Rate limit reached for gpt-5.4 in organization org-xxx on tokens per min. Limit: 500000 / min. Current: 487234 / min. (error.type: rate_limit_exceeded) vs (error.type: insufficient_quota) Understand and manage OpenAI TPM (tokens per minute) limits when using long-context models like GPT-5.4/GPT-5.5 with 100k+ input tokens Includes evidence for OpenAI API troubleshooting demand.
tokens_per_min (TPM) rate limit exceeded — single call with 100k context tokens consumes large fraction of TPM budget Fix Anthropic Vertex AI 413 error rejecting legitimate payloads under 32MB; differentiate between real prompt length limits vs incorrect rate-limit misreporting as 413 Includes evidence for Anthropic API troubleshooting demand.
Error code: 413 - Prompt is too long (when payload is only ~2MB, well under documented 32MB limit) Understand and fix insufficient_quota error returned by OpenAI API; find proper exception handling for quota exceeded scenarios Includes evidence for OpenAI API troubleshooting demand.

authentication_error (401) mid-session autonomous run Debug and fix Claude Code MCP -32000 generic server error where MCP server process crashed during initialization or exited mid-handshake Includes evidence for Claude Code troubleshooting demand.
Connection closed. (Picking well-maintained servers avoids a lot of this.) MCP -32000 Fix MCP server reconnection failure after OAuth authentication succeeds in Claude Code using streamable-http transport Includes evidence for Claude Code troubleshooting demand.
Authentication successful, but server reconnection failed Troubleshoot and fix Cloudflare 520 error caused by origin server crashes, header size limits, firewall blocking, or short idle timeouts Includes evidence for Cloudflare troubleshooting demand.

429 Temporary suspicious activity rate limit restriction Developers integrating third-party APIs via LiteLLM proxy encounter BadRequestError when Azure backend rejects stream_options.include_usage parameter. Need compatible configuration or workaround Includes evidence for LiteLLM troubleshooting demand.
litellm.BadRequestError: AzureException BadRequestError: Unknown parameter: stream_options.include_usage Users report that the OpenAI Codex desktop extension rapidly depletes token usage after an update — just 1–2 prompts drop usage by 1%. Users want to understand why tokens are consumed excessively and how to fix/prevent it Includes evidence for GitHub Copilot troubleshooting demand.
tokens burning very fast following extension update Fix unexpected 429 errors on Claude Code Max plan even when dashboard shows sufficient available quota; requires debugging discrepancy between dashboard counters and actual API enforcement. Includes evidence for Anthropic API troubleshooting demand.
rate_limit_error: 429 Rate Limit Exceeded despite dashboard showing available quota Fix rate limiting triggered by running multiple Claude Code instances concurrently; user wants to know if concurrent usage reduces per-session rate limits. Includes evidence for Anthropic API troubleshooting demand.
429 rate limit errors running multiple Claude Code sessions in parallel Fix permission denied errors in GitHub Actions workflows when attempting to commit and push changes back to repository. Includes evidence for GitHub Actions troubleshooting demand.
Permission denied when pushing from GitHub Actions workflow; requires Personal Access Token workaround Fix extremely slow GitHub OAuth authentication flow in Claude Code MCP server; user spends hours with no feedback when auth fails. Includes evidence for Claude Code troubleshooting demand.
GitHub MCP Server: 2 hours to fail authentication; no progress indicator during auth process Fix API returning 429 due to account quota exhaustion rather than rate limiting; user needs to know it's a billing issue, not a retry issue. Includes evidence for OpenAI API troubleshooting demand.
insufficient_quota: You exceeded your current quota, please check your plan and billing details.
