- Who it helps
- Developers and organizations evaluating a new model provider.
- Availability
- The October 6 announcement offers an API preview and says weights are planned for later October. Downloadable weights were not verified in this run.
What is available
API availability lets a team evaluate the hosted service. A future local deployment also requires released artifacts, compatible infrastructure and an applicable license.
A useful first check
For a preview evaluation, use a small fixed task and record quality, response time and usage. Wait for the actual weight release before planning a reproducible local installation.
