Claude Code Fastest Agent, But Costs 3x More
Composio ran the same model, DeepSeek V4 Flash, through four different agent frameworks and found the wrapper matters almost as much as the model inside it. The company tested Claude Code, Codex, OpenCode, and Oh My Pi on 30 tasks that touched Gmail, GitHub, Slack, and Notion, the kind of work an AI agent is actually hired to do. Same model, same tasks, four different price tags and four different clocks.
Claude Code finished jobs fastest, at 122 seconds on average, using fewer tool calls and less output than its rivals. That speed came at a cost: it was also the most expensive option in the test, running nearly three times the price of the cheapest alternative. OpenCode undercut everyone on price.
Oh My Pi solved the most tasks but took over four minutes each to do it. None of the four swept every category, and success rates across the board stayed fairly close, with one exception.
The results raise a practical question for anyone building on top of these models: what you're actually paying for isn't just intelligence, it's the scaffolding around it.
AI tooling company Composio tested DeepSeek V4 Flash across four agent frameworks (Claude Code, Codex, OpenCode, and Oh My Pi) on 30 tasks using real-world tools like Gmail, GitHub, Slack, and Notion. No single framework won across all categories. Oh My Pi had the highest success rate (17/30) but was the slowest at 272 seconds per task.
Why this matters This is a useful reminder that the model isn't the only variable that matters. Composio held DeepSeek V4 Flash constant and still got four different cost, speed, and success profiles just by swapping the wrapper. That's a real signal for anyone building on agent frameworks right now: pick one for coding speed like Claude Code and you're paying nearly triple OpenCode's per-task cost.
Pick Oh My Pi for reliability and you're waiting more than four minutes per task. There's no framework that wins on all three axes, which means teams need to actually define what they're optimizing for before choosing a stack, rather than defaulting to whatever's most hyped. For founders watching burn rate, the $0.073 versus $0.195 gap compounds fast at scale.
For researchers, the fact that Claude Code used the fewest tool calls and least output but still cost the most suggests pricing isn't just a function of efficiency, it's a function of how the vendor built the wrapper. Worth testing your own workload against more than one framework before committing.

Common Questions Answered
Why did Composio test the same DeepSeek V4 Flash model across different agent frameworks?
Composio wanted to demonstrate that the agent framework wrapper matters almost as much as the underlying model itself. By keeping the model constant and only changing the framework, they could isolate and measure how each wrapper affects performance metrics like speed, cost, and success rate across real-world tasks.
What was Claude Code's performance advantage over other agent frameworks in the Composio benchmark?
Claude Code finished tasks the fastest at an average of 122 seconds while using fewer tool calls than competitors. However, this speed advantage came at a significant cost premium, with Claude Code charging nearly three times more per task than the cheapest alternative, OpenCode.
Which agent framework had the highest success rate in the Composio testing, and what was its trade-off?
Oh My Pi achieved the highest success rate with 17 out of 30 tasks completed successfully, making it the most reliable framework tested. The major trade-off was speed, as Oh My Pi was the slowest framework at 272 seconds per task on average, meaning users had to wait over four minutes per task for that reliability.
What real-world tools and applications did Composio use to test the agent frameworks?
Composio tested the frameworks on 30 tasks that involved practical integrations with Gmail, GitHub, Slack, and Notion. These tools represent the types of actual work that AI agents are deployed to handle in real-world scenarios.
What key insight does the Composio benchmark reveal about choosing an agent framework?
The benchmark shows there is no single best framework across all categories, forcing developers to make trade-offs based on their priorities. Teams must choose between speed (Claude Code), cost-efficiency (OpenCode), or reliability (Oh My Pi), understanding that optimizing for one metric often means compromising on others.
