I'd like to know more about what is powering Junie under the hood.

> According to SWEBench Verified, a curated benchmark of 500 developer tasks, Junie can solve 53.6% of tasks on a single run

That's nice I guess, but why isn't this an entry on the actual https://www.swebench.com/#verified website? (Also: 53% isn't that impressive these days, Claude Sonnet can reach 63%)

Junie has been amazing for me, completely replaced my payments for Claude Code and Cursor. And it was free (until today). It's the least aggressive agent i've used, no complete re-writes or even close, And is able to achieve about 95% of what I ask of it

The only downside - which might be fixed in the newest release - is that it completely forgets context between messages - even in the same message window. But that feels like both cost cutting and easy to fix

My biggest issues with Claude Code and Cursor for what its worth:

Claude Code: Price, plus when it doesnt get things right, within a few messages it ALWAYS just creates a new file entry point with some demo console.logs that do nothing but show messages, and claims to have succeeded in what I asked

Cursor: Will break some functionality in my web application while fixing or creating others, about 80% of the time

Summary:

- JetBrains AI tools (AI Assistant and Junie coding agent) are now available under a single subscription starting with version 2025.1.

- There are three tiers: AI Free, AI Pro, and AI Ultimate.

- The free tier offers unlimited code completion, local AI models, and credit-based access to cloud AI assistance and Junie.

- AI Assistant supports Claude 3.7 Sonnet and Google Gemini 2.5 Pro.

- Junie is powered by Anthropic's Claude and OpenAI models.

It's not clear whether AI Free will be available in Community Edition IDEs or not.

Update: From the AI Plans & Pricing page, there's a tooltip that says: "The free tier is not available in the Community Editions of PyCharm and IntelliJ IDEA."

This quote claims it is 'powered by Claude'

“JetBrains and Anthropic share a commitment to transforming how developers work. Developers rely on Claude’s state-of-the-art performance in solving complex, real-world coding tasks. We’re excited to see how Junie, powered by Claude, will help the global developer community create innovative things within the trusted JetBrains IDEs that customers love.” Mike Krieger, Chief Product Officer, Anthropic

Kind of confusingly, in today's release of Rider 'Junie' is mentioned nowhere I can find. The AI assistant tab, which was already available (paid), just has options to pick from popular models (4o, o1, o3, Gemini, Claude) or LM Studio / Ollama

> On top of all that, the All Products Pack and dotUltimate subscriptions will now come with AI Pro included.

Well, colour me surprised. I've used JetBrains as an an example of a pretty decent company in the past (e.g. the way they remind you your subscription is up for renewal a couple of months in advance, so you have all the time in the world to unsub if you like), but I wasn't expecting them to just add this to the existing subscriptions.

Under "availability in products", they specifically say that the Free tier is not available on Community Edition.

You can add a .noai file to the root of your project to disable AI support.

Errr, that 404s now. I hope the functionality still works.

Here's the cached version:

> Restrict usage of AI Assistant for a project Create an empty file named .noai in the root directory of the project.

> When this file is present, all AI Assistant features are fully disabled for the project. Even if this project is opened in another IDE, the AI Assistant features will not be available.

Junie isn't available for all of the IDEs yet, so it's not yet available in Rider. As of today it's available for PyCharm, IntelliJ, WebStorm and GoLand: https://www.jetbrains.com/junie/
