OpenAI has made available GPT-4o Mini – a smaller and cheaper version of its GPT-4o generative large language model – via its cloud.in that it's multimodal – it can handle more than just the written word – and has a context window of 128,000 tokens and was trained on materials dated up to October 2023. The Mini version can emit up to 16,000 tokens of output.$5 and $15 per million input and output tokens, respectively, the Mini edition costs 15 and 60 cents.
Furthermore, OpenAI claimed GPT-4o Mini is ahead of comparable LLMs in benchmarks. Compared to Google's lighter-weight Gemini Flash and Anthropic's Claude Haiku, Mini was usually between five and 15 percent more accurate in tests such as. In two outliers it was nearly twice as accurate as the competition, and in another a little worse than Gemini Flash but still ahead of Claude Haiku, allegedly.
Competition between OpenAI and Anthropic has a personal edge, as the latter was co-founded and built in part by executives and engineers from the former. At 82 percent accuracy in MMLU and a cost of 15 cents per million tokens, GPT-4o Mini is mostly ahead of the pack. However, Willison noted the LMSYS Chatbot Arenaprovides a more realistic evaluation of LLM quality because actual humans are asked to compare outputs and choose which is better – a brute-force but effective way of ranking different models.
