GPT-OSS-120B PERFORMANCE VARIES DRAMATICALLY BY PROVIDER

Summary from the TLDR AI newsletter

Artificial Analysis benchmarked OpenAI's gpt-oss-120B across 11 API providers and found striking performance differences despite hosting the same model. AIME math scores ranged from 78.3% on Azure to 93.3% on Cerebras — a 15-point gap that suggests provider infrastructure significantly impacts model capabilities. The major cloud providers (Azure, Amazon Bedrock, and Nebius Base) consistently lag behind smaller, specialized AI inference startups like Cerebras, Groq, and Fireworks.
