Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.

    Is Gemini 2.5 Pro or LongCat-Flash-Chat better for production use?

    Both Gemini 2.5 Pro and LongCat-Flash-Chat are production API models. For cost-sensitive production traffic, LongCat-Flash-Chat has better economics on the blended 1M-in + 1M-out scale.

    Yes. Call Gemini 2.5 Pro through Google and LongCat-Flash-Chat through Meituan with separate API keys, or through a gateway that already wraps both. Keep prompts in tokens, not characters, when you estimate the invoice. AnotherWrapper templates can swap providers without rewriting auth and billing.

    List rates are the latest published Gemini API pricing and Meituan API pricing, quoted per million tokens. Official rate sheets: https://ai.google.dev/gemini-api/docs/pricing and https://anotherwrapper.com/tools/llm-pricing. Prompt caching, batch APIs, and committed-use discounts can change the invoice.

    Gemini 2.5 Pro supports up to 66K output tokens per request, while LongCat-Flash-Chat supports up to 128K output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
