    Is LongCat-Flash-Thinking or o4-mini better for production use?

    Both LongCat-Flash-Thinking and o4-mini are production API models. For cost-sensitive production traffic, LongCat-Flash-Thinking has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain. Many production stacks route cheap models for drafts and a frontier model for the hard turn, which is usually cheaper than sending everything to the expensive API.

    Can I switch between LongCat-Flash-Thinking and o4-mini in my app?

    Yes. Call LongCat-Flash-Thinking through Meituan and o4-mini through OpenAI 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.

    How accurate is this LongCat-Flash-Thinking vs o4-mini pricing data?

    List rates are the latest published Meituan API pricing and OpenAI API pricing, quoted per million tokens. Official rate sheets: https://anotherwrapper.com/tools/llm-pricing and https://developers.openai.com/api/docs/pricing. Prompt caching, batch APIs, and committed-use discounts can change the invoice. Benchmark scores are from official publications and independent evals, updated as new numbers land.

    LongCat-Flash-Thinking supports up to 128K output tokens per request, while o4-mini supports up to 100K output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.

    LongCat-Flash-Thinking runs at approximately 100 tokens/second while o4-mini runs at 115 tokens/second. o4-mini is faster in raw throughput. Throughput (tokens per second) and time-to-first-token are why two models with the same per-million-token price can still feel different in chat and agents.
