AIMiles runs the full reinforcement learning loop on Nvidia Rubin, using SGLang for rollout, Megatron for training, and one container image. On a single 4-GPU tray, Qwen3-30B-A3B's GSM8K reward rises from about 45% to about 95% over 50 rollouts, matching the GB300 curve. The post also reports DeepSeek-V4-Flash end-to-end rollout and training, and Qwen3.5-35B-A3B agentic RL with 64 concurrent mini-SWE-agent sandboxes on SWE-bench Verified, where reward holds near 0.6 and median response length falls about 30%.

AIRadixArk says Proximal is using Miles to train coding agents and calls it a flexible, scalable foundation for teams running their own training workloads. Proximal says its training framework is built on Miles, with runs on Modal's on-demand GPU clusters and serverless GPUs for inference. Its sandboxing infrastructure runs on Kubernetes and can handle millions of concurrent rollouts.

AIUnsloth now supports OS-level sandboxing on Linux via bwrap, on Mac via seatbelt, and on Windows via Microsoft's MXC. Per-tool-call latency is under 100ms across all three, and its software-style sandboxing with regex AST checks adds about 3ms. The Windows integration was built in collaboration with Microsoft.

AIOpenClaw released its v2026.9.9 patch, adding support for GPT-6.1 Sol in Codex and Claude Haiku 5.5. The update also improves recovery from failed updates, fixes missing iMessage replies, and resolves scheduled-job issues. The release credits 90 contributors.

AIAugment Code is selling select assets, including Cosmos, Auggie CLI, and the Code Context Engine, to Harness, and the product team is moving to Harness. The company says Harness's integrated platform delivers these capabilities to customers more effectively than building them independently. Harness describes itself as building the Autonomous SDLC Platform for shipping AI-written code across enterprises.

Why it matters: The announcement shows how a coding AI company is folding its products into a larger software delivery platform, a shift that shapes how enterprise teams will buy these tools.

AITessl's Code Review defines review standards as skills in the repository, called lenses, routed to files by a repo-owned profile file. Because these team-visible standards are portable, lessons from review can feed back into code generation and maintenance, not only the next review.

AILegalOn cut its estimated daily Codex costs by 65% while maintaining development speed. The company matched Astra, Sol, and Luna to tasks and managed budgets strategically.

AIDeveloper Brandon Thomas used Claude Opus 5.5 and Rust to build Artcraft, a free open-source suite with Photocraft, Vectorcraft, and other apps that mimic Adobe products. The author tested Photocraft and found its basic editing commands worked where expected, but Free Transform behaved unpredictably. Thomas describes the software as early alpha and invites developers to contribute.

AIDeveloper Brandon Thomas's Artcraft has launched seven open source apps in Rust that aim to replicate the interfaces and tools of Adobe Photoshop, Illustrator, Premiere, Lightroom, After Effects, InDesign, and Acrobat Pro. Thomas said he used Anthropic's Claude Opus 5.5 to build the clean-room replacements, with WebAssembly versions available for browser use. The apps remain in a "super early alpha" state, and commenters have pointed out many current shortcomings.

AICline says each agent runs in its own independent, secure cloud container, so users can assign a bug fix, a refactor, and a new feature at once. The pull requests can then be reviewed as they are completed.

AIVercel says Glyph Cluster, listed as stealth/glyph-cluster, is now free on AI Gateway for a limited time while in stealth. Access is restricted to paid users, the model is positioned for coding and agentic knowledge work, and prompts may be used for model improvement.

AIMastra has released Agent Controller in general availability, a runtime that hosts long-running agent sessions around the agent loop. The team says it was first built for Mastra Code and expanded to support Mastra Factory, which runs many concurrent sessions, and that memory usage in long-running Mastra Code processes dropped from 2–20 GB to 300–750 MB after optimizing UI state snapshots.

Why it matters: The post explains how the controller evolved from one developer's session to many concurrent sessions, with measured memory and storage changes useful to engineers building multi-user agent apps.

AIZed has launched the public beta of Delta, a multiplayer environment for coding with agents and reviewing their work, which replaces pull requests with shared threads. Delta is built on DeltaDB, which records edits and messages between Git commits, and it is free during the beta, with paid plans for individuals and teams to follow.

Why it matters: The post explains how Delta replaces pull requests with shared agent threads and DeltaDB, showing a concrete alternative to the GitHub review workflow.
