving verification, longer-context handling, document/presentation generation, benchmark performance (CursorBench 4.0, GDPval, AA Briefcase), and safety metrics (LatchBio biosafety 62.4%, HackerBench v0.3 allowing 3.3% risky prompts); it is available in Cursor, Grok Build, the Grok API, third-party harnesses and cloud platforms, priced from $2 per million input tokens and $6 per million output tokens, with an optional faster (2x) variant at double the price.

SpaceXAI launches Grok 4.5, a model optimized for coding and agentic tasks

SpaceXAI says it has released Grok 4.5, its newest model trained alongside Cursor and optimized for coding, agentic workflows, and knowledge work. The company reports training across tens of thousands of NVIDIA GB300 GPUs, claims roughly 2× token efficiency versus leading models, 80 TPS serving speed, and priced the model at $2 per million input tokens and $6 per million output tokens; Grok 4.5 is available in Grok Build, Cursor, and via the SpaceXAI console with limited free usage offered.

LatchBio analysis finds Grok 4.6 best at refusing disguised biohazard tasks on BioSecBench

LatchBio published an independent analysis of Grok 4.6 using its BioSecBench suites. On BioSecBench-Refusal Grok 4.6 achieved the top results across harnesses (trial-weighted harmonic mean 62.1%), refusing 59.2% of red-team tasks while completing 64.8% of routine tasks (the only model >50% on both); on BioSecBench-Surveillance it averaged 53.5% success, behind Opus 5 and ahead of GPT-5.6 Sol. The report says evaluations used multiple agent harnesses and effort levels and includes additional routine biological capability results (e.g., SpatialBench, TxBench-PP) at benchmarks.bio.
