Quick start

Call GPT 5.6 Sol with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5.6-sol",
    max_tokens=4000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.1200 per call at standard rates
# Input:  $4.00/MTok
# Output: $20.00/MTok

Cheapest viable option: Claude Sonnet 5 at $0.0600/call (50% less, 90/100 quality).

What drives legal analysis cost

Legal work is heavy on both sides: long source documents in, detailed analysis out. It is also the case where accuracy is worth the most, so the cheapest-viable-model logic that works for classification does not apply. Long contracts frequently cross long-context pricing thresholds, which can re-rate the entire request rather than just the excess.

For GPT 5.6 Sol specifically, that means output tokens cost 5.0x more than input, at $20.00 vs $4.00 per MTok. At this use case’s 10,000/4,000 token split, output accounts for 67% of the $0.1200 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $4.00 to $0.40/MTok. For repeated system prompts, that saves $0.0360 per call.

Batch API: 50% off all tokens

Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.

Frequently asked questions

How much does GPT 5.6 Sol cost for legal analysis per API call?

A typical legal analysis call using GPT 5.6 Sol costs about $0.1200 per call. This estimate uses 10,000 input tokens and 4,000 output tokens at standard rates. Standard rates are $4.00 per million input tokens and $20.00 per million output tokens.

Is GPT 5.6 Sol the best model for legal analysis?

GPT 5.6 Sol scores 96 out of 100 on legal analysis benchmarks overall. It ranks #1 across all 20 models in our cross-provider registry. The highest-ranked model for this task is Claude Fable 5 from Claude. That model scores 98/100 on this task type. Confidence scores are a third-party benchmark snapshot from week 29 of 2026. This snapshot is 8 weeks old, so treat the scores as directional and validate against your own evals.

What is the cheapest model for legal analysis with good quality?

The most affordable model for legal analysis above 80/100 quality is Claude Sonnet 5. It comes from Claude at $2.00 per million input tokens. Output costs $10.00 per million tokens with a quality score of 90/100. Switching from GPT 5.6 Sol to Claude Sonnet 5 saves about 50% per API call.

How can I reduce my GPT 5.6 Sol costs for legal analysis?

Three strategies lower GPT 5.6 Sol costs for this task type effectively. Prompt caching gives a 90% discount on input tokens when reusing system prompts. The batch API gives 50% off all tokens for asynchronous processing workloads. Prompt optimization reduces token counts through more concise instructions and context windows. Combining caching with batching brings your cost from $0.1200 to about $0.006000 per call.

How does GPT 5.6 Sol pricing compare to other GPT models?

GPT has 4 other models alongside GPT 5.6 Sol today: GPT 5.5 at $5.00/$30.00 per million tokens (flagship), GPT 5.4 at $2.50/$15.00 per million tokens (mid-tier), GPT 5.6 Terra at $2.00/$12.00 per million tokens (mid-tier), GPT 5.6 Luna at $0.20/$1.20 per million tokens (fast / budget). The right choice depends on whether your legal analysis workload prioritizes quality, cost, or speed.

What context window does GPT 5.6 Sol support?

GPT 5.6 Sol supports a context window of 1,050K tokens per API call. This sets the maximum combined length of your input prompt and generated response. For legal analysis, typical calls use 10,000 input and 4,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
