WE TESTED MINIMAX M2.7 AGAINST CLAUDE OPUS 4.6

MiniMax M2.7 offers 90% of the quality of Claude Opus 4.6 at just 7% of the cost, excelling in bug detection but less thorough in fixes. It performs better in floating-point calculations and matches Claude in vulnerability detection, though Claude provides more comprehensive solutions. With rates of $0.30/$1.20 per million tokens versus Claude's $5/$25, MiniMax is a cost-effective tool that bridges the gap between open-weight and frontier models.

TOKEN MYTH

Token spend doesn't matter if tasks aren't being completed. The total tokens consumed per task varies across models. A company that charges double for tokens could still be the cheaper option if its models return the right answer in fewer turns. Instead of using token spend as a KPI, companies should measure cost per successfully completed task.
