Inception: Mercury 2
Inception: Mercury 2 is designed to handle text-based tasks with an expansive context length of 128,000 tokens and supports reasoning and tools integration for more complex problem-solving. While it does not offer structured output capabilities, its performance in benchmarks stands at 41.2 across independent evaluations. This model might be a good fit for those requiring extensive text handling and flexible tool use without the need for structured outputs. Its pricing at $0.25 per million input tokens and $0.75 per million output tokens makes it relatively affordable, especially considering its benchmark score of 41.2; however, users should weigh this against their specific needs as structured output support is lacking.
