Arena Trends: Text-to-Image, Jan 2026 – Apr 2026 For most of the year, Google DeepMind and OpenAI traded the top spot within a tight margin - GPT-Image vs. Nano Banana - with the rest of the field clustered below 1,200. Today, GPT-Image-2 breaks away with a score of 1,512, 242 points ahead of #2 Google. The frontier continues to move.

US vs China update. Stanford's AI Index put the US–China gap at 2.7%. Here's what two years of real-world use from the Text Arena shows. Gap three years ago: +278. Today: +29. Anthropic's Claude Opus 4.6 Thinking vs. Baidu's ERNIE for Developers Ernie 5.1 at the top. The US has never lost #1, but the race keeps closing.

We decided to take Paul Jankura’s Claude Opus 4.5 out for a test drive vs. the current #1 ranking model in Code Arena: Gemini 3 Pro. Same prompt, different outputs. Let’s take a look. Remember, your votes drive the leaderboards. We’ll see how Claude Opus 4.5 stacks up in the coming days! Check out some of the comparisons, like how Claude Opus 4.5 handled the “Pyramids of Giza” prompt, in thread. 🧵

📈Arena Trends Update We pulled Arena scores for the Top 10 labs in Text for the past 6 months (Sept-2025-Feb 2026), and the competitive spread is shifting again. With tighter confidence intervals and new entries in the mix, the frontier continues to shift. Stay tuned for more insights as we dive deeper into the top open models for February later this week. Let us know what you found the most surprising in the comments. 👇

🍌 Thousands of new people jumped into Image Arena Battle mode this week - our intern can barely keep up! What happens in Battle mode? 🧵 We partner directly with model providers to give you early access to cutting-edge models still in development, often before you can try them anywhere else. These pre-release models are tested in Battle mode. Details in the thread 👇

5 patterns in Text Arena's price–performance Pareto frontier since 2023: 1. GPT-4-level quality is now ~500x lower cost. - From a ~$50 blended price per million tokens in 2023 to ~$0.10 today. 2. The higher-price end is both better and lower-priced since 2023. - The leading Arena score has climbed ~170 points (1,330 → 1,500). While the price of the higher-end frontier models dropped from ~$50 to ~$20 per million tokens. 3. The low-cost end gained the most. - Under $0.20 per million tokens, the best available model went from ~1,000 Arena score in 2023 to ~1,440 today. 4. The low-cost/top performance gap has nearly closed. - In 2023, sub-$0.20 models trailed the leader by ~350 Arena points. Today, ~60. 5. The cast has rotated quite a bit. - - OpenAI set the 2023–24 benchmark. - AI at Meta strengthened the low-cost end in 2024. - Google DeepMind drove the 2025 jump. - Anthropic holds the peak in 2026. - xAI and Chinese labs like DeepSeek AI, Z.ai, Kimi.ai, Xiaomi MiMo, and Qwen are continuing to push the mid-price frontier.

You can smell a big model. Not the parameter count. Not the benchmark score. It's that feeling when something is actually reasoning. Not just pattern matching. We call it "big model smell."

📊 After ranking #1, how do model ranks evolve over time? We analyzed how every top performer since mid-2023, when OpenAI’s GPT‑4 was at the top of the leaderboard. As of today, leaders seem to stay at the #1 spot for only 35 days on average. The leading model typically drops out of the top 5 within 5 months, and out of the top 10 within 7 months. Previous leaders have fallen substantially, with o1 now at #56 and Claude 3 Opus at #139 as progress moves faster and faster. We’ll see what 2026 brings.
