RadixArk just open-sourced Miles, an enterprise-ready RL framework designed specifically for post-training large-scale LLMs and VLMs. It pairs SGLang for high-throughput rollouts with Megatron-LM (or PyTorch FSDP2) for distributed training.

Anyone running RL at scale knows the usual headaches: engine crashes, off-policy divergence, MoE routing mismatches, and massive weight synchronization overhead. Miles targets those exact infrastructure bottlenecks.

Features:

• Token-in-Token-Out (TITO): Preserves exact rollout tokens and metadata across black-box harnesses and environments without detokenizing and retokenizing, avoiding encoding mismatches.
• P2P RDMA Weight Updates: Synchronizes weight updates between rollout engines and training workers in seconds—even at trillion-parameter scales—without pipeline stalls.
• Rollout Routing Replay (R3): Records expert routing choices during SGLang rollouts and replays them in Megatron-LM’s forward pass, eliminating MoE routing divergence that causes training instability.
• Fully Async & Decoupled RL Pipelines: Decouples rollout and training workers with customizable on/off-policy schedules and async evaluation to maximize GPU utilization.
• In-Place Fault Recovery: Automatically recovers killed or crashed SGLang rollout engines and resumes the run in-place without pausing or restarting the training cluster.

CodeRabbit just released a new product called CodeRabbit Security. It is built to find and fix application-level vulnerabilities that standard rule-based SAST tools usually miss (like business logic flaws, IDORs, or prompt injections).

Instead of relying on static rules, it uses specialized AI agents to act more like an attacker—mapping out how your code actually interacts across services.

Features:

• Repo-Wide Context Mapping: It builds a reachability graph of your entire codebase, tracing inputs from entry points to sinks to catch complex flaws (like race conditions or injection chains) that span multiple files.
• Independent Verification (Less Noise): Before flagging a vulnerability, a secondary verifier agent checks if the path is actually reachable and exploitable, aggressively weeding out false positives.
• Auto-Repairs via PRs: When it confirms a vulnerability, it doesn't just open a dashboard ticket. It scopes the remediation and submits a reviewable pull request (or a stacked PR) directly into your workflow.
• Deep Scans + Active PR Monitoring: It runs continuous security reviews on active pull requests to catch new issues, while also allowing you to run scheduled "AI Deep Scans" to find vulnerabilities in historical, already-committed code.
• Seamless Workflow Integration: It is a fully cloud-based SaaS that hooks directly into GitHub, GitLab, Azure DevOps, and Bitbucket—meaning there are no local hardware requirements or complex infrastructure setups.

Agents often hit a "context rot" wall on complex tasks, bloat their context window with junk, and forget their original prompt. To fix this, the team at Arcee AI just open-sourced nac (Apache-2.0) to separate the temporary context needed for an action from the persistent state needed to finish a project.

Features:

• Context Bloat Eliminated: Workers execute tasks and return concise summaries ("episodes"). The noisy raw context is permanently discarded.
• Parallel Execution (DAG): Safely run multiple autonomous worker threads concurrently (e.g., set up an environment while exploring code).
• Native Sandboxing: Isolates experimental code changes directly on your host machine using Git worktrees (sandbox-worktree)—no Docker needed.
• Zero Local GPU Needed: Requires <100MB disk and 512MB RAM. Bring your own LLM API keys (OpenAI, Anthropic, DeepSeek, or Arcee).
• MCP & Tooling: Ships with an MCP server. Interactive coding agents (like Claude Code or Codex) can use nac as a background tool while keeping your main chat clean.

pgbot is a new open-source, Go-based utility that inspects database health, tracks metric drift, and feeds structured diagnostics straight to your terminal or AI coding assistant. It runs as a single static binary that connects read-only, evaluates database health, and writes local baselines to track drift over time. Beyond its use as a standard command-line diagnostic tool, it includes native Model Context Protocol (MCP) support so AI coding assistants can query database metrics directly.

Key Features:

• Strictly Read-Only Safety: Non-destructive by design, utilizing standard pg_monitor roles and transaction-level read-only guards to ensure production data is never mutated.
• Model Context Protocol (MCP) Support: Plugs natively into AI environments like Claude Desktop, Cursor, or Claude Code via pgbot mcp to let models run deterministic diagnostics.
• Baseline-Driven Drift Tracking: Stores local metric snapshots over time to instantly flag regressions like sudden slow queries, surging dead tuples, or cache drops.
• Double-Sampled Live Rates: Computes actual throughput, WAL rates, and I/O activity by double-sampling cumulative performance counters rather than showing raw totals.
• Zero-Friction Deployment: Ships as a single static binary via script, Homebrew, or Docker, with built-in configurations for AWS RDS, Supabase, and Neon.

OpenRouter released Ori Harness, a lightweight CLI wrapper that lets you run developer coding agents—like Claude Code, Codex, OpenCode, Prime Agent, and DeepSeek Harness—directly through OpenRouter without changing your workflow.

The CLI software itself is free to use, with traffic billed at standard pay-as-you-go OpenRouter model rates.

Features:

• Universal Model Hot-Swapping: Force any supported agent CLI to use any of OpenRouter’s 500+ LLMs via a single --model flag (e.g., ori claude --model openai/gpt-5.2 or ori prime-agent --model google/gemini-3.6-flash).
• OAuth Auth & Environment Cleanup: Authenticates once via OpenRouter browser OAuth instead of managing scattered auth.json or models.json files. It automatically strips local API keys (like ANTHROPIC_API_KEY or OPENAI_API_KEY) during execution to prevent silent provider fallback collisions.
• Transparent CLI Passthrough: Wraps the actual agent binaries found on your system PATH. All native keybindings, subcommands, and trailing flags pass straight to the underlying agent untouched (e.g., ori codex --full-auto).
• Centralized Org Guardrails: Automatically enforces your OpenRouter dashboard policies—such as model allowlists, rate limits, and monthly spending caps—across every local CLI run without needing local configuration files.
• Unified Multi-Agent Billing & Analytics: Aggregates token consumption, prompt caching data, and billing across all your different coding tools into a single OpenRouter account balance and breakdown dashboard.

Dots Studio just released the open-weight preview of dots3-note. It's a 280B MoE (16B active) multimodal model (text, vision, audio) optimized for complex reasoning, coding, tool use, and ultra-long-horizon agent tasks.

They also introduced a new reinforcement learning approach called TEMPO (Test-time-scaled Value Estimation with Macro-step Policy Optimization). Instead of relying entirely on standard RLHF, TEMPO uses recursive self-critiquing to let the agent evaluate its own reasoning and update its memory in unfamiliar environments before completing a long-horizon task.

Features:

• Efficient MoE Architecture: With 280B total but only 16B active parameters, it delivers massive model performance while keeping the active inference compute overhead relatively low.
• 512K Context Window: Built to natively handle massive inputs like full codebases, deep research documents, and long-term memory for agentic workflows.
• Native Multimodal Inputs: Processes text, images, video, and audio out of the box, eliminating the need to stitch together separate perception models for real-world agent tasks.
• Permissive Licensing: Released under the Apache 2.0 license, allowing for unrestricted local deployment, fine-tuning, and commercial integration.
• Plug-and-Play Deployment: Immediate, out-of-the-box support for standard deployment stacks with quickstart code and Docker images available for vLLM, SGLang, and Transformers.

Perplexity just open-sourced the Perplexity Search SDK, bringing its "Search as Code" architecture directly to external developers.

Instead of treating web retrieval as a monolithic tool call that dumps raw results into an LLM’s context window, this SDK exposes retrieval primitives directly in Python. Your agent can execute searches, fan out queries, deduplicate links, and extract snippets programmatically in the runtime before feeding only the essential context to the model.

Key Features:

• Composable Retrieval Primitives: Call live web search (pplx_srch_sdk.search.web) and snippet extraction (pplx_srch_sdk.content.snippets) as standalone modular methods.
• In-Runtime State Management & Filtering: Fan out multiple parallel queries, deduplicate URLs, and rank results entirely within your application runtime, keeping intermediate clutter out of the context window.
• Context Window & Token Optimization: Drastically reduces token bloat by passing only filtered, query-relevant page snippets rather than unstructured web pages into your LLM prompts.
• Native Synchronous & Async Support: Ships with both synchronous execution and a built-in AsyncPplxClient designed for high-concurrency, retrieval-heavy multi-agent workflows.
• Agent-First Architecture: Built to be driven directly by coding agents via the official pplx-search-sdk skill, backed by a precompiled native core for high performance.

The Solid 2.0 Release Candidate (RC) is officially out. The overarching architectural shift in this release is that async is no longer treated as a separate condition to manage—it is now a native property of the reactive graph itself.

Features:

• First-Class Async Handling: Computations can now return Promises directly. You no longer need special primitives to absorb async data; standard <Loading> boundaries and isPending states handle it natively without manual null checks.
• New Rust-Based Compiler: The default Vite plugin now uses a compiler toolchain written in Rust (on top of Oxc). This delivers massive build performance gains, including a 355x speedup for large modules compared to the legacy Babel preset.
• SolidStart is now "Start Mode": Metaframework capabilities have been absorbed into core. By simply adding start: true to your Vite plugin, you get an integrated serving layer, SSR, and file-system routing. SolidStart as a separate metaframework is being retired.
• Core Server Functions: The "use server" directive is now built into the core web package. You can write backend RPCs, validation, and auth directly in your Vite app, and the compiler automatically ensures that server-only code never reaches the client bundle.
• Draft-First Stores: State management has been drastically simplified. Complex APIs like produce and createMutable are gone. Store setters now natively hand back a draft that you can mutate directly, eliminating the need for write-back workarounds.

Z.ai just launched a new tool called OpenVuln. It’s a public vulnerability intelligence platform powered by their GLM model that runs autonomous security audits on open-source codebases.

You just paste a public GitHub repository URL, and the AI engine scans the entire codebase to hunt for vulnerabilities. It’s currently hosted as a Hugging Face Space and is free to use.

Features:

• Zero-Setup Scanning: No need to configure CI/CD pipelines or install local dependencies; just paste the repository URL and let the engine run.
• Responsible Disclosure Enforcement: Aggregate security metrics (number of bugs, severity levels) are public, but detailed code flaws remain private and accessible only to verified repository maintainers until public disclosure.
• Deep Contextual Analysis: Powered by the GLM model, the engine moves beyond simple static pattern matching to analyze complex logic flows and multi-file dependencies.
• Severity Categorization: Automatically triages findings into Critical, High, Medium, and Low severity tiers so maintainers can prioritize immediate patches.
• Asynchronous Auditing: Full repository scans run in the background (typically taking 12+ hours for deep audits), allowing you to submit your project and review the dashboard when it finishes.

Mixedbread just released Toast 1, a model specifically designed as a retrieval subagent. It fully takes over the search loop—decomposing queries, gathering evidence, and curating context—before handing a clean, token-efficient evidence package back to your generalist reasoning models (like GPT-5.6 or Claude).

Features:

• Subagent Architecture: It is designed to plug directly into your stack to handle the heavy RAG lifting, freeing up your primary model's compute and context window.
• Proven Token Efficiency: Benchmarks on the Harvey LAB firm-knowledge dataset show it maintains 100% answer quality while using 3.5× fewer tokens compared to a vanilla agent.
• Backend Agnostic: It is engineered to run over your existing retrieval indexes, meaning you do not need to migrate your current database backend to use it.
• Immediate Workflow Integration: You can add it as a retrieval tool to your stack in minutes via their Chat Completions API or by using their pre-built golden harness.
• Native Coding Agent Support: You can pipe it into coding agents directly using standard package manager commands (npx skills add mixedbread-ai/skills) or through their OpenCode integration.
