Cactus open-sourced Needle 2, a 45M-parameter agentic LLM in a single 14MB binary that runs a full tool-calling session in 28MB of RAM. 500 tok/s on a Raspberry Pi 5, ESP32-S3 class parts, Apache 2.0. Here is what the benchmarks actually show.
Your coding agent can write the code. With Railway's official MCP server it can ship it too: create the project, deploy the service, assign a domain, tweak variables, and read logs, all as tool calls. The complete one-hour build.
GitHub shipped a Java-native Copilot SDK (1.0.7-preview.1) with @CopilotTool annotations, virtual-thread support, Jakarta EE and Spring composition, and BYOK mode that works against any OpenAI-compatible endpoint with no Copilot subscription. Here is what changed and what it unlocks.
A new arXiv paper probes six widely used open-source agent frameworks and finds the barrier semantics of approval gates, cancellation, and timeouts hold on none of them. A sibling branch can execute while the user is rejecting another one, and replay can double-execute. The fix is a verified external gate called SoundGate.
Vercel Sandbox now polices all outbound traffic on the host, outside the microVM, with SNI-based domain policies, CIDR rules, host-level credential injection, and a deny-all default. Here is why a network boundary is the half of agent isolation that VM escapes missed.
A new ASE 2026 framework injects server errors, truncated responses, and corrupted tool calls into live agent systems at the HTTP layer. Every system degrades, pass@1 drops up to 50 points, and the ranking stays the same no matter which LLM is behind it.
A new arXiv paper builds a deterministic monitor on top of SWE-agent that watches long agent trajectories and only calls an advisor LLM when the run actually drifts. Resolution rates go up by up to 15.2 points at an extra $0.08 per instance, and the paper argues the expensive approach is re-planning from inside the loop.
Meta open-sourced Muse Glimmer, a 30B Apache 2.0 multimodal agent model that runs in a 24GB envelope at up to 233 tok/s. MCP Atlas 75.5, SWE-Bench Verified 76.0, 131K context. Here is what the numbers actually say.
GPT-5.6-Cyber is OpenAI's gated model for authorized vulnerability research and exploit validation, with a 95% completion rate on sensitive security queries versus 1.5% for the base model. It already produced a fixed Chrome CVE. Here is what actually shipped and who gets it.
MCP just became stateless, which means your own MCP server is now just an HTTP endpoint that deploys like any web service. Build one with an agent, deploy it on Railway, and point opencode or Claude Code at the public URL. The full build, start to finish.
A support page nobody talks to is a support page doing half its job. ElevenLabs Agents gives you a two-way voice agent grounded on your own docs: ASR, LLM, TTS and turn-taking in one platform, a widget you embed in five lines, and CLI or MCP management so your coding agent can run it. The complete one-hour build.
Claude Code v2.1.224 lets one running session message another over a first-party channel - plain text, permission-aware, with approval dialogs when bypass-mode sessions talk to each other. Here is what ships, how delivery and inbound controls work, and where the feature stops.
The agent finishes, the summary scrolls past, and you will read it later. Build the fix: a coding agent that ends every run with a plain-language summary, piped into ElevenLabs text-to-speech and out as an MP3 you can listen to on the way to work. The complete one-hour build.
