agentgateway 1.5 puts one Rust proxy and one policy language in front of LLM APIs, MCP tool servers and A2A agents. Its per-caller tool authorization is the real thing; its open-by-default settings are not production-ready.
goose 1.52 is a provider-neutral, MCP-native agent with a desktop app, a CLI and reusable recipes, now under the Linux Foundation. It is flexible and well governed; out of the box it is autonomous, unsandboxed and too quick to report success.
Tracel tagged Burn v0.22.0-pre.4 and CubeCL v0.11.0-pre.4 on the same day (2026-09-22). Pre-release only—not stable 0.22 / 0.11. LAMB, einsum, AMDGPU and CUDA-LLVM backends; dual MIT/Apache.
HF tagged tokenizers v1.0.0-rc.2 (2026-09-21): same API and token IDs as v0.23, performance refactor. Install with cargo add --pre. Encode 3–30× and related figures are HF/tokbench (M4 Max), not desk-measured.
smartcomputer-ai/lightspeed describes a deterministic Rust agent harness on Temporal for durable managed-agent workflows, with Postgres/optional S3 and a TypeScript/React UI. Early public repo—README claims only; Apache-2.0.
GitHub’s Stephen Toub details rewriting the Copilot agent runtime from TypeScript/Node into 800k+ lines of production Rust, shipping incrementally with an embeddable C ABI. Latency figures are GitHub eng benchmarks without model or network time.
A dated brief on NVIDIA’s Sep 2026 CUDA Rust post: two early-stage kernel tracks — cuda-oxide (SIMT, early alpha) and cutile-rs (Tile) — neither production-ready. Correctness demo only; no perf claims.
A dated changelog brief on Eric Buehler’s mistral.rs v0.9.3 (tagged 2026-09-07): FP8 and DFlash decode, NVFP4 with cuTile Blackwell, and stronger Anthropic Messages / Claude Code server support. Not affiliated with Mistral AI.
