Gemini 3.5 Flash
Timeline (last 90 days)
The small model GLM5 paired with an evolved harness beat the stronger model Gemini 3.5 Flash running the default harness, and when the harness evolved for Gemini was handed unchanged to the small model, the latter's coding score immediately jumped by 17 points.
Google validated Harness2 on two models, Gemini 3.5 Flash and GLM-5, covering three types of benchmarks: legal, office, and professional work.
Testing with two models from different families, Gemini 3.5 Flash and GLM-5, shows that the Harness2 method itself does not depend on specific model characteristics.
In 2026 Google shipped four major Flash architecture versions: 3.5 Flash (May 19), 3.6 Flash (midsummer), 3.7 Flash (late summer), and 3.8 Flash (early September), while the Pro tier received no updates.
In the test, the top tier (Overall 83.33) is occupied by Gemini 3.5 Flash, Claude Sonnet 5, and Claude Opus 5.
Compared to 3.5 Flash, 3.6 Flash reduces average output tokens by approximately 17%, with some code tasks seeing reductions of up to 65%.
