Summary
Particle-1 scores 7.9 on AI BENCHY and ranks #146. It has 9.7 reliability, a 68.1% pass rate, $0.361 total cost, and 46.27s average response time.
What makes Particle-1 unique: It uses unusually many reasoning tokens, which can help explain its slower or more expensive runs.

Best estimate from public evidence; the vendor did not disclose every value. Particle AI describes Particle-1 as a token-efficient coding model post-trained on DeepSeek V4.1 Flash; no weights are released. Counts are inherited from the MIT DeepSeek V4.1 Flash base (748B total / 16B active); the open base does not make this API checkpoint open.

Cache prices apply to input tokens. Reads reuse cached prompts; writes store them and can cost extra. Output tokens use the output price.
Flaky tests
4
Flaky tests had mixed outcomes across runs (at least one pass and one fail).
