Reflection releases Beam's open weights and Mirror coding agent, giving developers more deployment choice alongside substantial hardware requirements. Also: China's technology-export consultation and…
It doesn't establish how reliably the model will use every part of that material, or how economical a heavily loaded service will be.
Beam has 501 billion parameters in total, with about 23 billion active for each token.
A smaller active portion means the full parameter count isn't used for every token, but the full model still has to be accommodated by the serving setup.
That's why the 23 billion figure and the hardware recommendation can both be true.
Hugging Face's launch documentation puts the compressed NVF P4 weights at roughly 280 gigabytes.
Its recommendation of 4B200 GPUs is for practical serving, including capacity for context and concurrent requests.
Having enough space to hold the weights is only part of operating a useful service.
Consider the difference between one developer trying a prompt and an organization handling several long requests at once.
A large advertised context window doesn't remove the need to plan for how people actually use it.
The attraction of self-hosting is control over where inference runs, where the model processes a request and generates its response.
For an organization that needs that control, downloadable weights create an option that access to a remote service alone can't provide.
The organization also takes on the work of keeping the model available on suitable infrastructure.
It leaves the developer dependent on a service which may be a perfectly sensible trade when their main task is building an application.
