What to know about Hy3
AI-compiled from linked model documentation. This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026.
How can you access Hy3?
The catalog documents API and Open weights access for Hy3. Source 1 · Source 2
As of the catalog check, this version was listed as available. Source
For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription.
Open weights means the model weights are distributed for use under their stated terms. It does not establish a hosted API, an open-source license, or a hardware requirement. This record documents API access separately.
Which Hy3 does this page describe?
Hy3 is a model record from Tencent in the Hy3 family. Source
The recorded model identifier or checkpoint is Hy3. Use that exact identifier when checking documentation or a provider listing. Source
What are Hy3's context and output limits?
The documented context window is 256,000 tokens. Source
The documented maximum input is 192,000 tokens. Source
The documented maximum output is 128,000 tokens. Source
Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity.
What can Hy3 receive and generate?
Documented inputs: text. Source
Documented outputs: text. Source
Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation.
What license is recorded for Hy3?
The recorded license label is apache-2.0. Source
Read the linked license and associated use terms for this exact version before redistribution, commercial deployment or fine-tuning. A label alone does not establish every permission, restriction or obligation, and it does not determine the terms of a separate hosted service.
What is documented about the Hy3 checkpoint?
This evidence refers to tencent/Hy3 at recorded revision a960ebc3da325ba167f069f76c41eb62c9280d22, checked October 23, 2026. Repository metadata
Safetensors metadata records 298,786,155,776 stored parameters. This is a stored-weight count, not necessarily the number activated per token, a download size or a GPU-memory requirement. Repository metadata
Recorded architecture class: HYV3ForCausalLM. Repository metadata
Repository task tag: text-generation. A task tag identifies a distribution category; it does not measure performance on that task. Repository metadata
Listed library: transformers. Check that library's version and model support before loading the weights. Repository metadata
Repository access gate: false. This records the repository's gate setting when checked; licensing and use terms still apply. Repository metadata
What the configuration file says
The pinned config.json contains these values. Pinned configuration
max_position_embeddings- 262,144
torch_dtype- bfloat16
num_attention_heads- 64
num_key_value_heads- 8
num_hidden_layers- 80
hidden_size- 4,096
Configuration values describe the checkpoint and its implementation. In particular, max_position_embeddings, sliding_window and rope_scaling do not independently establish an API context limit, tested usable length or hardware requirement. Runtime, quantization, cache, batch size and input length affect deployment behavior.

A missing value remains unknown. Input limits, output limits and the total context window are separate measurements.

Read this with the numbers.
Official publisher weight listing; availability refers to this distribution, not a guaranteed hosted API. Base, SFT and research variants are identified by their exact published names. Official quantization/runtime variants are retained as aliases. Official context/input/output labels use K/M; numeric values use decimal display normalization. Tencent-hosted third-party models are excluded from this publisher inventory. Publisher repository evidence (2026-10-23): Publisher task label: text-generation. Published architecture metadata: HYV3ForCausalLM. Repository library label: transformers. Published safetensors metadata counts 298,786,155,776 stored parameters; this is not an active-parameter count for mixture-of-experts models. Published configuration: max_position_embeddings=262144; dtype=bfloat16; 80 hidden layers. Checkpoint configuration is not a verified hosted serving limit; context and output limits remain separate documented fields.
