How hard is the SnowPro Specialty: Gen AI exam? +
It's less about generative AI theory and more about Snowflake's implementation. Snowflake Gen AI Functions is the largest domain at 38%, and Cortex function names and signatures change frequently. Governance is 29% and covers model access controls, cross-region inference and cost management, which builders often overlook. Snowpark Container Services and the Model Registry are also in scope, which catches SQL-only Cortex users.
What changed in GES-C02 compared with the earlier version? +
Snowflake updated the exam in March 2026. Document AI was dropped and replaced with document processing functions such as AI_PARSE_DOCUMENT. The current domains are Snowflake for Gen AI Overview 18%, Snowflake Gen AI Functions 38%, Snowflake Gen AI Governance 29% and Snowflake Document Processing 15%. Prep material built for the original version spends time on a product that's no longer tested.
What is the GES-C02 exam format? +
Snowflake has not published C02-specific figures that differ from the original version, which ran about 55 multiple-choice and multiple-select questions in 85 minutes. It's delivered online with a proctor or at a test center. Confirm the question count and time on Snowflake's exam page before booking, since specialty exams are updated more often than core ones.
What is the passing score for SnowPro Specialty: Gen AI? +
SnowPro exams are scored on a scaled range of 0 to 1000, and 750 is the commonly cited passing score for this exam. Because scaled scoring weights items differently, don't treat it as a simple 75% target. A weak Governance domain, at 29% of the exam, is the most common way to fall short.
What is the retake policy and how long is the certification valid? +
After a failed attempt you must wait seven days before retaking, and you can take the same exam up to four times in a 12-month period. Each attempt costs the full exam fee - Snowflake offers no free retakes. SnowPro certifications expire two years after they're awarded. Check Snowflake's exam page for the current fee.
How long should I prepare for the Gen AI specialty? +
With hands-on Cortex experience, 4 to 6 weeks of focused study is typical. Spend the most time on the current Cortex AI function lineup and syntax, governance and cost controls, and document processing with AI_PARSE_DOCUMENT. If you've only used Cortex from SQL, set aside time to try Snowpark Container Services and the Model Registry, since they're tested.
