OpenCode

Composio benchmarked DeepSeek V4 Flash across four agent frameworks—Claude Code, Codex, OpenCode, and Oh My Pi—on 30 real-world tasks. Claude Code finished fastest at 122 seconds per task but cost $0.195, nearly three times OpenCode's $0.073, while Oh My Pi had the highest success rate at 17/30 but took 272 seconds per task.

OpenCode shipped v1.14.25 with Roslyn LSP support for Razor, .cshtml, and C# script files. The release fixes GPT-5.5 with OpenAI OAuth to use correct context limits and adds request details to LSP permission prompts.
