The decision context
Open-weight models can expand hosting, customization, privacy, and infrastructure choices, but the term does not by itself define a software license, training-data disclosure, reproducibility, or an open-source system.
The deployed result includes a checkpoint, revision, tokenizer, prompt template, quantization, serving engine, hardware, safety layer, and operations process. Each should be pinned before comparing it with a hosted API.
Why it matters
- Deployment control can support data-boundary goals but transfers uptime and security work to the operator.
- Quantization and serving choices can change behavior enough to invalidate a borrowed benchmark.
- Different model families and even sizes within one family can use different terms or resource requirements.
Questions to answer before choosing
- What do the exact model license and acceptable-use terms permit?
- Who will patch the serving stack, monitor abuse, and schedule model upgrades?
- Which hardware, throughput, availability, and data-location requirements apply?
- How will the team compare a self-hosted system fairly with a managed endpoint?
A reviewable decision path
Each step should leave a record that another reviewer can inspect.
- 01
Review the exact license
Record the checkpoint, revision, license text, use restrictions, and distribution obligations.
- 02
Define the serving bill of materials
Pin tokenizer, quantization, runtime, container, hardware, prompt template, and safety layer.
- 03
Benchmark the deployment
Measure the served system, not an unrelated provider configuration.
- 04
Model total operations
Include capacity, observability, patching, abuse controls, backups, incident response, and staff time.
- 05
Plan replacement
Document how a new checkpoint is qualified, deployed, rolled back, and audited.
