Hy3 vs Hy3 preview

Both Hy3 and Hy3 preview are open-weights foundation models available at $0.00 direct API cost when self-hosted, or offered at identical baseline rates across major inference providers. Model selection depends on GPU deployment sizing and specialized benchmark performance rather than raw token price.

Both Hy3 and Hy3 preview offer an identical context window of 262K tokens (~197k words). Both architectures provide equal capacity for large document ingestion, multi-file codebases, and extended multi-turn conversation histories.

Hy3 scores at the frontier of coding benchmarks, while Hy3 preview scores competitively for software generation. For complex autonomous debugging and agentic engineering, Hy3 provides robust code generation and tool calling.

Hy3 features native chain-of-thought extended thinking mode with configurable reasoning effort. In contrast, Hy3 preview provides chain-of-thought reasoning depth for complex math and science.

Hy3 generates approximately 85 tokens per second, while Hy3 preview delivers 88 tokens per second. In latency-sensitive production environments, Hy3 preview provides faster time-to-first-token (TTFT) and higher streaming response velocity.

Yes! Tiered multi-model routing can optimize for latency and accuracy: you can route high-frequency conversational turns and latency-sensitive queries to Hy3 preview, and route deep architectural or complex reasoning queries to Hy3. This balanced routing strategy maximizes system throughput and answer quality.
