UnverifiedIn testing, the p99 latency per 160-millisecond tick was 147.4–147.5 milliseconds, with zero missed deadlines across three rounds totaling 84,000 session ticks measured.74% similarUnverifiedSome users found in tests with 3 coding prompts that completion times were consistently in the 30–45 second range, with 3.8 Flash being at most about 5 seconds faster.73% similarUnverifiedText-to-image generation is noticeably slow on the first run; in testing, the first image took 188 seconds, the second dropped to 103 seconds after the cache took effect, and the theoretical fastest speed can reach one image every 14 seconds.70% similar
