Agentic AI models need to use tools reliably, maintain context over long tasks, and self-correct without human intervention. Claude Opus 4.7 leads on autonomous coding agents (64.3% SWE-bench Pro). GPT-5.4 is the only model that can control a desktop via API. GPT-5.5 excels on Terminal-Bench for command-line agent workflows.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
Claude Opus 4.7 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Switch the scoring lens to see whether the top answer changes when you care more about cost, speed, or long-document work.
Anthropic / Premium / Apr 26, 2026
Best premium model for coding agents and high-stakes engineering work.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You need cheaper high-volume throughput, image generation, or a workflow that must stay inside OpenAI tooling.
The fastest way to see where the recommendation shifts when your priority changes.
64.3% on SWE-Bench Pro, ahead of GPT-5.5 and GPT-5.4 in current public comparisons
1M context window for large codebases and document-heavy workflows
Strong vision and agentic consistency improvements over Opus 4.6
Premium pricing is expensive for high-volume workloads
GPT-5.5 has stronger OpenAI ecosystem fit and faster Codex availability for some teams

Claude Opus 4.7 is the best for autonomous coding agents with a 64.3% SWE-Bench Pro score. GPT-5.4 is best when agents need to interact with desktop software. GPT-5.5 is the strongest for OpenAI-native Codex agent pipelines.
All frontier models (Claude, GPT-5.x, Gemini 3.1 Pro) support structured tool/function calling. Claude models are generally more reliable at following tool schemas without hallucinating parameters.
Yes — Llama 4 Maverick and DeepSeek V3 both support function calling and work well in open-source agent frameworks like LangGraph and AutoGen. Expect lower reliability than frontier closed models on complex multi-step tasks.
Meta: Llama 3.1 8B Instruct is the lower-cost option to start with when you still need useful output at scale.
GPT-5.5 is the better pick when response speed matters more than maximum reasoning depth.
Claude Opus 4.7 leads SWE-Bench Pro at 64.3% — the benchmark for autonomous coding agents.
GPT-5.4 is the only frontier model with real computer-use (desktop control) via the API.
GPT-5.5 scores 82.7% on Terminal-Bench and integrates natively with Codex agent pipelines.
Choose Claude Opus 4.7 when coding quality and autonomous PR/review loops matter most.
Choose GPT-5.4 when your agent needs to click, type, or navigate desktop software via API.
Choose Claude Sonnet 4.6 for cost-effective agentic coding at $3/1M input — 79.6% SWE-bench.
