Choose Gemini 4 Argon if…
- you need chat and assistant products
- you need google cloud shops
- you need price-sensitive frontier work
Wins the popularity contest: first on Arena, mid-pack on the index, and priced like a workhorse.
Caveats: Google's public pricing page did not list Argon when read; the blended figure is Artificial Analysis' estimate.
Choose Gemini 3.5 Flash-Lite if…
- you need classification and extraction pipelines
- you need routing and triage
- you need agentic search at volume
Google's volume tier: 1M context, ~430 tok/s, $0.30/$2.50, and a respectable Arena rank 70. The right default for classification, extraction and routing at scale. Not a reasoning model in any serious sense (AA 22).
Caveats: Output at $2.50/1M is pricier than GPT-6 Luna or GLM-5.3-Flash for the intelligence you get; the win is speed, not cost per token. Google has shipped three Flash-Lite generations in 2026; plan for deprecation cycles.

Which is cheaper, Gemini 4 Argon or Gemini 3.5 Flash-Lite?
Google does not publish a simple list price for Gemini 4 Argon; Artificial Analysis estimates a blended $1.99 per million tokens (three input to one output). Gemini 3.5 Flash-Lite costs $0.30 per million input tokens and $2.50 per million output tokens on Google's list price (Gemini API Pricing, read Oct 11, 2026).
Scores come from the Models at Work leaderboard: Score is 0 to 100 and computed, not typed: 55% independent evals (Artificial Analysis, Arena, Scale SEAL, Epoch, each scaled against its natural floor and the best score in this table, then averaged), 15% blended price on a fixed log scale ($0.05 per million is 100, $60 is 0), 15% practitioner sentiment from Signals and community threads, 15% operational fit (context window, open weights). A missing component drops out and the rest are reweighted. A model with no independent eval yet is provisional and ranks below every measured one. Within three points is a tie. Vendor-published figures are labelled and never counted. Prices are vendor list prices where published; blended figures assume three input tokens per output token.
