## Tracked benchmark scores

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| BullshitBench v2 | 66% | [BullshitBench](https://github.com/petergpt/bullshit-benchmark) | Given a confidently-worded but nonsensical prompt, does the AI spot that it makes no sense and push back — instead of playing along and inventing an answer? The score is how often it clearly called out the nonsense. Higher is better. |
| SWE-Bench Pro | 54.2% | Lab | Can the AI fix real bugs in real software? It's handed actual problems from open-source projects and has to write code that genuinely solves them. Higher is better. |
| Terminal-Bench 2.1 | 54% | Lab | Can the AI work in a command-line terminal — running commands and finishing technical setup tasks the way a developer would? Higher is better. |
| BU Bench | 49% | Lab | Can the AI drive a real web browser to finish tasks — clicking, filling forms, and navigating sites the way a person would? Run by Browser Use on their BU Bench task set. Higher is better. |
| OSWorld-Verified | 74% | Lab | Can the AI actually operate a computer — clicking, typing, and using real apps — to finish tasks on its own? Higher is better. |
| GDPval-AA v2 | 1140 | Lab | economically valuable knowledge work (v2, re-based Elo) |

## About Gemini 3.5 Flash-Lite

Gemini 3.5 Flash-Lite joined Google's model lineup in July 2026 as an efficiency-focused model for high-throughput tasks. Google positioned it for document parsing, lightweight agent work and frequent data-processing requests. It accepted text and multimodal inputs, including images, audio, video and PDFs, while producing text responses rather than generating media.

Its documented input limit was roughly one million tokens, with support for functions and structured output. That combination suited workflows such as extracting fields from files or assigning routine steps to a smaller model within a larger agent system. The Flash-Lite tier offered a different deployment tradeoff from the main Flash model, with task complexity, response time and per-request cost guiding the choice.
