OpenAI: GPT-6 Astra (batch)
The OpenAI GPT-6 Astra batch model is designed for a wide range of applications, handling text, image, and file input modalities with a maximum context length of 1,050,000 tokens. It supports the use of tools and reasoning capabilities, but does not provide structured output. This model is a strong contender to consider for those who value high performance and flexibility. With a blended benchmark score of 95.1 across three independent benchmarks, it demonstrates exceptional accuracy in various tasks. Its pricing plan, which charges $5.0 per million input tokens and $25.0 per million output tokens, may be a factor for some users; those seeking the best balance between cost and performance may find this model worth shortlisting.
