Summary

  • Gemini 3.8 Flash is tuned for long jobs and spends more tokens per task, exploring directories, retrying code, and running verification steps before finishing.
  • Gemini 3.8 Flash is available in Junie, in both the IDE plugin and Junie CLI, with a limited-time introductory offer of 75% off.
  • 3.7 Flash was built for quick, reliable answers; 3.8 Flash takes a loop-based approach.

Google’s Gemini 3.8 Flash, designed for long-running coding tasks, is now available in Junie via the IDE plugin and Junie CLI, with a limited-time introductory offer of 75% off.

JetBrains describes 3.8 Flash as tuned for multi-step engineering work that requires real exploration, building on the company’s Flash lineage.

A LOOP-BASED APPROACH FOR COMPLEX DEVELOPMENT TASKS

Unlike its predecessor focused on quick, reliable answers, Gemini 3.8 Flash spends more tokens per task, exploring directories, retrying code that doesn’t work, and running verification steps before deeming a job complete. TechStaged has also covered Google Gemini Adds Free Full-Length SAT Practice Tests, Vetting Content With The Princeton Review.

It breaks goals into sub-tasks, writes scripts to reproduce bugs, runs tests via tool calls, and checks its own changes before finishing.

Google’s DeepSWE v1.1 benchmark shows the model can outperform many larger frontier models on long-horizon, real-world development tasks while costing less.

AVAILABILITY, PRICING, AND MODEL CHOICES

Gemini 3.8 Flash is available in Junie in both the IDE plugin and Junie CLI, with a limited-time 75% discount.

If a task is small, Gemini 3.7 Flash remains an option, offering quicker, cheaper results per token.

The offer requires no setup or waitlist.

JUNIE LOCAL AND BROADER CONTEXT

The blog post also references Junie Local, a project to enable local inference across hardware configurations, with an initial release that supports MacBook M5 using Qwen3.6-27B.

Junie Local is described as running the full AI coding agent on a Mac, with one command, no configuration, no tokens, and claims of code remaining on the user’s machine, described as completely free.
