Here is how Claude Opus 5 (Max), built by Anthropic, lines up against GPT-6.1 Sol (Max) from OpenAI. The figures come from tracked catalogue data, not from our own testing, so treat them as a starting point for a trial on your tasks. GPT-6.1 Sol Max leads the intelligence index 54.6 to 44.2, a gap of 10.4 points.

Reasoning and overall scores

GPT-6.1 Sol Max comes out ahead on the intelligence index, 54.6 to 44.2. That is a wide gap for an aggregate score.

Across the 109 active models with an intelligence score in the catalogue, Claude Opus 5 Max ranks 26th and GPT-6.1 Sol Max ranks 8th.

There are no coding or math index scores for either model in the catalogue, which keeps this comparison at the aggregate level.

Price per token

Claude Opus 5 Max lists $5.00 per million input tokens and $25.00 per million output tokens; GPT-6.1 Sol Max lists $2.00 and $10.00. That makes GPT-6.1 Sol Max's output 60% cheaper.

For a sample workload of 1 million input tokens and 200,000 output tokens, Claude Opus 5 Max would cost $10.00 and GPT-6.1 Sol Max $4.00, a difference of $6.00. Scale it up to writing 2,000 drafts of 2,000 output tokens from 300-token prompts and the bill is $103 for Claude Opus 5 Max against $41.20 for GPT-6.1 Sol Max. Blended at three input tokens per output token, the effective rates are $10.00 for Claude Opus 5 Max and $4.00 for GPT-6.1 Sol Max.

Throughput and time to first token

Claude Opus 5 Max generates about 50 tokens per second and GPT-6.1 Sol Max about 60 tokens per second. That makes GPT-6.1 Sol Max roughly 1.2 times as fast at writing. Time to first token is 62 seconds for Claude Opus 5 Max and 5.4 minutes for GPT-6.1 Sol Max. On total time, Claude Opus 5 Max wins at ordinary lengths; GPT-6.1 Sol Max's higher throughput only pays off beyond about 81,000 tokens. A first-token wait of that length suits background work better than live conversation.

Put together, a 400-token answer would take about 70 seconds from Claude Opus 5 Max and 5.5 minutes from GPT-6.1 Sol Max, counting the first-token wait.

Score per dollar

Per point of intelligence index, Claude Opus 5 Max costs $0.23 of blended price per million tokens and GPT-6.1 Sol Max $0.073. With the higher score and the lower cost per point, GPT-6.1 Sol Max is the better value per point on these numbers.
