Claude Haiku 5.5 (Max) from Anthropic and GPT-6 Sol (Max) from OpenAI are both tracked in Franklin AI's benchmark catalogue. Price separates them more than anything else; on a blended basis GPT-6 Sol Max costs 20 times as much as Claude Haiku 5.5 Max. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models.

Price per token

Claude Haiku 5.5 Max lists $0.10 per million input tokens and $0.50 per million output tokens; GPT-6 Sol Max lists $2.00 and $10.00. GPT-6 Sol Max costs 20 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 $4.00 on GPT-6 Sol Max. Scale it up to classifying 100,000 short messages at 150 input tokens and 5 output tokens each and the bill is $1.75 for Claude Haiku 5.5 Max against $35.00 for GPT-6 Sol Max. On a 3:1 blend of input to output tokens, that works out to $0.20 versus $4.00 per million.

Reasoning and overall scores

On the intelligence index, Claude Haiku 5.5 Max scores 36.5 against 44.2 for GPT-6 Sol Max. A lead of this size is hard to dismiss as noise. Put another way, Claude Haiku 5.5 Max would need 21% more on this index to draw level.

Among 109 active scored models, Claude Haiku 5.5 Max sits 37th and GPT-6 Sol Max 26th.

For coding or maths work specifically, the catalogue has no dedicated index on either side yet.

Speed and latency

Once a response is under way, Claude Haiku 5.5 Max produces roughly 233 tokens per second against 127 tokens per second for GPT-6 Sol Max. Claude Haiku 5.5 Max is ahead by 83% on throughput. Before any text appears, Claude Haiku 5.5 Max takes 4.6 minutes and GPT-6 Sol Max 91 seconds. On total time, GPT-6 Sol Max wins at ordinary lengths; Claude Haiku 5.5 Max's higher throughput only pays off beyond about 52,000 tokens. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

For a 400-token response, first token plus generation comes to roughly 4.7 minutes on Claude Haiku 5.5 Max and 94 seconds on GPT-6 Sol Max.

Cost per point of intelligence

A blunt value measure, blended price over intelligence score, puts Claude Haiku 5.5 Max at $0.0055 and GPT-6 Sol Max at $0.090 per point. GPT-6 Sol Max costs 17 times as much per point, which is the price of its lead.

Which is newer

The release dates are September 22, 2026 for GPT-6 Sol Max and October 7, 2026 for Claude Haiku 5.5 Max, 15 days apart. They are effectively contemporaries.
