Personality & Tone

Tencent's first serious open-weights LLM

Tone: Direct and structured, similar to DeepSeek's chat tone -- compact answers in technical domains, reasonable Chinese-language polish, English noticeably less expressive than Claude or GPT.

Quirks: PRC content filters apply across the same set of regulated topics as DeepSeek and Qwen. Distribution via Yuanbao + WeChat + QQ means many Hy3 users in the wild are talking to it through chat-app surfaces rather than a developer console.

The Good and the Bad

What we like

  • +Open weights from a top-3 Chinese tech company is itself the headline -- Tencent had been a notable holdout while DeepSeek, Alibaba, Moonshot, MiniMap, and Z.ai shipped open-weight flagships through 2024-25
  • +Pricing is aggressive. ~1.2 RMB per million input tokens puts Hy3 in the same value bracket as DeepSeek V4-Flash and well below Western frontier models
  • +256K context is comfortable for retrieval-heavy and agentic workflows -- not as long as the 1M-context cohort (DeepSeek V4, Qwen 3.6-Plus, Gemini 2.5) but ample for most real workloads
  • +Distribution moat: Tencent already has Yuanbao + WeChat + QQ surfaces with hundreds of millions of MAUs. The model meets users where they already are, which matters in the Chinese market more than benchmarks
  • +Hy3 is the start of a multi-model family per Tencent's launch comms -- expect Pro / Flash / multimodal variants in coming months along the DeepSeek and Alibaba pattern

What could be better

  • Third-party benchmarks (Artificial Analysis, LMSYS, SWE-bench) are still spotty as of launch week -- treat Tencent's own benchmark claims with the usual self-reporting discount until independent runs corroborate
  • PRC content filters apply -- expect refusals or blandness on Tiananmen, Taiwan sovereignty, Xi Jinping, and other politically sensitive topics. Pattern matches DeepSeek and Qwen
  • Geo-availability: developers in EU / UK / Australia / Canada / South Korea / India should check local data-residency rules before deploying via API. Self-hosted open-weights deployment is the workaround
  • English-language polish lags Claude and GPT for nuanced writing tasks -- this is a coding / reasoning / Chinese-language pick first, prose-quality pick second

Pricing

API (Hy3 Preview)

~1.2 RMB/per 1M input tokens
  • Roughly $0.16 USD/M input at April 2026 exchange rates -- among the cheapest frontier-class APIs on the market
  • 295B total / 21B active MoE
  • 256K context window
  • Pricing position is closer to DeepSeek V4-Flash than to GPT-5.5 or Claude Opus 4.7

Self-hosted (open-source)

$0 + GPU costs
  • Open weights on Hugging Face (tencent/Hy3-preview)
  • Permits self-hosting and fine-tuning per the published license
  • 21B-active MoE means inference is feasible on multi-GPU consumer-tier setups for testing; production deployments still want H100/H200

System Requirements

Hardware needed to self-host. Min = smallest viable setup (usually heavy quantization). Max = full-precision / production-grade.

Known Issues

  • Hy3 Preview was released 2026-04-23 -- this is preview-stage, not GA. Expect rough edges around tokenizer behavior on rare scripts, occasional spec-compliance gaps in API responses, and Tencent quota tightening as adoption ramps. Track Tencent's GitHub + HF repo for stable-version cuts before depending on it in productionSource: Caixin Global, Pandaily, HuggingFace tencent/Hy3-preview · 2026-04-23
  • Pricing in RMB is the published number -- USD pricing depends on FX and may move. ~1.2 RMB/M input ≈ $0.16 USD at April 2026 rates. Output token pricing is published separately; check api docs before forecasting costSource: Caixin Global, Tencent product page · 2026-04
  • PRC content filtering applies. Hy3 declines to engage on Tiananmen Square, Taiwan sovereignty, and other regulated topics. Same operating reality as DeepSeek, Qwen, Kimi, GLM -- if your use case needs unfiltered geopolitics, choose a Western frontier model or a community-tuned open-weights variantSource: Pattern from DeepSeek/Qwen; Hy3 follows the same regulatory regime · 2026-04

Best for

Chinese-market builders, multilingual products that need strong CN performance, and cost-sensitive developers who want frontier-class quality at sub-DeepSeek pricing. Also anyone watching the open-weights field who wants Tencent's distribution-backed entry on the bench.

Not for

English-first creative writing (Claude or GPT-5.5 are stronger), use cases that touch Chinese-government-sensitive topics, or teams that need a fully proven track record of third-party benchmark verification. As preview-stage software it is genuinely 'preview.'

Our Verdict

Hy3 is Tencent finally entering the open-weights race with a serious model and aggressive pricing. The 295B / 21B-active MoE design is aligned with what Alibaba and DeepSeek have shown works at scale, and the ~1.2 RMB/M-token list price puts Hy3 in real competition with DeepSeek V4-Flash for the cost-per-token crown. Distribution through Yuanbao + WeChat + QQ is a structural advantage Western developers tend to under-weight. Caveats: it's preview-stage, third-party benchmarks are still incoming, PRC content filters apply. For a US/EU developer comparison-shopping a cheap frontier-class API right now, DeepSeek V4-Flash is still the safer first stop -- but Hy3 deserves a spot on the bench, especially if Chinese market reach matters.
