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.
The safest agent workflows default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
GPT-5.4 is the strongest answer here for agent workflows — pick it when quality of output matters more than the $2.50/1M/1M input you pay for it.
Codestral 25.01 handles the same job for about 79% less per token. Start here and only move up if the output is not good enough.
Gemini 3.1 Flash is the fastest of these for agent workflows — worth it when latency is what the reader notices, not the last few points of reasoning depth.
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 3.1 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.
Switch the scoring lens to see whether the agent workflows answer changes when cost, speed, or long-document depth leads the decision.

Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for agent workflows, what it is genuinely good at, and where we would steer you away from it.
The default answer for agent workflows — 90/100 on the coding axis, and the model we would start with unless the price below rules it out.
OpenAI's latest flagship with unique desktop-control capabilities — it can see your screen, click, and navigate apps via the API.
You need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks.
Best choice when you need a model that can operate software autonomously at the older GPT-5.4 price tier. For current premium coding quality, Claude Opus 4.7 leads.

Rounds out the shortlist for agent workflows at 78/100 on coding.
Lower-cost OpenAI model that keeps a solid balance of usefulness, speed, and affordability for everyday tasks.
Cost is your primary concern — Gemini 3.1 Flash offers more for less.
A decent budget OpenAI pick, but Gemini 3.1 Flash undercuts it on price with a larger context window.

For agent workflows, GPT-5.4 (OpenAI) is our pick. Best for agentic automation and desktop control workflows. It costs $2.5/1M input and $15/1M output tokens, with a 272K-token context window — enough headroom for all but the largest agent workflows jobs. GPT-5.2 Mini is the closest alternative if it doesn't fit your setup.
Because the work it is built for overlaps closely with agent workflows: building agents that browse the web and operate desktop software autonomously via the API and complex multi-step reasoning for financial modeling and decision analysis. Best choice when you need a model that can operate software autonomously at the older GPT-5.4 price tier. For current premium coding quality, Claude Opus 4.7 leads.
On a moderate month — 10M input and 2M output tokens — GPT-5.4 runs about $55.00 at list price, with no batch or caching discounts applied, so treat that as a ceiling. Gemini 3.1 Flash is the cheaper route at roughly $11.00 for the same volume, if agent workflows is high-volume enough for price to lead the decision.
Claude Opus 4.7 and GPT-5.5 now outperform it on current premium coding benchmarks. Smaller context window (272K) vs Gemini 3.1 Pro (2M) for research. Avoid it if you need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks. None of that rules it out for agent workflows on its own — but if one of those limits maps onto how you actually work, take the alternative on this page seriously rather than defaulting to the top pick.
Gemini 3.1 Flash at $0.5/1M input is the budget option here. Best cheap AI for broad day-to-day work — now with 1M context. Expect a quality step down on the hardest cases — the usual pattern is to route routine agent workflows volume to Gemini 3.1 Flash and keep GPT-5.4 for the work where a wrong answer is expensive.
Gemini 3.1 Flash, rated very fast against GPT-5.4's balanced. Speed matters most for interactive and high-volume work; if your agent workflows runs in the background, the slower and more capable model is usually the better trade.
