AI model comparison
Compare recorded price, context, output limits, speed, latency, capabilities, and input/output support. Every missing value stays visible, and unsourced benchmarks are excluded.
This Claude Haiku 3.5 vs GPT-5.5 comparison is designed for teams choosing between two production model records, not for declaring a universal winner. Claude Haiku 3.5 by Anthropic currently records 200K context, 8.2K maximum output, $0.80 input per 1M tokens, $4.00 output per 1M tokens. GPT-5.5 by OpenAI records 1.1M context, 128K maximum output, $5.00 input per 1M tokens, $30.00 output per 1M tokens. The tables below separate documented capabilities, commercial limits, directory measurements, and source-linked benchmark evidence so you can see where the data is complete and where independent testing is still required.

Workload guidance
Claude Haiku 3.5 currently leads on lower recorded input price, lower recorded output price. GPT-5.5 currently leads on larger context, larger maximum output. Choose according to the constraints that matter to your workload, then run the same representative prompts against both models before making a production commitment. Neither the larger number nor the lower price is automatically the better choice: prompt quality, tool reliability, modality support, rate limits, data policy, and provider implementation can change the result. Use this page to build a shortlist, confirm current terms in the linked sources, and validate quality, latency, and cost with your own traffic.
Provenance
Prices and hosted performance can change. SyncDev records source references and clearly separates documented specifications from measured values; confirm commercial terms with the provider before deployment.
