Models with clear service provenance.
SENDFU-developed fine-tuned models sit alongside authorized open-weight services operated by SENDFU. Every record identifies the actual model-control and delivery relationship—not a blanket ownership claim.
Two operating relationships.
One separately identified SENDFU-developed fine-tuned model and 20 SENDFU-hosted authorized open-weight services are available through Controlled Access.
SENDFU-developed fine-tuned model
A separate SENDFU model identity with a controlled fine-tuning artifact, authorized training materials, technical review, and SENDFU-operated deployment.
SENDFU-hosted open-weight services
Authorized open-weight models deployed in SENDFU-managed AIDC infrastructure, with SENDFU runtime operation and delivery controls.
Controlled Access
Access is limited to approved partners, reviewers, and eligible enterprise users. It is not a public self-serve availability claim.
SENDFU-developed model
This label is reserved for a separate model variant with a SENDFU-controlled fine-tuning artifact or checkpoint—not a prompt wrapper or relabeled upstream route.
sendfu-mature-rp-01
A separately identified SENDFU-developed fine-tuned model for mature-audience fictional roleplay, character-driven dialogue, and long-form narrative work. Access is limited to approved partners, reviewers, and eligible enterprise use cases, subject to age, regional, account, and content-policy controls.
View model card21-model controlled-access catalog
Catalog records are available through the public read-only metadata API. A catalog record does not create public inference access, model entitlement, or production credentials. Controlled Access is issued only through the applicable approval, credential, and service process.
How records are classified
Each record separates model origin, serving relationship, and access status; none of these fields transfers ownership of third-party base-model weights.
Fine-tuning control
sendfu_developed is used only when SENDFU controls a separately identifiable fine-tuning artifact and has the relevant development rights. Other catalog services are identified as authorized third-party model services.
Serving control
sendfu_hosted is used when the model is lawfully deployed in SENDFU-managed AIDC infrastructure and SENDFU controls its serving runtime and operations.
Approved delivery
controlled_access means credentials are issued only after approval and applicable service terms. Public Preview responses are not model inference access.
