Performance Summary

Morph V3 Large, created on July 7, 2025, is designed for complex code edits, boasting a high throughput of approximately 4,500 tokens/sec with 98% accuracy for precise code transformations. The model consistently ranks among the fastest available, demonstrating exceptional speed performance. Price data is currently unavailable, suggesting it may be offered under a free tier or its cost structure is not publicly disclosed. However, a significant concern is its extremely low reliability, experiencing frequent technical failures that severely impact usability, with a 0% success rate across benchmarks. This unreliability is evident in its benchmark performance, where it achieved 0.0% accuracy in the Coding (Baseline) benchmark, with a duration of 133498ms. While its intended purpose of high-accuracy code transformations and impressive speed are notable strengths, the critical lack of reliability renders these benefits largely inaccessible. The model's inability to consistently provide usable responses is a major weakness that needs immediate attention.
