Verdict

When to choose each

Claude Opus 5

Where it leads

  • Batch pricing, $2.50 input and $12.50 output per 1M tokens

Best for

  • Complex agentic coding and enterprise work as the general-purpose default before reaching for Fable 5.1
  • Latency-sensitive work that can justify Fast mode pricing

Watch out for

  • Fast mode pricing applies to the whole request, including above 200K input tokens, so it doubles the effective rate rather than adding a surcharge
  • Cache reads are $0.50 per million (the standard 0.1x), five times Fable 5.1’s $0.25, even though Opus 5 is the cheaper model on base tokens. A cache-heavy agent loop can invert the expected cost ordering between the two.

LongCat-2.5

Where it leads

  • Lower input and output prices, $0.30 and $1.20 vs $5 and $25 per 1M tokens
  • Longer responses, up to 262,144 vs 128,000 output tokens
  • Accepts video input
  • Cheaper cached input, $0.006 vs $0.50 per 1M tokens

Best for

  • Coding agents working through whole projects in Claude Code, Codex or similar harnesses
  • Visual coding and design work that mixes screenshots or screen recordings with code

Watch out for

  • The recorded rates are a limited-time discount: Meituan publishes no list price and no end date
  • API only: no weights had been published when this record was made
  • Released on 2 November 2026, so no independent benchmark score is recorded here yet
