- The cheapest OpenRouter route charges $1.75 input / $14.00 output.
Sources & methodology
GPT-5.2 has no arena.ai Agents result yet, so on our leaderboard it is listed after models that do.
- arena.ai Agents — agent task success rate, 95% interval, sessions and rank (via the public Hugging Face dataset, CC BY 4.0).
- LMArena — Arena score (Text leaderboard with style control, the same view arena.ai shows by default), 95% confidence interval, votes and rank.
- Artificial Analysis — Intelligence / Coding Index, output speed and latency (medians).
- OpenRouter — Route prices, context length and listing date.
Arena scores use the Bradley-Terry model (not Elo); ± is the half-width of the 95% confidence interval. Latency figures are Artificial Analysis medians; for reasoning models, time to first token and to first answer include the thinking phase. Data syncs daily at 14:20 (UTC+8).
Limits: Arena scores come from anonymous users voting on chats, so they reflect conversational preference rather than agent or coding benchmarks; with few votes the interval is wide and ranks move. Prices and speeds change as providers update them.
FAQ
What rank is GPT-5.2 right now?
GPT-5.2 is #61 on our leaderboard of 69 scored models (Arena score 1437.2); its raw LMArena rank is #101.
What does GPT-5.2 cost via API?
Input $1.75 / output $14.00 per 1M tokens (official API list price; the OpenRouter quote when no official price is available). At a typical 3:1 input-to-output ratio, the blended cost is about $4.81 per 1M tokens.
How close is GPT-5.2 to the models ranked next to it?
It is 3.4 points behind MiniMax M3 (1440.6) and 0.1 points ahead of Qwen3.8 27B (1437.1); gaps smaller than the confidence interval (±3.6) are not significant.
Is GPT-5.2 open source? Can it be self-hosted?
GPT-5.2 is a closed model, available only via official APIs or hosted services.
What is the context length of GPT-5.2?
400K (400,000 tokens, as listed on OpenRouter).
GPT-5.2 vs MiniMax M3: which is better?
On the LMArena Text leaderboard GPT-5.2 scores 1437.2 and MiniMax M3 scores 1440.6 (a 3.4-point gap, within the confidence interval, so not significant). On price, GPT-5.2 costs $14.00 and MiniMax M3 $1.20 per 1M output tokens.
Is there a cheaper model close to GPT-5.2?
Yes: Kimi K2.5 scores 1449.9 on the Text leaderboard (GPT-5.2: 1437.2) and costs $3.00 per 1M output tokens, about 79% less than GPT-5.2 ($14.00).
Where does the GPT-5.2 data come from and how often is it updated?
Agent success rates come from the arena.ai Agents leaderboard (CC BY 4.0), Text scores from LMArena, intelligence and speed from Artificial Analysis, and prices and context from official list prices and OpenRouter. 17NAS syncs daily at 06:20 UTC; this page was last updated Oct 22, 2026.
