Feature Drop: Google Gemini 4 Argon Now Available
Published on October 13th, 2026
Google's first Gemini 4 model, Gemini 4 Argon, is now available on Omnifact. Released as Google's new flagship reasoning model, Argon is built for sustained, multi-step work across software engineering, financial and legal analysis, and large document collections. While Gemini 3.5 Flash and Gemini 3.8 Flash remain the fast choices for everyday prompts, Gemini 4 Argon steps in when an assignment requires deeper verification and planning.
Built for Sustained Reasoning and Deep Work
Earlier Pro releases like Gemini 3.1 Pro introduced deep-thinking capabilities in preview, but complex tasks often hit output limits or lost precision across long documents. Gemini 4 Argon replaces those preview limits with a production-ready model built for multi-step problem solving.
On Google DeepMind's October 2026 evaluations, Argon ranks first on the Vals Index at 68.9% across finance, coding, legal, and tax tasks, and leads AutomationBench for end-to-end business workflows. In practice, that means fewer manual follow-ups when an agent searches a Knowledge Base, cross-checks filings, or edits code across multiple files.
Gemini 4 Argon in the Google Lineup
Organizations can pair Gemini 4 Argon for heavy analytical work with Gemini 3.8 Flash for fast daily tasks:
| Area | Gemini 4 Argon | Gemini 3.1 Pro | Gemini 3.8 Flash |
|---|---|---|---|
| Primary Role | Deep reasoning, complex coding, legal and financial synthesis | Previous Pro reasoning baseline (preview) | Fast everyday assistance and high-volume tasks |
| Context Window | 1M tokens | 1M tokens | 1M tokens |
| Max Output | 64k default / up to 1M tokens | 64k tokens | 64k tokens |
| Reasoning Effort | Low, Medium (default), High | Configurable thinking | Configurable thinking |
| Token Pricing (per 1M) | $2.00 input / $10.00 output (intro through Nov 30, 2026) | $2.00 input / $12.00 output | $0.75 input / $3.75 output (intro through Dec 31, 2026) |
| Knowledge Cutoff | March 2026 | January 2025 | March 2026 |
Starting December 1, 2026, standard list pricing of $4.00 per million input tokens and $20.00 per million output tokens applies.
Put the 1M Context Window to Work
With a 1-million-token context window and strong recall across long inputs, Argon handles large workloads in a single conversation:
- Document synthesis in Spaces: Analyze full contract suites, audit reports, and financial documents in Spaces synced via Connected Sources.
- Multi-file coding and reviews: Run large-scale code migrations, dependency upgrades, and security reviews across repositories.
- Adjustable Reasoning: Switch between Low, Medium (default), and High using the Reasoning controls in the Chat Input model picker to match thinking depth to the task.
