Tencent is distributing Hy3 through three primary tools :
Developers can also access Hy3 via API through OpenRouter (priced at approximately $0.1288 per million input tokens and $0.5336 per million output tokens) , and the model weights are published under the Apache 2.0 license on Hugging Face and ModelScope .
| Property | Value |
|---|---|
| Architecture | Mixture-of-Experts (MoE) — 192 experts, top-8 activated |
| Total parameters | 295 billion |
| Active parameters per token | 21 billion (+ 3.8B MTP speculative layer) |
| Context length | 256K tokens |
| License | Apache 2.0 (commercially friendly) |
| Release date | July 6, 2026 (preview: April 23, 2026) |
Hy3 is a hybrid fast-and-slow-thinking reasoning model designed for complex reasoning, instruction-following, coding, and AI-agent workflows. Tencent says it performs comparably to flagship models with 2–5× more parameters across reasoning and instruction benchmarks . The Hy3 preview debuted with hallucination rates at 12.5% and commonsense errors at 25.4%; the final July release dropped those figures to 5.4% and 12.7% respectively, after integrating feedback from over 50 internal Tencent teams .
Usage data reported by Tencent and confirmed by multiple sources shows remarkable early adoption :
Note: As of the August 5 announcement, Hy3 ranked third behind DeepSeek V4 Flash and Xiaomi MiMo-V2.5 on OpenRouter's weekly token usage ranking .
This global expansion is Tencent's first major overseas AI push since hiring former OpenAI researcher Yao Shunyu earlier in 2026 . Multiple reports frame the Hy3 international rollout as Tencent's most aggressive competitive move against Western AI leaders, signaling a strategic shift from a China-focused AI strategy to a global go-to-market posture . By combining open-source accessibility, enterprise tool integration, aggressive pricing (undercutting OpenAI and Anthropic), and a free-trial period on WorkBuddy, Tencent is aiming to capture developer and enterprise market share outside China — a direct response to the talent infusion and strategic direction set by Yao Shunyu's leadership .
Hy3 scored 78% on SWE-bench Verified and 90.4% on GPQA Diamond . Tencent reports a 90% task resolution rate on internal agent benchmarks . These figures place Hy3 competitively among open-weight reasoning models, though independent verification remains limited.
| Access Point | Pricing |
|---|---|
| WorkBuddy | Free until August 31, 2026 (Pacific Time) |
| OpenRouter API | ~$0.1288 / M input tokens, ~$0.5336 / M output tokens |
| Official Tencent API | ~1 RMB / M input, ~4 RMB / M output (about $0.15 / $0.59 USD) |
| Self-hosted | Minimum 8× GPU tensor parallel (H20-3e or H200-class) |
Tencent's Hy3 global rollout matters because it combines:
The model's primary strengths are in agentic workflows and coding tasks, areas where it has shown strong developer adoption. Its weaknesses include mid-tier performance on some general benchmarks and the need for high-end GPU clusters for self-hosting .
