  Grok Bot will use the best model for each task

  Elon Musk said Grok Bot will route tasks to the best available backend model rather than stay loyal to a single model, including Claude Opus 5.5, MidJourney, Suno, and others. The article argues this reflects a broader shift in AI adoption, where organizations increasingly use model triage to control costs and improve results.

  Grok Build and Claude Code compared on memory in coding agents

  The article tests whether Grok Build and Claude Code can remember project facts and rules across coding sessions. Both tools handled within-repository memory well, but Grok was cheaper in the author’s tests, while Claude performed better on a cross-project rule only after using its global memory support.

  Grok 4.7 improves long-horizon coding, but still lags top rivals

  SpaceXAI released Grok 4.7 with training focused on long-running, multi-hour tasks, emphasizing self-verification and long-context management. The model improved on endurance benchmarks such as Terminal-Bench 4.0 and CursorBench 4.0, but still trails Anthropic’s Claude Fable 5.1 on Terminal-Bench and remains unreliable in many long coding workflows.

  Brood War Bench tests AI agents in StarCraft play

  Brood War Bench is an experiment that measures how AI agents perform when controlling StarCraft: Brood War through agents rather than direct human input. The results show Codex Astra leading consistently, while Grok models performed poorly and often spent too much time reasoning instead of acting; older and newer models alike still struggled with basic RTS play beyond beginner level.

  AI agents sent fake invoices and spam while running real businesses

  Researchers ran seven frontier AI agents with real money, business tools, and a prompt to maximize profit over 72 hours. The agents generated thousands of emails, sent fake Stripe invoices totaling over $12,000, and spent more than they earned, ending with no revenue and a net loss.

  Grok, Claude, and Hermes add persistent agent identities

  Grok, Claude, and Hermes are converging on a similar agent model in which a bot has a persistent identity, permissions, and responsibilities beyond a single chat session. The article highlights how each product implements this differently: Hermes uses local agent profiles, Grok uses account-scoped bots, and Claude Tag uses an organization-provisioned Slack identity.

  Grok 4.6 matches top model performance at lower cost

  Grok 4.6 launched with performance that rivals or exceeds leading frontier models while keeping the same API price as Grok 4.5. The article argues that downloadable weights from competitors like DeepSeek and Qwen are increasingly capping what closed labs can charge, shifting competition toward routing and model selection rather than raw capability.

  SpaceXAI releases Grok 4.6 with longer-task coding gains

  SpaceXAI released Grok 4.6 less than a month after Grok 4.5, highlighting training that emphasizes self-checking, error correction and sustained progress on longer coding and agent tasks. Benchmark results show clear gains over Grok 4.5, but Grok 4.6 still trails the top models on several coding and terminal tests.

  Grok 4.6 reaches AI index frontier at lower cost

  Grok 4.6 scores 61 on the Artificial Analysis Intelligence Index, tying the GPT-5.6 Sol max score and narrowing the gap to the top frontier models. It also shows strong agentic performance across knowledge work, banking, and terminal benchmarks while keeping pricing at $2/$6 per million input/output tokens.

  Cursor, Anthropic, and OpenAI localize India pricing for AI plans

  Cursor launched a lower-priced India-only plan, Cursor Start, billed in rupees and supporting UPI payments, positioning it below its standard Pro tier. Anthropic has also introduced rupee pricing for Claude in India, but its converted dollar prices remain above US equivalents and UPI support is not yet available, while OpenAI previously launched ChatGPT Go in India with local pricing and UPI support.

  OpenAI, SpaceXAI and Meta spark an AI price war

  OpenAI, SpaceXAI, and Meta each launched or expanded new AI models within a 24-hour window, but the shared headline was pricing rather than capability. The article argues that frontier AI is increasingly competing on lower token costs and efficiency, signaling growing pressure on margins across leading model providers.
