Provider: Synthetic.new (via Fireworks) Context window: 256k tokens Task: Multi-step tool calling chain (weather → Bulgarian description → markdown file → email with attachment)
| Criteria | Score | Max |
|---|---|---|
| Correct tool call sequence | 3 | 3 |
| Tool call accuracy | 1 | 3 |
| Final output quality | 0 | 2 |
| Efficiency & communication | 0.5 | 2 |
- Time: ~1 min 30 sec
- Cost: Fixed subscription ($20–60/mo on Synthetic.new)
- User interventions: 1 (told model attachment was missing)
Steps 1–3 completed, but step 4 (email with attachment) failed twice:
- Weather data — Retrieved successfully (9°C, fog, high humidity).
- Bulgarian description — Created.
- Markdown file — Created, but file path not provided to user — file was inaccessible.
- Email — Sent twice, both times without the attachment. After user feedback ("файла нет"), the model retried but made the same mistake.
- Attachment not sent — twice. The model either formed the API call incorrectly or couldn't handle the attachment parameter.
- No error recovery — After being told the attachment was missing, it repeated the same broken approach instead of trying an alternative.
- File inaccessible — The markdown file was created somewhere on the server but the path was never shared with the user.
- User got nothing — No file, no attachment, weather data only visible in terminal output.
- Did not show thinking process — just produced final output directly.
- Switched to Bulgarian in terminal output without being asked — violated the communication language (Russian).
- Email body text was decent: "Това е автоматично генериран отчет за времето в София."
Formally went through the steps in the correct order, but the user ended up with nothing. For an agent, this is a failure — the task was not completed, and the model couldn't self-correct even after explicit feedback. The coding-focused model paradoxically couldn't handle a practical tool-calling task.
