🔥 Game of the night: Claude vs. GPT in the scoring race
Claude Opus 4.8 posts an Intelligence Index of 61 to GPT-5.5's 60 — a one-point margin that is statistically tight on Artificial Analysis's composite methodology, but Claude has now held the top position across successive measurements. GPT-5.5 remains the higher-volume franchise: it fields three active pricing tiers (xhigh, high, medium) priced at a flat $4.35/1M blend compared to Claude Opus 4.8's $4.10/1M, a 6% pricing edge for Anthropic at equal performance.
Meanwhile, the legacy GPT-4o line (not on the current Artificial Analysis front page) has been effectively benched in favor of the GPT-5 series. OpenAI's pricing page no longer lists standalone GPT-4o rates — the franchise is running on a GPT-5.4 / GPT-5.5 two-tier rotation.
23⚡ Speed panel — tokens per second (Artificial Analysis live)
This is where the scoreboard gets interesting. Intelligence and speed almost never correlate.
| Team | Model | Output speed (t/s) | TTFT (s) | Speed tier |
|---|---|---|---|---|
| Google (Gemini) | Gemini 3.5 Flash | 207 t/s | 16.2s | 🚀 Season-high |
| Google (Gemini) | Gemini 3.1 Flash-Lite | 268 t/s | 5.7s | 🚀 Fastest Gemini |
| Anthropic (Claude) | Claude Sonnet 4.6 (Reasoning Max) | 120 t/s | 110.7s | ⚡ Fast-reasoning |
| Anthropic (Claude) | Claude Haiku 4.5 | 97 t/s | 16.9s | ⚡ Budget burner |
| xAI (Grok) | Grok 4.3 (high) | 182 t/s | 12.5s | 🏃 Underrated pace |
| OpenAI (GPT) | GPT-5.5 (xhigh) | 40.7 t/s | 49.1s | 🐢 Deliberate |
| DeepSeek | DeepSeek V4 Pro (Reasoning Max) | 50 t/s | 1.8s | ⚡ Low TTFT |
Season stat: Gemini 3.5 Flash's 207 t/s is the fastest production speed among models in the AI Index top 10 score bracket (55+). Google may be outside the intelligence top 5, but they're running the fastest offense of any team in that tier.
Grok's quiet hustle: Grok 4.3 (high) at 182 t/s with 12.5s TTFT punches above its Intelligence Index rank of 53. If xAI can close the scoring gap, the speed advantage becomes a real weapon.
💰 Pricing war analysis — the cost-per-point breakdown
The real competition is in the value tier — Intelligence Index points per dollar of API cost.
| Team | Flagship model | Input $/1M | Output $/1M | AI Index | Points per $1 output |
|---|---|---|---|---|---|
| DeepSeek | V4 Pro (75% promo) | $0.435 | $0.87 | 52 | 59.8 |
| Gemini 3.5 Flash | $0.30* | $2.50* | 55 | 22.0 | |
| xAI | Grok 4.3 | $1.25 | $2.50 | 53 | 21.2 |
| Gemini 2.5 Pro | $1.25 | $10.00 | 35 | 3.5 | |
| Anthropic | Claude Sonnet 4.6 | $3.00 | $15.00 | 52 | 3.5 |
| OpenAI | GPT-5.5 | $5.00 | $30.00 | 60 | 2.0 |
| Anthropic | Claude Opus 4.8 | $5.00 | $25.00 | 61 | 2.4 |
Gemini 2.5 Pro/Flash pricing from Google AI Developer pricing page; DeepSeek pricing per official API docs (75% discount valid through May 31, 2026 UTC); Grok from xAI API page.
23456DeepSeek's fire sale
DeepSeek's V4 Pro is currently on a 75% promotional discount — output at $0.87/1M versus the post-promotion rate of $3.48/1M. With an Intelligence Index of 52, it delivers roughly 60 AI-index points per dollar of output, compared to GPT-5.5's 2.0. This promo expires May 31, 2026. If DeepSeek holds that line post-discount, it becomes a real threat to the mid-market. If it reverts to full price, the equation changes entirely.
The macro pattern: Google and DeepSeek are playing a volume game. Gemini 3.5 Flash at $0.30/$2.50 in/out and Gemini 2.5 Flash at $0.30/$2.50 are the lowest-priced capable models from any named team. Google's free tier (via Google AI Studio) makes it the only franchise offering zero-cost access to a competitive model.
📊 Context window depth chart
| Team | Model | Context window | Field advantage |
|---|---|---|---|
| Meta (Llama) | Llama 4 Scout | 10M tokens | Widest context in the league |
| xAI (Grok) | Grok 4.20 / 4.1 Fast | 1M tokens | Second-widest |
| Google (Gemini) | Gemini 1.5 Pro (May) | 1M tokens | Third-widest |
| Anthropic (Claude) | Claude Opus 4.8 | 1M tokens | Tied third |
| OpenAI (GPT) | GPT-5.5 | 922k tokens | Slight edge over prior 128k window |
| DeepSeek | DeepSeek V4 Pro/Flash | 1M tokens | Full million |
Meta's Llama 4 Scout at 10 million tokens is the long-haul freight runner of this league — no other model is within 10x of its context capacity. That's a specialized stat, but for enterprises running massive document pipelines it's a decisive edge.
1🆕 Challenger watch — challengers making noise this cycle
- Kimi K2.6 (Moonshot AI) — Intelligence Index 54, ranking it above DeepSeek V4 Pro and all named Grok variants. Priced at $0.70/1M blend. An unseeded challenger crashing the main draw.
- Mistral Medium 3.5 — AI Index 39, 152 t/s, priced at $2.10/1M blend. Solid mid-tier performance, especially for EU-regulated deployments.
- Cohere Command A+ — AI Index 37, 223 t/s output speed — the highest raw token throughput on the entire leaderboard among models with a price listed. Zero-cost pricing (free tier). Useful for latency-critical applications but the intelligence gap versus tier-1 models is wide.
🏁 Postgame summary
Claude Opus 4.8 holds the scoring record. GPT-5.5 stays in contention on depth and ecosystem. Google's Gemini family is running the fastest offense in the ability-tier. DeepSeek's discount is the price-war story of the cycle — $0.87/1M output won't last past May 31. Meta's Llama 4 Scout has a context advantage no other franchise can touch. Grok is faster than its rankings suggest.
The teams that should be watching? Anyone who isn't Google or DeepSeek in the budget tier is currently fighting for value at a significant per-token disadvantage.
