01What GLM 5.3 Is and How It Works

GLM 5.3 is a free frontier-level AI model you can use right now through the Zedcode app. It performs at the same level as models like Fable 5 and Claude Fable 5 but you do not need to pay anything to use it. New users get access on the free tier with no subscription or credit card required.

In this episode Julian Goldie explains how to get started and why GLM 5.3 is a big deal for anyone who wants powerful AI without spending money.

GLM 5.3 works inside Zedcode, which is a downloadable app that looks similar to tools like Claude Code. Once you sign up you can select GLM 5.3 as the model for your project. From there you set permissions and start building apps, games, tools, and automations.

The model handles coding tasks well and can also plug into AI agents and command-line interfaces.

02Main Features of GLM 5.3 in Zedcode

  • Free tier access – New users can try GLM 5.3 without paying. No credit card needed to start.
  • Project-based interface – Select your project inside Zedcode, pick GLM 5.3, and change permissions as needed.
  • Automation tools – The left sidebar includes search, automation, skills, and new tasks to organize your work.
  • Frontier performance – GLM 5.3 scores very close to or even better than top models on several benchmarks.
  • Open weights coming – The model will be released as open weights on Hugging Face soon, making it open source.
  • Agent and CLI support – You can plug GLM 5.3 into AI agents and use it from the command line.

03How to Set Up GLM 5.3 for Free

  1. Download Zedcode – Go to the official site and install the Zedcode app on your computer.
  2. Sign up for a free account – Create an account. You do not need to enter a credit card.
  3. Select your project – Inside Zedcode, choose the project you want to work on.
  4. Pick GLM 5.3 as the model – From the model options, select GLM 5.3.
  5. Adjust permissions – Set the permissions for the model as needed for your project.
  6. Start building – Use the free tokens to build apps, games, tools, or automations. You get a limited number of free tokens but it is enough to try many tasks.

04How to Use GLM 5.3 – Examples from the Episode

In this episode Julian Goldie shows how he uses GLM 5.3 inside Zedcode to build a website. You can also use it to create apps, games, tools, and automate any task. The left hand side of Zedcode gives you search, automation, skills, and new task options to organize your workflow.

One of the smartest ways to use GLM 5.3 is to let Claude orchestrate it. Julian explains that you can tell Claude to build stuff with Zedcode directly. That way you do not need to manage the model yourself—your AI assistant handles it.

This makes the process faster and more hands-off. You can also run multiple tasks on the free tier, though the token limit is small.

05Results and Comparisons from Benchmarks

GLM 5.3 competes directly with top frontier models. According to the episode, on Terminal Bench 2.1 GLM 5.3 scores 88.2 while Fable 5 scores 88. On Terminal Bench 28.3 GLM 5.3 gets a score while Fable 5 gets 33.7.

The difference is only one to three points, with a maximum of five points across the benchmarks.

On SWE Marathon v1.1 GLM 5.3 actually outperforms Claude Fable 5's best model. GLM 5.3 scores 42.5 versus 33.1 from Fable 5 and 42.5 from GPT 5.6 Sol. This shows that GLM 5.3 is a strong choice for coding and software engineering tasks, especially since it costs nothing to use.

06Tips, Limits and Mistakes to Avoid

  • Free tokens are limited – You do not get many tokens on the free tier. Be careful not to waste them on large projects right away.
  • Open weights does not mean local use – GLM 5.3 will go open weights on Hugging Face soon, but you need a very powerful local setup to run it. Do not expect to run it on a normal laptop.
  • Best for coding – GLM 5.3 performs best on coding tasks. Do not use it for unrelated work where other free models might be better.
  • Use Claude to manage it – Julian recommends letting Claude orchestrate GLM 5.3 inside Zedcode to save time and avoid manual management.

07Who GLM 5.3 Is For and Why It Matters

GLM 5.3 is ideal for developers, coders, and AI enthusiasts who want to use a frontier-level model without paying. If you are building apps, games, tools, or automating tasks, this free model gives you a real chance to experiment and create. It matters because it lowers the barrier to high-quality AI.

You do not need a subscription or credit card to try it.

For people learning to code with AI or building agent workflows, GLM 5.3 is a practical choice. It also matters because it will become open source soon, which means the community can inspect, modify, and share improvements. If you want to stay on the cutting edge without spending money, this model is worth your time.
