| poe | poe | Input: $1.10 | Output: $9.00 | OpenAI's most capable agentic coding model; recommended for use in agentic harnesses or similar environments (e.g. Cursor, Claude Code, Codex); the default reasoning effort is set to `Xhigh` so the model will reason extensively on problems given to it (i.e. expect long generation times) and points-intensive. Accepts image attachments. | |
