OpenAI: GPT-6 Astra
This AI model, GPT-6 Astra, is developed by OpenAI and supports three input modalities: text, image, and file. It can handle large contexts of up to 1 million tokens and has the capability to reason and perform tasks that require tools. For those with a budget of $10 per million input tokens and $50 per million output tokens, this model may be worth considering. Its blended benchmark score of 95.1 suggests it performs well across various independent tests. However, its pricing is relatively high compared to other models on the market, which may limit its appeal for those with smaller budgets or lower usage requirements.
