TEST_LOG

Tested against the DeepSeek V4 API (DEEPSEEK_API_KEY set) on 2026-05-29.

basic.py

Status: PASS

Description: Sync, sync+streaming, async, async+streaming runs with deepseek-v4-flash. Thinking mode is enabled by default; the model returns content plus reasoning_content.

Result: Responses returned correctly in all four modes.

---

thinking_mode.py

Status: PASS

Description: Compares thinking-enabled (default) vs thinking-disabled (extra_body={"thinking": {"type": "disabled"}}) on deepseek-v4-flash. Confirms reasoning_content is present with thinking on and absent with it off.

Result: Both paths returned valid answers; reasoning_content behaved as expected.

---

reasoning_effort.py

Status: PASS

Description: deepseek-v4-pro with reasoning_effort="max" on a river-crossing puzzle, streamed with full reasoning.

Result: Produced a correct step-by-step solution with streamed reasoning.

---

structured_output.py

Status: PASS

Description: deepseek-v4-flash with a MovieScript schema, run two ways: json_mode_agent (use_json_mode=True) and structured_output_agent (output_schema only, no JSON mode).

Result: Both modes returned valid structured JSON. DeepSeek has no native/json_schema structured output, but the output_schema-only agent still works via agno's prompt-based JSON fallback, so both paths produce a valid MovieScript.

Related test suites

• libs/agno/tests/unit/reasoning/test_reasoning_checkers.py and libs/agno/tests/unit/models/deepseek/test_deepseek.py: 79 passed (no network).
• libs/agno/tests/integration/models/deepseek/test_basic.py: 9 passed (streaming tests updated to be thinking-aware: in thinking mode the stream first delivers reasoning_content deltas before content deltas).

Notes

• tool_use.py, structured_output.py, reasoning_agent.py, thinking_tool_calls.py require optional cookbook dependencies (ddgs/yfinance) and were id-refreshed to V4; run them via the demo venv with those installed.
