MAI-Code-1-Flash vs Claude Haiku 4.5
Microsoft picked this fight on purpose. When MAI-Code-1-Flash launched at Build 2026 on June 2, Microsoft framed it directly against Claude Haiku 4.5, claiming better price to performance across coding benchmarks in GitHub Copilot token-based billing. The numbers back the pricing half of that claim: $0.75 input and $4.50 output per million tokens versus Haiku at $0.80 and $4.00, with a $0.075 cached input rate and a claimed 60% reduction in tokens used on hard tasks, which matters more than the sticker price. Haiku counters with vision support, a mature track record in production, and Anthropic's tooling ecosystem. MAI-Code-1-Flash benchmarks are mostly Microsoft's own at launch, so treat the performance claims as provisional until independent results land.
