We ran a cheap open model against Sonnet 5.5 on 100 real conversations from a client’s chatbot. GLM 5.3 Flash passed 89 to Sonnet’s 90, and it cost 90% less and ran twice as fast.

I sat down with my co-founder Jonathan on the week AI agents got a regulator and personal agents went mainstream. The FTC looking into OpenAI and Anthropic, Cloudflare and Databricks launching their own decision models, Claude Code mods vs Codex plugins, the OpenAI Dev Day 2026 recap, and why building a plugin might be the best distribution move you can make right now.

If you’re an AI builder or a tech exec who’s still paying to -model prices for every chat, you need to watch this.

Hosted by Robert Ta and Jonathan McCoy, co-founders of Clarity, reporting from the front lines of building an AI company.
