Hy3 has a published SWE-bench Verified score of 78%. GLM-4.7-FlashX does not have that eval on this page yet.
GLM-4.7-FlashX supports a 203K token context window, while Hy3 supports 262K tokens. Hy3 offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Shared benchmark scores for GLM-4.7-FlashX and Hy3 are still limited. Check the comparison table for the evals each model has published. 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.
Both GLM-4.7-FlashX and Hy3 are production API models. For cost-sensitive production traffic, GLM-4.7-FlashX 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.

Official rate sheets: https://docs.z.ai/guides/overview/pricing and https://www.tencentcloud.com/document/product/1300/78937. 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.
GLM-4.7-FlashX supports up to an unspecified number of output tokens per request, while Hy3 supports up to an unspecified number of output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
Neither GLM-4.7-FlashX nor Hy3 has published throughput data on this page yet. 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.
