Choose Claude Haiku 5.5 if…
- you need classification and extraction
- you need routing tiers
- you need latency-sensitive paths
Ten cents a million and, per the people using it, smarter than the other ten-cent model; mind the 100K cliff.
Caveats: Price jumps five-fold above 100K input tokens, which commenters call an absurdly low cutoff for agent runs.
Choose Grok 4.7 if…
- you need x-integrated products
Mid-table on the index at a frontier price, with a smaller context window than everyone above it.
Caveats: 500K context is the smallest in the table. Listed by Artificial Analysis under the creator's current corporate name.
What practitioners say
Claude Haiku 5.5: The thread had over a thousand points in a day; the recurring reports are near-perfect structured classification in production and 'noticeably smarter than GPT-6 Luna', against complaints about the 100K pricing tier.

Scores come from the Models at Work leaderboard: Score is 0 to 100: 50% independent evals normalised within this table, 20% price-performance, 15% practitioner sentiment from Signals and community threads, 15% operational fit (context, speed, availability, open weights). Models within three points are a tie in practice. Vendor-published figures are labelled as such and never counted as independent. Prices are vendor list prices where published; blended figures assume three input tokens per output token.
