Copilot AI Credits — Model Pricing Guide

Understand how model selection impacts your organization's AI credit consumption

How Copilot AI Credits Work

Every Copilot interaction that uses a model (Chat, agent mode, Copilot CLI, cloud and third-party coding agents, code review, Spaces, Spark) consumes tokens. Tokens are converted to AI credits based on the model used. 1 AI credit = $0.01 USD.

The cost of a single interaction depends on:

Code completions are free. Inline code suggestions (the gray text that appears as you type) and next edit suggestions do not consume AI credits.

Included Credit Pools (Business & Enterprise Plans)

Each seat's included credits go into a shared pool. In the State enterprise, IOT caps each agency's draw on that pool at the credits its own seats contribute.

PlanCredits/Seat/Month10-Seat Pool50-Seat Pool
Copilot Business ($19/seat)1,90019,00095,000
Copilot Enterprise ($39/seat)3,90039,000195,000

Once the pool is exhausted, additional usage is billed at $0.01 per credit, unless IOT has set a $0 budget with "Stop usage" for the agency. Unused credits don't carry over, and the pool resets at 00:00 UTC on the 1st of each month.

Model Pricing (Per 1M Tokens → AI Credits)

All prices below are per 1 million tokens. To convert to AI credits: multiply the dollar rate by 100 (since 1 credit = $0.01).

OpenAI Models

GPT-5.6 and GPT-6 models include a cache write cost. Earlier OpenAI models do not.

Rows marked long context apply when a request's input passes the threshold shown. Copilot code review picks its model automatically and does not disclose it, so its per-token cost can vary.

Practical Cost Examples

A typical Chat interaction uses roughly 2,000 input tokens + 1,000 output tokens. Here's what that costs across models:

ModelCategoryCost per ChatCredits UsedChats per 1,900 credits
GPT-6 LunaLightweight~$0.0007~0.07~27,143
GPT-5.4 nanoLightweight~$0.0017~0.165~11,515
GPT-5 miniLightweight~$0.0025~0.25~7,600
Claude Sonnet 5Versatile~$0.014~1.4~1,357
GPT-5.4Versatile~$0.020~2.0~950
Claude Sonnet 4.6Versatile~$0.021~2.1~905
Claude Opus 4.8 / 5Powerful~$0.035~3.5~543
GPT-5.5Powerful~$0.040~4.0~475
Claude Fable 5Powerful~$0.070~7.0~271

Based on ~2K input + ~1K output tokens per interaction. Agent mode sessions use significantly more tokens (10K–100K+ per session).

Agent Mode Example

A typical agent session (multi-step code generation, file edits, terminal commands) might consume 50,000 input + 10,000 output tokens:

GPT-6 Luna: (50K × $0.10/1M) + (10K × $0.50/1M) = $0.01 → ~1 credit
GPT-5.4 nano: (50K × $0.20/1M) + (10K × $1.25/1M) = $0.0225 → ~2.25 credits
Claude Sonnet 4.6: (50K × $3.00/1M) + (10K × $15.00/1M) = $0.30 → ~30 credits
Claude Opus 4.8: (50K × $5.00/1M) + (10K × $25.00/1M) = $0.50 → ~50 credits
GPT-5.5: (50K × $5.00/1M) + (10K × $30.00/1M) = $0.55 → ~55 credits
Claude Fable 5: (50K × $10.00/1M) + (10K × $50.00/1M) = $1.00 → ~100 credits
Key takeaway: The same agent session costs about 100× more on Claude Fable 5 than on GPT-6 Luna. A developer using powerful models (Opus, GPT-5.5, Fable) in agent mode can use up their share of the credit pool many times faster than one using lightweight models. Model choice is the biggest lever for cost control.

Cost Control Recommendations

Enterprise control: In the State enterprise, IOT sets which models are available at the enterprise level, and organization owners can't change it. Within those models, steering developers toward lightweight and versatile models is the most effective cost control.
