Claude Haiku 5.5 (Max) from Anthropic and GPT-6.1 Terra (Max) from OpenAI sit in different tiers of the catalogue. All numbers are the catalogue's recorded values; nobody ran either model by hand for this page. The clearest gap is on the bill: GPT-6.1 Terra Max is 10 times the blended price of Claude Haiku 5.5 Max.

Price per token

Claude Haiku 5.5 Max lists $0.10 per million input tokens and $0.50 per million output tokens; GPT-6.1 Terra Max lists $1.00 and $5.00. GPT-6.1 Terra Max costs 10 times as much per output token.

Take 1 million input tokens and 200,000 output tokens: that comes to $0.20 on Claude Haiku 5.5 Max and $2.00 on GPT-6.1 Terra Max. For summarising 1,000 documents of 8,000 tokens into 400-token summaries, Claude Haiku 5.5 Max would come in 90% lower: $1.00 for Claude Haiku 5.5 Max against $10.00 for GPT-6.1 Terra Max.

Claude Haiku 5.5 Max is the faster writer

Claude Haiku 5.5 Max generates about 233 tokens per second and GPT-6.1 Terra Max about 114 tokens per second. That makes Claude Haiku 5.5 Max roughly twice as fast at writing. Time to first token is 4.6 minutes for Claude Haiku 5.5 Max and 6.2 minutes for GPT-6.1 Terra Max. GPT-6.1 Terra Max waits 1.3 times as long before its first token. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

For an 800-token response, first token plus generation comes to roughly 4.7 minutes on Claude Haiku 5.5 Max and 6.3 minutes on GPT-6.1 Terra Max.

Generation gap

Claude Haiku 5.5 Max came first, on October 7, 2026; GPT-6.1 Terra Max followed on October 26, 2026. They are effectively contemporaries.

How the intelligence index compares

On the intelligence index, Claude Haiku 5.5 Max scores 36.5 against 51.3 for GPT-6.1 Terra Max. This is a substantial lead, not a near miss.

Across the 109 active models with an intelligence score in the catalogue, Claude Haiku 5.5 Max ranks 37th and GPT-6.1 Terra Max ranks 14th.

Specialist coding and math indexes are missing for both, so treat the overall score as the only capability signal here.

Score per dollar

Dividing the blended price by the intelligence index gives a rough cost per point: $0.0055 for Claude Haiku 5.5 Max and $0.039 for GPT-6.1 Terra Max, per million tokens. So GPT-6.1 Terra Max buys its higher score at a premium, while Claude Haiku 5.5 Max is the value pick, paying 86% less per point.
