GPT-Image-2.5 Flare vs Kimi K3
Values come from GPT-Image-2.5 Flare and Kimi K3, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Input price
- Kimi K3 at $3/M against $30/M — 10.0× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- GPT-Image-2.5 Flare at $2/M against $15/M — 7.5× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Kimi K3 publishes weights (Modified MIT (commercial use permitted; weights publicly downloadable)); GPT-Image-2.5 Flare is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- GPT-Image-2.5 Flare shipped 54 days after Kimi K3 (2026-09-08 vs 2026-07-16).
