Claude Haiku 5.5 (Max) (Anthropic) and GPT-6.1 Sol (Max) (OpenAI) are not peers on the headline index, which makes the trade-offs the interesting part. The clearest gap is on the bill: GPT-6.1 Sol Max is 20 times the blended price of Claude Haiku 5.5 Max. Everything below is read from the benchmark, price and speed data in Franklin AI's catalogue; nothing here comes from a hands-on test.

What they cost

The list prices are $0.10 in and $0.50 out for Claude Haiku 5.5 Max, and $2.00 in and $10.00 out for GPT-6.1 Sol Max, per million tokens. That makes Claude Haiku 5.5 Max's output 95% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $0.20 on Claude Haiku 5.5 Max and $4.00 on GPT-6.1 Sol Max. For an agent that reads 50 million tokens and writes 5 million in a month, Claude Haiku 5.5 Max would come in 95% lower: $7.50 for Claude Haiku 5.5 Max against $150 for GPT-6.1 Sol Max.

Reasoning and overall scores

On the intelligence index, Claude Haiku 5.5 Max scores 36.5 against 54.6 for GPT-6.1 Sol Max. These scores put the two models in different leagues on overall capability. In relative terms, GPT-6.1 Sol Max scores 50% higher.

Among 109 active scored models, Claude Haiku 5.5 Max sits 37th and GPT-6.1 Sol Max 8th.

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

Value for money

Per point of intelligence index, Claude Haiku 5.5 Max costs $0.0055 of blended price per million tokens and GPT-6.1 Sol Max $0.073. So GPT-6.1 Sol Max buys its higher score at a premium, while Claude Haiku 5.5 Max is the value pick, paying 93% less per point.

When they came out

Claude Haiku 5.5 Max arrived on October 7, 2026, 8 days after GPT-6.1 Sol Max (September 29, 2026). That is close enough to count them as the same generation.

How fast they respond

Measured output speed is 233 tokens per second for Claude Haiku 5.5 Max and 60 tokens per second for GPT-6.1 Sol Max. Claude Haiku 5.5 Max is ahead by 291% on throughput. The wait for the first token averages 4.6 minutes on Claude Haiku 5.5 Max against 5.4 minutes on GPT-6.1 Sol Max. Claude Haiku 5.5 Max gets to its first token 1.2 times as fast. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

For a 1,000-token response, first token plus generation comes to roughly 4.7 minutes on Claude Haiku 5.5 Max and 5.7 minutes on GPT-6.1 Sol Max.
