GPT-5.4 is the best AI for agent workflows when reliability matters because multi-step systems break faster on mediocre reasoning than on slightly higher token cost.
Use GPT-5.4 for higher-stakes agents and GPT-5.2 Mini for lower-cost automations where some oversight still exists in the loop.
Agent workflows magnify model mistakes, and GPT-5.4 is the safest option here for multi-step reliability and coding-heavy task execution.
GPT-5.4 is the strongest model for reliable agent behavior in this directory.
GPT-5.2 Mini is the better lower-cost option when humans still supervise more of the flow.
Gemini 2.5 Flash is attractive for speed and price, but it is not the safest agent default for harder tasks.
Use GPT-5.4 for tool-using agents where bad decisions are expensive.
Use GPT-5.2 Mini for internal automations and lower-cost agent loops.
Use Codestral when the agent is tightly focused on code generation and edits.
