Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on instruction-tuned model variants, and multiple model sizes for cost/performance flexibility caught me off guard. Less widely adopted than GPT or Claude models is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Years in this space

I've evaluated a lot of these over the years. What stands out here is multilingual language support — handled better than most — and available via API and major cloud platforms. Smaller third-party ecosystem and tooling is my one real gripe. Worth the time if this is your use case.

Solid for our team

We rolled this out across the team last quarter and handles multilingual text. Multilingual language support fits neatly into how we already work, and instruction-tuned model variants removed a step we used to do by hand. Usage costs can rise with high-volume workloads, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. Text generation and completion API just works and supports custom fine-tuning on private data. Less widely adopted than GPT or Claude models can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.
