Claude Code is the fastest agent framework but costs nearly three times more than the cheapest rival
Claude Code is 3x pricier per task than OpenCode, but speed matters more than you think in agent frameworks.

Why it matters
Agent framework choice is shifting from capability to economics: practitioners now have benchmarked cost-vs-speed tradeoffs across real production tasks, forcing budget vs latency decisions into deployment planning.
The key facts
13 to knowComposio benchmark: 30 real-world tasks across 4 agent frameworks
Claude Code: $0.195/task, fastest execution, fewest tool calls
OpenCode: $0.073/task, cheapest option
3x cost spread across frameworks despite similar success rates
Model tested: Deepseek V4 Flash
Success rates 'mostly similar' across frameworks
Composio tested Deepseek V4 Flash across 4 agent frameworks
30 real-world tasks evaluated
Claude Code: $0.195 per task (fastest, fewest tool calls/output tokens)
OpenCode: $0.073 per task (cheapest)
3x cost variance between frameworks
Success rates mostly similar across frameworks
Framework choice driven by price and speed trade-offs

Publisher excerpt: Composio tested Deepseek V4 Flash across four agent frameworks on 30 real-world tasks. Success rates were mostly similar, but costs varied by nearly 3x: OpenCode came in cheapest at $0.073 per task, while Claude Code cost $0.195 despite using the fewest tool calls and output tokens.
