This matchup crosses tiers: GPT-6.1 Terra (Max) from OpenAI against Tencent Hy4 from Tencent. The biggest separation is in overall capability: 51.3 for GPT-6.1 Terra Max against 34.6 for Tencent Hy4. Everything below is read from the benchmark, price and speed data in Franklin AI's catalogue; nothing here comes from a hands-on test.

The headline benchmark

On the intelligence index, GPT-6.1 Terra Max scores 51.3 against 34.6 for Tencent Hy4. These scores put the two models in different leagues on overall capability. In relative terms, GPT-6.1 Terra Max scores 48% higher.

Across the 109 active models with an intelligence score in the catalogue, GPT-6.1 Terra Max ranks 14th and Tencent Hy4 ranks 42nd.

Neither model has a separate coding or math index recorded yet, so those narrower comparisons will have to wait for more data.

Throughput and time to first token

Once a response is under way, GPT-6.1 Terra Max produces roughly 114 tokens per second against 94 tokens per second for Tencent Hy4. GPT-6.1 Terra Max is ahead by 22% on throughput. Time to first token is 6.2 minutes for GPT-6.1 Terra Max and 2.4 seconds for Tencent Hy4. GPT-6.1 Terra Max writes faster once it starts, but Tencent Hy4's head start is large enough that Tencent Hy4 still finishes first at any typical reply length; GPT-6.1 Terra Max only catches up beyond about 190,000 tokens. A first-token wait of that length suits background work better than live conversation.

Add the two numbers up for a 600-token reply and Tencent Hy4 finishes first: 6.3 minutes for GPT-6.1 Terra Max, 8.8 seconds for Tencent Hy4.

Running costs

The list prices are $1.00 in and $5.00 out for GPT-6.1 Terra Max, and $0.834 in and $2.501 out for Tencent Hy4, per million tokens. GPT-6.1 Terra Max costs twice as much per output token.

Take 1 million input tokens and 200,000 output tokens: that comes to $2.00 on GPT-6.1 Terra Max and $1.33 on Tencent Hy4. For an agent that reads 50 million tokens and writes 5 million in a month, Tencent Hy4 would come in 28% lower: $75.00 for GPT-6.1 Terra Max against $54.20 for Tencent Hy4.

Generation gap

Tencent Hy4 arrived on November 3, 2026, 8 days after GPT-6.1 Terra Max (October 26, 2026). They are effectively contemporaries.

Score per dollar

Per point of intelligence index, GPT-6.1 Terra Max costs $0.039 of blended price per million tokens and Tencent Hy4 $0.036. So neither is a bargain relative to the other; you pay for what the index measures.
