01What Is Claude Opus 5.5 and How It Works
Claude Opus 5.5 is a new AI model from Claude that was released recently. It is a thinking model, which means it can reason through complex problems and handle long tasks on its own. In this episode, Julian Goldie explains that it is much better than the previous Opus 5, which was disappointing.
The model works by letting you pick it inside the Claude app. Once you switch, you can give it tasks like building games or writing code. It uses a lot of tokens, but your plan covers them.
It is designed for long-form tasks, so it can run for hours without stopping. Julian says it is very powerful and fun to use.
02Main Features of Claude Opus 5.5
Julian highlights several features that make Claude Opus 5.5 stand out. First, it is cheaper than Claude Fable 5.1. You get more tokens on your plan, so you are not charged extra.
Second, it is very good at long tasks. It can run for hours on its own.
Another feature is the effort level. You can set it to low, medium, or high. Julian uses medium for most tasks and says it gives good results.
The model also creates impressive visuals, like open-world games and animated videos. It has a skill called remotion for video animations. It even built 50 different game builds by itself while Julian was doing other work.
- Cheaper than Fable 5.1.
- More tokens on your plan.
- Designed for long autonomous tasks.
- Adjustable effort levels.
- Works with tools like Hermes and Obsidian.
03How to Get Started with Claude Opus 5.5
Getting started with Claude Opus 5.5 is easy. Julian walks through the steps in the episode. Make sure you have the Claude app or access to the Claude platform.
- Open the Claude app on your device.
- Check for updates in the app to make sure you have the latest version.
- Go to the model selection area and choose Opus 5.5.
- Start using it right away for your tasks.
- Optionally, set the effort level to medium for balanced results.
Once you switch, you can use it for chatting, coding, or building projects. Julian uses Claude desktop app for coding instead of chat. You can also integrate it with tools like Hermes for agent workflows.
04How to Use Claude Opus 5.5 for Real Tasks
Julian shows several ways to use Claude Opus 5.5 in the episode. He tested it on games and automations. For games, he had the model build an open-world racing game.
It worked on the first try and looked beautiful. He also built a parachute drop game and an RPG game. Julian says games are good for testing because they show logic and planning.
For automations, he shows an example with Hermes. You can plug Opus 5.5 into an agent system using the official Hermes plugin from Neuze Research. This lets you run it with your favorite workflows.
Julian also uses Obsidian for memory. All his agents update an Obsidian vault with notes every few hours, so the memory is always fresh. He says this is a simple way to keep AI agents in sync.
05Benchmarks and Comparisons from the Episode
Julian ran tests on Goldiebench, his own benchmark suite. He compared Claude Opus 5.5 with other models like Claude Fable 5.1, Claude Opus 5, GPT-6 Astra, and GPT-6 Sol. He found that Opus 5.5 crushes Fable 5.1 and beats Opus 5 clearly.
It even beats GPT-6 Astra on some tests, though Julian says you should test it yourself.
The benchmarks show that Opus 5.5 is a frontier model. It is more powerful than most others, except maybe GPT-6 Astra, which Julian likes. He says Opus 5 and Grok 4.7 are not as good.
Julian also mentions that GPT-6 Luna and Soul dropped the same day, but they are not as exciting. He suggests sticking with Opus 5.5 or GPT-6 Astra for thinking tasks.
06Tips, Limits, and Mistakes to Avoid with Opus 5.5
Julian shares some tips for getting the best results from Claude Opus 5.5. First, use medium effort level. It works well for most things.
Second, always double-check the details. The model sometimes misses small parts, especially when building apps or games. Third, test the model yourself before trusting benchmarks.
Julian did his own tests, and you should too.
One limit is that the model can run into usage limits if you use it too much, but with Opus 5.5 you get more tokens than with Fable 5.1. Another mistake is not checking for updates in the Claude app. You need to make sure you have the latest version.
Julian also warns not to compare it to models like Grok 4.7, which are not as good. Stick to the top models for serious work.
07Who Should Use Claude Opus 5.5 and Why It Matters
Claude Opus 5.5 is for anyone who uses AI for serious work. If you build apps, games, or run automations, this model can save you time. It is also good for knowledge work, like coding with Claude Code or co-working.
Julian says it is one of the only two models worth paying attention to right now, along with GPT-6 Astra.
Why it matters? Because it is powerful and affordable. You get a lot of value for your subscription.
It also handles long tasks on its own, so you can set it and forget it. Julian thinks it is very powerful, even scary powerful. He recommends trying it on Goldiebench for free to see what it can do before you pay.
