ChatGPT JEE Advanced score
Quick answer
On official JEE Advanced 2026 papers, GPT 6 Astra scored 356/360 and GPT 5.5 scored 351/360. On JEE Advanced 2025, GPT 6 Astra scored 352/360 and GPT 5.6 Luna scored 319/360. All runs were blind: the printed question only, then the IIT key.
“ChatGPT” here means the OpenAI models we actually called — GPT 6 Astra, GPT 5.5, and GPT 5.6 Luna — not a consumer chat wrapper. GPT 5.5 shipped on 23 April 2026. JEE Advanced 2026 was held on 17 May 2026, 24 days later, so that paper was not in the GPT 5.5 training cutoff.

Frequently asked questions
What is ChatGPT’s JEE Advanced score?
On official JEE Advanced 2026 papers, OpenAI models scored GPT 6 Astra 356/360, GPT 5.5 351/360. On JEE Advanced 2025 they scored GPT 6 Astra 352/360, GPT 5.6 Luna 319/360.
Can ChatGPT solve JEE?
On JEE Advanced 2026, GPT 6 Astra scored 356/360 and GPT 5.5 scored 351/360. Both sat the official English papers blind. That is a near-complete solve of JEE Advanced, not JEE Main.
Could ChatGPT have memorised JEE Advanced 2026?
Unlikely for GPT 5.5. OpenAI released it on 23 April 2026. JEE Advanced 2026 was held on 17 May 2026 — 24 days later — so the 2026 paper did not exist when that model shipped.
Which JEE Advanced 2026 questions did GPT 5.5 miss?
GPT 5.5 missed Paper 2 Mathematics question 4 (returned letter A with no written 1/3) and Paper 2 Chemistry question 9 (added an extra option D). Full traces are on the GPT 5.5 question log.
Did ChatGPT see the official answers?
No. Prompts included only the printed question and its type. Official keys were used only for scoring.
