Either way, you pay for the model calls. A median coding-agent day on our gateway is 95 requests and 8.6 million tokens. The table prices every step at one model’s rate.
Both run on Standard Compute, where each step goes to the cheapest model that can do it: routine steps go to efficient open models, hard ones to frontier models such as Claude Fable 5.1 or GPT-6 Astra.
| Model | Typical day | Busy day |
|---|---|---|
| Claude Opus 5.5 | $7.34 | $59.10 |
| Claude Sonnet 5.5 | $3.67 | $29.55 |
| GPT-6 Luna | $0.23 | $2.43 |

ClinePiChoose Cline if you are developers who want a powerful, safety-gated agent inside the editor they already use. Choose Pi if you are developers who want a fast, minimal, hackable terminal agent with full control over context and models.
In our editorial scoring, Cline leads in 3 of six categories (output quality, autonomy and ease of use), while Pi leads in 2 (speed and value). On price, Cline runs free (byo api key) and is open source; Pi runs free (mit), bring your own model and is open source.
Across 18 community votes on this matchup, Cline currently leads in 5 of six categories. Cast your own vote above to move the needle.

Cline is the open-source coding agent that defined the in-editor agent category, with 11M+ installs across VS Code, JetBrains, Cursor, its CLI and a new desktop app. Its Plan/Act modes separate thinking from doing: the agent proposes a plan you approve before it touches files or runs commands. Apache-2.0 licensed with full bring-your-own-key model freedom, MCP integration, and deployment options up to on-prem and air-gapped for enterprises.
Pi is an open-source terminal coding agent and agent harness created by Mario Zechner (badlogic, creator of libGDX) and published under MIT by Earendil. Its philosophy is radical minimalism: by default the model gets a small set of tools (read, write, edit, bash), and everything else, from subagents to plan mode, lives in TypeScript extensions. That keeps the loop fast, the context clean, and the behavior fully under your control. It supports 30+ model providers with mid-session switching, session branching and compaction for long tasks, and custom OpenAI-compatible providers via a simple models.json.
