OpenAI gives ChatGPT Pro and Business subscribers up to $500 a month in API credits

Terms come from OpenAI's guide.

• Amounts:
• Pro: $100, $200 or $500 a month, matching the tier.
• Business: $20 per paid Standard seat and $100 per paid Premium seat, capped at $500 per workspace per month.
• The first grant is prorated.
• What credits cover: Responses, Agents, Decisions, Realtime and Images APIs, GPT-Live, and built-in tools (web search, file search, Code Interpreter). Codex usage is excluded.
• Eligibility:
• The subscription must be paid and at least seven days old. Free trials don't qualify.
• The ChatGPT and API accounts must use the same email.
• The claimant must own the API organization.
• Enterprise is not eligible.

• Billing order: Free credits are used before purchased credits. Once they run out, requests fail with HTTP 429 and the error credit_balance_exhausted (OpenAI). Client code should treat this as a billing failure, not a rate-limit backoff signal.
• Scope: Credits are tied to one organization and can't be transferred. The organization's normal API rate limits still apply.
• Anthropic's version: It covers the Messages and Batches APIs, Playground, Managed Agents and the Agent SDK. In Claude Code, only claude -p with linked-organization keys counts; interactive Claude Code sessions do not (Pillitteri).
• Implication: Both vendors keep interactive coding-agent use on subscription quotas and separate from API spend.

• The OpenAI amounts and terms come from OpenAI's developer guide and forum announcement. RuntimeWire restates the same terms from OpenAI's materials, so it is not independent confirmation.
• The claim that the deals are "pretty much exactly the same" is Willison's commentary (post). The terms broadly support it. One difference: Anthropic's $500 is a pooled Team cap, not a $500 individual tier (Willison, Oct 7).
• The "promised vs. delivered" gap at Anthropic is reported only by OneHuman. No primary Anthropic source confirms it.
• The rollout problems are user reports on OpenAI's forum, not verified incidents.

• Anthropic moved first, on 7 October. It launched the credits alongside Claude Haiku 5.5, priced at $0.10/$0.50 per million tokens for the first 100k tokens (Willison).
• Business seat rates match across the two vendors: $20 Standard, $100 Premium, and a $500 cap. OpenAI's structure closely mirrors Anthropic's (Pillitteri; OpenAI).
• Startup Fortune separately reported that Anthropic now counts Agent SDK usage separately from subscription limits.

• Use it or lose it: Credits don't roll over. Annual Business plans get a single grant that expires at the end of the annual cycle (OpenAI).
• Downgrades: Moving to Plus, Go or Free removes the organization link at the end of the cycle.
• Rollout friction: Users who subscribed through app stores, and some users at renewal, report claim failures (forum).
• Team value: By OneHuman's arithmetic, a 10-person Anthropic Team gets $500 a month under the pooled cap. That compares with about $1,000 under the reported May terms (OneHuman).

• Individual developers: High-tier subscriptions now fund prototypes, evals and small public demos at no extra cost. That is the use case Willison highlights (post).
• Teams: Budget around the $500 workspace cap. Production systems need paid credits behind the free ones so a credit_balance_exhausted error doesn't take them down.
• Competition: With near-identical offers from both vendors, subscription bundles have become a competitive lever for winning over developers. OpenAI's added Pro $500 tier and Anthropic's pooled Team cap are the main differences.
• Governance: Free credits are tied to an individual's email and organization ownership. Finance and IT should track who owns the linked organizations.
