Project
Junie is JetBrains' AI coding agent, built into its IDEs to autonomously write, test, and review code and build apps.
Google's new workhorse Flash is a model-string swap for anyone on AI Gateway, discounted through 31 December 2026. The claim worth testing is reduced tool-calling loop failures, not benchmark deltas.

JetBrains posted a CZK 315 million net loss in 2025, its first on record, on revenue that grew 6.3% to $710 million. Figures published on dev.to put the strain in costs, so teams on its IDEs should watch how JetBrains prices the AI agent it now ships in all of them.
Reality
JetBrains opened early access to Air, a plugin and 2026.3 EAP feature that runs a developer's existing coding agents as parallel sessions inside its IDEs. Air needs no JetBrains AI subscription, so a team can trial multi-agent work on the agent plans it already pays for.
Reality
Six months after introducing JetBrains Central, JetBrains has renamed it Air Governance and made it the place an organization sees and caps what agents from any vendor cost it. The IDE becomes one surface of several.

The new Junie CLI mode needs Docker, a generated build plan and a request specific enough to check, and the report it returns marks each check passed, failed or incomplete. JetBrains says it has run the agent on more than 1,500 of its own pull requests.
Reality
The Kotlin Benchmark grades agents on 105 verified repository tasks. Its token column shows setups that solve within a few tasks of each other burning between 66,000 and 777,000 tokens per fix.
Reality
JetBrains put two frontier models through the same coding agent, which scored them as a tie on tasks solved even though the runs differed by 47% in steps and 2.25x in dollars, and that gap is what procurement actually pays.
Reality
JetBrains has taken the assembly work out of running a coding agent offline. What it could not take out is the hardware, and that is now the thing deciding who adopts.
Reality
JetBrains traced a model through fifteen C# refactoring tasks and found it simulating structure with sed, git and the compiler. Wiring in Rider's real engine cut median time by 83%.
Reality
JetBrains reports 90% of professional developers use coding agents weekly. The number that matters for tooling bets is not adoption but conversion, where Claude Code is far ahead.
