# Outages, server errors and capacity or rate errors (`rel.service_errors`)

Feedback Bench, coding agents, built 2026-10-19, window 2026-08-31 to 2026-10-18. Web page: https://feedbackbench.com/coding-agents/#/criterion/rel.service_errors

Area: [Reliability and speed](https://feedbackbench.com/coding-agents/criteria/reliability.md)

**Definition.** Backend unavailability, 5xx or connection errors, capacity errors, and transient 429 errors that do not reflect the user's quota.

**Boundary.** Not this: see [Short rolling usage window blocks or interrupts work](https://feedbackbench.com/coding-agents/criteria/limits.window_interrupts_work.md) and limits.allowance_size for plan quota being reached. Not this: see rel.tool_call_errors for harness tool failures.

Rated user-weeks, all agents: 2472. Complaint share: 93%.

## The brief

Written by large language models from this page's numbers and the posts it quotes, then checked: every number in the text is in the build. Interpretation, not measurement.

No coding agent clearly leads on staying up. Amp and OpenCode sit at the top, but every ranked agent is close to the category norm, and nearly everything users say here is a complaint. Outages and errors are the 13th most rated of 63 criteria, and 92.6% of rated user-weeks on this criterion complain. Google Antigravity is last of the 6 ranked agents. OpenAI Codex users write 44% of the category's complaints here, mostly about the service going down or models being at capacity.

### What separates the best from the rest

No agent ranks high, and none ranks low. The gaps between agents are small, so the kind of failure users describe is what separates them. OpenCode is 2nd of 6, and its users rate this 4.18 times as often as other users. Many of them describe gateways that reject requests and 429 errors that arrive while they still have quota. OpenAI Codex users describe the whole service going down and models that are at capacity.

- **Ranks high**: no agent
- **Ranks low**: no agent

## How it breaks

Rule: A separate pass sorts complaints into failure modes. For each criterion with at least 30 complaining user-weeks, a large language model reads 150 complaint posts drawn at random and names 4 to 8 failure modes; a second large language model then puts every complaint post on that criterion in one mode, or in Other when it fits none. Modes are fixed once named, and new posts are sorted into them each week. A mode counts distinct user-weeks with a complaint in it, per agent; across agents, one user-week per agent. Modes do not change the labels or the Feedback Score. Examples: up to 3 posts per mode from different users, chosen and checked as receipts are.

The largest mode is the total outage, when no request gets through. It makes up 30% of complaining user-weeks, and OpenAI Codex users write 43% of it. Capacity and overload errors belong mostly to OpenAI Codex, which accounts for 64% of that mode. OpenCode users lead two modes: provider and endpoint errors from gateways, and rate-limit errors that arrive while quota remains. In the rate-limit mode they make up 51%.

2319 complaining user-weeks.

| Failure mode | User-weeks | Posts | Agents (user-weeks) | Definition |
|---|---|---|---|---|
| Total service outage blocks all work | 693 | 759 | OpenAI Codex 300, Cursor 125, Claude Code 99, OpenCode 95, Google Antigravity 35, Amp 28, Pi 4, Kiro 3, Devin 2, Cline 1, GitHub Copilot 1 | The agent, its app, or its whole provider is down or unresponsive for minutes to hours, so no request on any model gets through; this excludes errors limited to one model or to capacity messages. |
| Model at capacity or overloaded errors | 462 | 506 | OpenAI Codex 296, Google Antigravity 49, Claude Code 45, OpenCode 40, Cursor 24, Devin 4, Amp 2, GitHub Copilot 1, Factory 1 | Requests are rejected with "model at capacity", "high traffic", 529, or overloaded messages even though the user still has quota, often for one particular model or plan; this excludes full outages and rate limits tied to the user's own usage. |
| Mid-task stream disconnects and server errors | 318 | 335 | OpenAI Codex 116, OpenCode 102, Claude Code 32, Google Antigravity 30, Cursor 15, Amp 7, Cline 6, Devin 4, Pi 3, Factory 1, Kiro 1, Warp 1 | A running task is cut off by 5xx errors, "stream disconnected", empty completions, or connection drops partway through a response, leaving the work incomplete; this excludes requests that fail before they start. |
| Endpoint or provider errors from gateways | 292 | 314 | OpenCode 127, OpenAI Codex 115, Cursor 15, Google Antigravity 12, Claude Code 12, Factory 3, Pi 3, Cline 2, GitHub Copilot 2, Devin 1 | Requests fail straight away with 404, 401, "provider unavailable", "endpoint unavailable", or "no available models" errors from a router, gateway, or subscription proxy even though the model is listed and the user's credentials and balance are valid; this excludes capacity and rate-limit messages. |
| Severe slowness and timeouts under load | 217 | 229 | OpenAI Codex 80, OpenCode 53, Google Antigravity 32, Cursor 22, Claude Code 16, Devin 5, Factory 3, Kiro 3, Cline 2, GitHub Copilot 1 | The service technically responds, but inference or tool calls are so slow, or hit so many timeouts, that the agent is unusable during peak hours; this excludes outright error responses. |
| Spurious rate-limit 429s despite available quota | 175 | 184 | OpenCode 90, OpenAI Codex 40, Google Antigravity 13, Cursor 10, Claude Code 6, Cline 5, Pi 4, Amp 2, Devin 2, Kiro 2, GitHub Copilot 1 | The agent or its gateway returns 429 or "rate limit exceeded" errors, sometimes after the session has been idle, that don't reflect the user's actual consumption or plan limits; this excludes genuine quota exhaustion. |
| Failed requests still consume usage quota | 95 | 100 | OpenAI Codex 44, Claude Code 31, Google Antigravity 11, Cursor 4, OpenCode 3, Cline 1, Devin 1 | Outages, errors, or interrupted runs burn tokens or session limits without producing useful output, or token use spikes after an incident, and no credit is given; this excludes high usage on requests that succeeded normally. |
| Status page denies an ongoing incident | 51 | 54 | OpenAI Codex 30, Claude Code 11, Cursor 6, Google Antigravity 3, OpenCode 1 | The provider's status page shows everything operational, or no official acknowledgment or explanation is given, while users are hitting widespread errors; this excludes the errors themselves. |
| Other | 129 | 140 | OpenAI Codex 56, OpenCode 35, Google Antigravity 14, Claude Code 12, GitHub Copilot 3, Kiro 3, Cursor 2, Cline 1, Devin 1, Factory 1, Pi 1 | Complaints that fit none of the modes above. |

## Top requests

What users ask to add or change, most asked first. 241 user-weeks ask for something. Requests do not change the Feedback Score. Rule: A separate pass by a large language model reads every counted post and extracts what the user asks the agent or its vendor to add or change, with the criteria it maps to and a short normalised wording; it does not touch the labels or the Feedback Score. A large language model groups the wordings within each criterion (the first criterion the request maps to) into themes, and a second pass merges themes that ask for the same change under different criteria; a merged theme sits under the criterion most of its requests map to, and code counts it once. A theme counts distinct user-weeks that ask for it, per agent; across agents, one user-week per agent. Themes asked in fewer than 2 user-weeks, and requests that share no theme, are not shown. Examples: up to 3 posts per theme from different users, without slurs: whole posts of 60 to 450 characters with at least 8 words beyond handles and links, posts of at most 280 characters first, then the newest.

## Posts

Receipts rule: Up to 5 praise and 5 complaint posts per area and 3 per criterion. Each is a whole post of 60 to 450 characters (700 for areas) with at least 8 words beyond handles and links, that judges the criterion, whose labels are all praise or all complaint, and that contains no slur. Posts that touch the fewest criteria come first, then posts of at most 280 characters, then the newest. A second large language model reads the first 3 candidates per slot and keeps a post only if it clearly praises, or clearly complains about, the agent on that criterion. Links and personal details removed by the source show as marks such as [link].
