Deployed ZCode locally on macOS with GLM-5.3.
Currently outperforms every other open-source model on Terminal Bench 3.0 and Agents’ Last Exam (CLI).
@AutoClawAIer
GLM-5.3, the No. 1 open-source model for coding, is officially here.
GLM Coding Plan members can now complete the setup in AutoClaw and get early access to GLM-5.3.
Limited-time benefits:
-Get 1.5× usage quota when using GLM-5.3 and other GLM models through GLM Coding Plan.
GLM-5.3 ranks No. 1 among open-source models on public benchmarks including Terminal Bench 3.0 and Agents’ Last Exam (CLI), delivering stronger and more reliable performance in complex code understanding, long-horizon execution, and multi-step agentic work.
Try GLM-5.3 in AutoClaw—and put it to work on a truly complex task.

a 3x faster (up to 7x on tagged templates), byte-identical drop-in for your cn() utility.
Same API, same output, slightly bigger bundle. Pull it in if you have re-render-heavy UIs.
What it actually is
Re-implements clsx + tailwind-merge with heavy optimizations while guaranteeing identical results. The standout feature is the tagged template for
•Standard cn: ~2.5M ops/s
•cnfast: ~6.6M ops/s
•Geometric mean across 65 real workloads: 3.17x
•Biggest wins on data grids, virtualized lists, live dashboards, anything calling cn thousands of times per second.
Bundle: 9.04 KB gz vs 8.45 KB. Negligible.
How to adopt (copy-paste ready)
For a standard shadcn lib/utils.ts:
// before
import { clsx, type ClassValue } from "clsx";
import { twMerge } from "tailwind-merge";
export const cn = (...inputs: ClassValue[]) => twMerge(clsx(inputs));
// after
export { cn } from "cnfast";
Or one-liner:
npx cnfast migrate
shadcn users:
npx shadcn@latest add aidenybai/cnfast/cn
Caveats
•If you’re doing custom extendTailwindMerge for prefixes/MFE stuff, test it. The exports include twMerge/twJoin, but custom wrappers need verification.
•Static/low-re-render pages won’t notice much. Hot paths will.
•Still early (shipped yesterday). Watch the repo for a couple days if you’re paranoid about prod.
Take
This is the exact kind of micro-optimization Aiden does best. cn is one of those “invisible tax” functions that adds up in any shadcn/Next.js codebase with conditional classes. Low risk, easy rollback, real upside where it matters.
Do the swap in one of your heavier UI projects (Mermaid Studio tables or whatever has lists), run a quick before/after on a render-heavy component, and measure.

Introducing GLM-5.2: Frontier Intelligence, Open Weights
- Significant improvements in coding and agentic tasks
- Strong long-horizon capabilities with a 1M context window
- Two levels of reasoning effort: GLM-5.2 (max) pushes the limits, while GLM-5.2 (high) strikes a strong balance between performance and token efficiency
- MIT-licensed open weights
- Same API pricing as GLM-5.1

Meet Kimi K2.6: Advancing Open-Source Coding
🔹Open-source SOTA on HLE w/ tools (54.0), SWE-Bench Pro (58.6), SWE-bench Multilingual (76.7), BrowseComp (83.2), Toolathlon (50.0), Charxiv w/ python(86.7), Math Vision w/ python (93.2)
What's new:
🔹Long-horizon coding - 4,000+ tool calls, over 12 hours of continuous execution, with generalization across languages (Rust, Go, Python) and tasks (frontend, devops, perf optimization).
🔹Motion-rich frontend - Videos in hero sections, WebGL shaders, GSAP + Framer Motion, Three.js 3D.
🔹Agent Swarms, elevated - 300 parallel sub-agents × 4,000 steps per run (up from K2.5's 100 / 1,500). One prompt, 100+ files.
🔹Proactive Agents - K2.6 model powers OpenClaw, Hermes Agent, etc for 24/7 autonomous ops.
🔹Claw Groups (research preview) - bring your own agents, command your friends', bots & humans in the loop.

Your AI agent can now generate and ship videos.
HeyGen CLI is now live.
Run one command and your agent handles it all:
script → avatar creation → video → delivery
All from the terminal. Just your agent and the CLI.

Introducing SWE-Atlas.
We built SWE-Atlas as the next evolution of SWE-Bench Pro, expanding agent evaluation beyond change accuracy to better reflect the real, interactive workflows that define software development.
Results for Codebase QnA, the first eval under SWE-Atlas that measures how agents understand complex codebases through runtime analysis and multi-file reasoning, are now available.
Top models score only ~30%.
