    AI observability can cost more than it should. We ran the numbers: same scale, same workload, four tools. At moderate production load, Logfire is up to 40x less expensive than the alternatives. Spans-based pricing. No proprietary units. AI native and full-stack observability in
    table showing the comparison between Logfire, Arize (AX) Phoenix, Langfuse, and Langsmith (Langchain). The comparison shows Logfire is between 8 times and 100 times cheaper than the shown alternatives for 5 users and 50M spans load per month.

    Built a model battle playground for @nebiustf models with 3 modes: Code, Design, and Game. I put GLM-5.2 and Kimi K-2.7 Code to test on the same task. Rules: each model builds, reviews what it built, and gets 3 attempts to fix its own errors. The prompt was simple, but the
