Choosing an AI model is no longer a simple race to the top of a benchmark.
The Collider brings builders and engineering leaders together to examine the real trade-offs between open-source, closed-source, and open-weight models—from capacity planning and infrastructure to choosing the right capability for the work.

Roundtable
How do you choose the model that actually fits?
A moderated discussion grounded in engineering constraints, operating costs, and the work a model truly needs to do.

Session
You Don't Need Frontier AI for Everything
The collision
Capability, control, and capacity
01
Open, closed, or open-weight?
How licensing, access, control, and deployment options shape the right model strategy for a product or organization.
02
Capacity is a product decision
Why model selection also means planning infrastructure, latency, cost, reliability, and the teams needed to operate it.
03
Fit beats frontier
Where smaller or less complex models can deliver better practical outcomes than defaulting to frontier capability.
Who should join
For builders making real model choices
A practical event for people evaluating, integrating, or operating AI models and looking beyond leaderboard performance to the full engineering decision.
AI and software engineers
Technical founders and product leaders
Infrastructure, platform, and data teams
