Calling the provider directly? Use the provider's model name instead, including with [provider-native endpoints](https://developers.cloudflare.com/ai-gateway/usage/providers/) or the provider's own SDK. For example, Anthropic's name for `anthropic/claude-opus-4.8` is `claude-opus-4-8`. - Third-party - Zero data retention GPT-6.1 Sol is OpenAI's newest Sol model, delivering near-Astra performance at a lower cost for complex coding, computer use, and professional work. | Model Info | | | --- | --- | | Context Window [ ↗](https://developers.cloudflare.com/workers-ai/platform/glossary/) | 1,050,000 tokens | | Terms and License | [link ↗](https://openai.com/policies/) | | More information | [link ↗](https://developers.openai.com/api/docs/models/gpt-6.1-sol) | | Zero data retention | Yes | | Request formats | Responses, Chat Completions | | Pricing | | ## Usage ```ts const response = await env.AI.run( 'openai/gpt-6.1-sol', { input: 'A service has 99.9% monthly availability and just had 31 minutes of downtime.

Version breaking changes and keep the old API available during the transition. 2. **Roll out gradually with monitoring:** Start with a small canary group, then increase traffic while tracking error rates, latency, and data correctness. Define thresholds that pause or reverse the rollout. 3. **Test the rollback plan:** Use feature flags or traffic routing to restore the old API quickly. Back up affected data and ensure schema changes remain compatible with the old version. ``` ```json { "id": "chatcmpl-ETWKQsjDdzqugdVw1xUKVJuFad33U", "object": "chat.completion", "created": 1790704490, "model": "gpt-6.1-sol", "choices": [ { "index": 0, "message": { "role": "assistant", "content": "1. **Validate backward compatibility:** Run contract and integration tests against real client workflows.
