Open-Source vs Frontier Models: The Production Decision
Llama, Mistral, Qwen are good enough for many production tasks now. The decision isn't 'closed wins on capability' anymore — it's 'closed wins on convenience, open wins on control.'

The premise
Open-source models have caught up on many tasks; the decision now hinges on operational concerns (cost, control, privacy) more than raw capability.
What AI does well here
- Use open-source for: data sovereignty (HIPAA, GDPR, on-prem requirements), high token volume cost optimization, fine-tuning on proprietary data
- Use frontier closed for: cutting-edge capability needs, low-volume use, hosted-managed simplicity
- Run benchmarks on YOUR use case — generic 'closed beats open' or 'open caught up' both miss the workload-specific picture
- Plan for the operational burden of self-hosting (infra, monitoring, updates, security)
What AI cannot do
- Get frontier capabilities at zero cost — open-source has hidden infra costs
- Avoid the operational burden of self-hosting once committed
- Predict the open vs closed gap 12 months out
