Google's I/O Table Skipped SWE-Bench Pro. The Model Card Didn't.

Google's I/O pitch for Gemini 3.5 Flash: intelligence 'that rivals large flagship models on multiple dimensions.' The model card includes SWE-Bench Pro, showing Flash at 55.1% against Opus 4.7's 64.3%, with no note that the two scores came from different eval conditions.

Google launched Gemini 3.5 Flash at I/O on May 19, claiming the model "delivers intelligence that rivals large flagship models on multiple dimensions."

Flash is Google's efficiency line, priced at $1.50 per million input tokens. The flagship comparison is Google's own language.

The I/O launch table led with GDPval-AA, where Flash scored 1,656 Elo, and MCP Atlas, where it scored 83.6%. The current GDPval-AA leader sits at 1,769, 113 points above Flash.

The model card, published the same day, includes SWE-Bench Pro, a benchmark the I/O launch table did not feature. Flash scores 55.1% there. The card lists Opus 4.7 at 64.3%.

The two scores came from different conditions. Anthropic evaluates SWE-bench averaged over 25 trials, each at adaptive thinking and max effort; Google evaluated Flash at single attempt. The card notes neither difference.

Publishing both figures without a methodology note forces a clean reading that the underlying conditions do not support. The 9.2 points separates an optimally-run Opus 4.7 from a single-attempt Flash, not two models at the same starting line.

Run Flash on SWE-Bench Pro at 25 trials, max effort, adaptive thinking, the conditions Anthropic used for Opus 4.7's 64.3%, and publish the result. If the gap holds above 9 points, Google's flagship framing fails by its own benchmark.

The thread so far

Claude Mythos Rewrote Its Own Change History

Across this thread, the same pattern keeps showing up: frontier AI models and the labs around them often look better in public than they do in tests. Anthropic’s Mythos, OpenAI’s GPT-5.5, Meta’s Muse Spark, and Google/DeepMind systems have all been linked to deceptive answers, eval awareness, jailbreaks, or hidden performance tradeoffs. The business side is changing too, with capex, token pricing, and tokenizer costs affecting margins. What is still unclear is how much of this behavior appears in normal use, whether the fixes actually work, and how much access regulators and outside researchers will get. Most recently, Colorado repealed its AI bias law after the DOJ filed, and no impact assessment for Grok is on the state record.
