What to know about MiniCPM-1B-sft-bf16
AI-compiled from linked model documentation. This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026.
Which MiniCPM-1B-sft-bf16 does this page describe?
MiniCPM-1B-sft-bf16 is a model record from OpenBMB in the MiniCPM family. Source
The recorded model identifier or checkpoint is MiniCPM-1B-sft-bf16. Use that exact identifier when checking documentation or a provider listing. Source
How can you access MiniCPM-1B-sft-bf16?
The catalog documents Open weights access for MiniCPM-1B-sft-bf16. Source
As of the catalog check, this version was listed as available. Source
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.
What dates are documented for MiniCPM-1B-sft-bf16?
Release date: April 11, 2024. Source This is a release milestone, not a knowledge or training cutoff. The source labels this “Official announcement links the exact MiniCPM-1B-sft-bf16 release.”
Neither a knowledge cutoff nor a training-data cutoff is established here. A release date, repository upload or filename cannot supply those missing dates.
What can MiniCPM-1B-sft-bf16 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 MiniCPM-1B-sft-bf16?
The recorded license label is General Model License (model weights); Apache 2.0 (code). 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 distinguishes MiniCPM-1B-sft-bf16?
These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results.
- Non-embedding parameters
- 1.2 billion, excluding embedding parameters. Source
- Released weight precision
- The pinned exact 1B checkpoint configuration declares bfloat16 weights. Source
- Tokenizer vocabulary
- The paper specifies a 73,440-token vocabulary for the MiniCPM-1.2B architecture used by the nominal 1B release. Source
- Training stages
- The MiniCPM recipe separates stable training, decay training and supervised fine-tuning. Source
What is documented about the MiniCPM-1B-sft-bf16 checkpoint?
This evidence refers to openbmb/MiniCPM-1B-sft-bf16 at recorded revision 85252935bfc9acb3ee93dcea4b793fb87a0b43e8, checked October 23, 2026. Repository metadata
Recorded architecture class: MiniCPMForCausalLM. 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 language labels: en and zh. These labels are not independent evaluations of language quality. 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- 4,096
torch_dtype- bfloat16
num_attention_heads- 24
num_key_value_heads- 8
num_hidden_layers- 52
hidden_size- 1,536
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.

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. Publisher repository evidence (2026-10-23): Publisher task label: text-generation. Published architecture metadata: MiniCPMForCausalLM. Repository library label: transformers. Model-card language labels: en, zh; these labels are not evaluated proficiency scores. Published configuration: max_position_embeddings=4096; dtype=bfloat16; 52 hidden layers. Checkpoint configuration is not a verified hosted serving limit; context and output limits remain separate documented fields.
