Repository Issue Resolution
78.2%
OpenHands SWE-Bench resolved
Direct OpenHands SWE-Bench outcomes for resolving real repository issues with a pinned OpenHands agent and language-model configuration.
Scores are official OpenHands SWE-Bench resolved percentages for exact OpenHands and model configurations, not bare-model scores or SpringPrompt predictions. Twenty-nine exact task sidecars support marginal 95% bootstrap score intervals; five rows explicitly have no interval. No full-cohort rank confidence is claimed.

Structured Output Reliability
86.03%
Direct benchmark score
Directly measured ability to return accurate values in the requested structured schema across the benchmark's evaluated text, image and audio modalities.
Point order reproduces the source's direct Overall score. Rank ranges come from overlap of marginal record-cluster bootstrap intervals for Overall; they are not simultaneous confidence intervals for rank.

Early-user signal
Initial community opinions
A paraphrased editorial synthesis of 4 Reddit discussions created in the 14 days after launch (23 Apr 2026 to 7 May 2026). Anecdotal context only — it never affects scores or rankings.
In the search-indexed launch-window sample, GPT-5.5 was frequently praised for speed, focus, complex debugging, planning, and more natural chat responses. The main caveats were heavier usage at high effort, uneven frontend work, rollout or integration differences, and dependence on the surrounding Codex harness. Reports suggested a practical productivity gain for many workflows but not a uniform change across coding specialties.

Business Skills V3 · proposed
How Spring Prompt plans to test GPT-5.5
The setup below is proposed and may change until preflight and execution approval are complete. Existing benchmark evidence above does not authorize or stand in for a Business Skills V3 result.
- Proposed reasoning
- High reasoning
- Provider revision
- Exact provider revision will be resolved and frozen only after preflight and execution approval
- Tools and service
- No tools · Provider-default service tier
- Planning configuration
- gpt-5.5-high
- Generation controls
- Provider-managed reasoning; no temperature override proposed

Model comparisons
Compare GPT-5.5 side by side
Editorially reviewed comparisons appear first. Every page matches only benchmark records with the same reviewed protocol key and does not manufacture an overall winner.
Publication safeguards
What must pass before a V3 result appears
- 1First-party task-local comparisons and eligible external evidence must both be present.
- 2Model and provider configuration identity must match the reviewed release exactly.
- 3Coverage, reliability, judge diagnostics, and sealed stability checks must pass.
- 4Uncertainty and missing evidence remain visible when results are published.
Stable family URL
Evidence can grow without changing the page
New reviewed benchmark snapshots, operational facts, community themes, and early field-test syntheses can be added here while the canonical model-family identity remains fixed.
