GPT-5.5
OpenAI · Lanzado abr 2026
GPT-5.5 is OpenAI's April 2026 general-purpose model at $5 input and $30 output per 1M tokens, with a 1M+ token context (922K in, 128K out). It is no longer OpenAI's only deployable frontier option: the GPT-5.6 family is on the public price list, and GPT-6 Sol lists at $2/$10. It stays recommended as a stable, widely supported production baseline, but new workloads should test GPT-6 Sol or GPT-5.6 Terra first.
¿Es adecuada para ti?
Bueno para
- Existing OpenAI production workloads already validated on it: generally available with broad tooling, Responses and Chat Completions support, and image input
- Complex professional workloads needing strong reasoning and a 1M+ token context window (922K input)
- Teams already on the OpenAI ecosystem — broad tooling, Responses + Chat Completions API support, image input
No recomendado para
- Pure price-performance on specific tasks — Gemini 3.5 Flash ties it on OSWorld at 1/3 the cost; GPT-5.6 Terra claims GPT-5.5-class perf at half price
- Very-long-context sessions — prompts over 272K input tokens are billed at 2x input / 1.5x output for the whole session
- New deployments chosen on price: GPT-6 Sol lists at $2 input / $10 output per 1M tokens short context, against GPT-5.5's $5 / $30

Pricing unchanged: gpt-5.5 (<272K) $5/$0.50 cached/$30 matches scalars. Stale self-authored prose: summary, strengths best_for[0] and audience for_whom[0] said the GPT-5.6 family 'stays government-gated'; the pricing page lists gpt-5.6-sol/terra/luna as standard rows and gpt-6-sol at $2/$10 (changelog Sep 22). REFRESHED via model_update: best_for[0] and for_whom[0] rewritten, avoid_for added (GPT-6 Sol $2/$10 vs $5/$30). Summary corrected via verdict_set 3f42e5e5-7b59-422d-8167-9b038fcb7515. rating_before=recommended, rating_after=recommended (held; operator ruling needed on rating for a superseded model). No draft: correction of own prose, no vendor event.
