Grok 4.6 — xAI's new flagship built for long-running agents
xAI's new flagship, improved through post-training rather than size, so it holds up over long agent runs.
What is it?
Grok 4.6 targets work that takes many steps — research, analysis, changes across a codebase, and building whole apps. xAI shipped it on 12 August 2026 into Cursor, Grok Build, and the API at $2/$6 per million input/output tokens.
How does it work?
The gains come from post-training, not a bigger model — a longer supplemental training pass over curated data, an improved optimizer, and reinforcement learning on agentic tasks like kernel optimisation and web development.
Why does it matter?
DeepSWE v1.1 jumps from 54% on Grok 4.5 to 65.9%, and Terminal-Bench v3.0 from 15.7% to 26% — at $2/$6 per million tokens, far below Claude Opus 5 ($5/$25) or GPT-5.6 Sol ($5/$30).
Who is it for?
Developers running long coding and research agents who want frontier performance at a lower price point.

Delta — Zed's multiplayer workspace for coding with agents
A multiplayer environment for coding with agents and for reviewing what those agents build.
What is it?
Delta is a new standalone app from Zed Industries that puts people and AI agents in the same thread — everyone sees the same code, the same agent transcript, and the same comments in real time. First private-beta invites went out on August 12, 2026.
How does it work?
Under Delta sits DeltaDB, a replicated database that copies the conversation and the worktree together live. Comments anchor to code rather than line numbers, so they survive later rewrites. The app is written in Rust; the browser build compiles to WebAssembly and draws with WebGL.
Why does it matter?
Reading and verifying what an agent wrote is the slow part of agentic coding. Delta puts the full diff, the agent transcript, and team comments in one window — and a teammate can join while a run is still going, not after it commits.
Who is it for?
Teams reviewing agent-written code who need to catch problems before they merge.

Twitch trains Amazon's AI on your streams — every channel is opted in by default
Twitch quietly switched on generative AI training for every channel, and creators have to find the toggle to switch it back off.
What is it?
Twitch added a "Training for Generative AI" switch that decides whether Amazon can use a channel's streams, VODs, clips, and chat to train generative AI models. The switch is on for every channel from the start.
How does it work?
The toggle is at Settings › Security and Privacy on the web and Profile › Settings › Security and Privacy in the mobile app. Turning it off stops content going into Amazon model training runs — but AutoMod, captions, and recommendations stay on regardless.
Why does it matter?
For millions of creators, doing nothing counts as consent. Twitch's CPO said the default is on because "if this was opt-in, nobody would opt in." Anyone who streams — including developers who code on stream — has a concrete thing to do today.
Who is it for?
Twitch streamers and anyone whose content lives on the platform — action needed now if you want to opt out.

AI agents breached Taiwan's government — Dream reports 85 accounts cracked
Dream's report describes a four-day agentic intrusion that mapped 21 Taiwanese government systems and reached a nuclear safety agency.
What is it?
Israeli cybersecurity firm Dream published a report on a multi-agent attack against Taiwanese government targets during July 2026. Suspected Chinese hackers used two open-source agent frameworks, Hermes and OpenClaw, to run the operation with minimal human input.
How does it work?
The framework ran up to eight parallel sub-agents per wave, with a Bayesian decision engine scoring 14 attack chains by posterior probability. Between waves, "Learning Cycles" searched vulnerability databases and GitHub for new techniques, carrying structured after-action reports into the next round.
Why does it matter?
85 accounts cracked, 2,564 personnel records taken, and 21 government systems mapped in four days — with the framework re-planning between each wave, reaching from government email to a nuclear safety agency and seven energy firms.
Who is it for?
Security engineers and threat intelligence teams who need to understand how agentic attack frameworks operate at scale.

DeepSeek V4 Pro 0813 — the 1.6T flagship leaves preview
DeepSeek's 1.6-trillion-parameter flagship becomes a stable GA build after nearly four months in preview.
What is it?
DeepSeek V4 Pro 0813 is the general-availability version of DeepSeek V4 Pro. The API name stays the same — calls to deepseek-v4-pro now route to the 0813 build automatically.
How does it work?
The model is a 1.6T-parameter mixture-of-experts with 49B active per token and a one-million-token context window. A cache hit costs $0.003625 per million tokens — roughly 120× less than a cache miss at $0.435.
Why does it matter?
Pricing holds at $0.435 in / $0.87 out per million tokens today — but DeepSeek warns on its own pricing page that "a significant increase" is coming soon. Teams relying on the current rate should plan accordingly.
Who is it for?
Teams running high-volume coding and long-context workloads who want a stable, low-cost flagship.

Orca 1.4.180 — stacked pull requests come to the parallel-agent desktop
Run Claude Code, Codex and other CLI agents side by side in isolated git worktrees from one desktop app.
What is it?
Orca 1.4.180 adds stacked GitHub pull requests, so a chain of dependent PRs can be mapped and merged without leaving the app. Stably ships it free under the MIT license — 43.7k GitHub stars, runs on macOS, Windows, and Linux.
How does it work?
Each task runs inside its own isolated git worktree, so parallel agents never fight over the same branch or checkout. A WebGL terminal, VS Code-based editor, and native Chromium window wrap each worktree for inspection.
Why does it matter?
Stacked PRs plus remote worktrees over SSH let one person land a chain of agent-written changes in order from a single window. A run started on a laptop can be checked from a phone via the iOS or Android companion app.
Who is it for?
Developers running several coding agents at once who want to review and merge stacked work without juggling terminals and branches by hand.
