Gemini 4 Pro / Flash: benchmarks, hands-on tests and leaks

The author posts a video captioned only "Gemini 4 Pro," without describing what was tested or any conclusion.

The author says Gemini 4 Pro is very strong in areas like design and 3D modeling but rough in others, because Google specializes models for fields like math rather than building all-round general models.

LuminaBench replies that Gemini 4 Pro can generate exploded views showing internal components with part names.

An unidentified Google model has surfaced in Arena testing, rumored to have 10M-token context, a big coding jump and persistent memory, possibly a Gemini 4 checkpoint.

A model reportedly routed through a gemini-3.7-flash Arena label generated a full interactive SVG product page with color variants, draggable controls and SVG download; Google has not confirmed its identity.

A poster argues that Gemini 4 Pro and Astra produce nearly identical results because the benchmark used is saturated at the top and can no longer separate models.

A user reading LuminaBench results says Gemini 4 and GPT-6 Astra are extremely close, but notes that Gemini drew the logo correctly.

On the same SVG prompt, Gemini 4 Pro and GPT-6 Astra both come out near perfect, though Astra's logo is slightly off, and the gap to other models is large.

A joking post says Gemini is no longer chosen by vibe coders and that only the release of Gemini 4 Pro can save Google CEO Sundar Pichai.

A user reran the same prompt in Arena battle mode and got identical outputs labeled muse spark 1.3 and kimi k3, raising suspicion that a model is simply being relabeled as Gemini.

Replying to LuminaBench, a user says Gemini has long been decent at SVGs but Gemini 4's output is clearly a step cleaner.

The author says "gemini 3.7 flash" in Arena, which was routing to Gemini 4 Pro, took about 20 minutes to draw a complex Xbox controller SVG, but the same result could not be reproduced the next day.
