Hi @Ilias_Efstathiou,

Here are the updates on the Gemini 2.5 Pro Batch API based on official sources and news:

1.Date of Arrival

  • Gemini 2.5 Pro launched in public preview on April 4, 2025 via the Gemini API in Google AI Studio, with Vertex AI support rolling out gradually .

  • General availability (including batch access) is expected by June 2025, aligning with scheduled release timelines .

2.Discount vs Real-Time API

Pricing for Batch API tokens (input/output) is the same as real-time:

  • For prompts ≤ 200k tokens:

    Input: $1.25 per million tokens
    Output: $10.00 per million tokens

  • For prompts >200k tokens:

    Input: $2.50 per million tokens
    Output: $15.00 per million tokens

There’s no extra discount for batch usage—they share the same pricing tiers.

3.Rate Limits

Rate limits for Gemini APIs—including batch and real-time are governed by:

  • Requests per minute (RPM)
  • Requests per day (RPD)
  • Tokens per minute/day (TPM/TPD)

These limits vary by usage tier:

  • Free Tier: Lower limits
  • Tier 1–3: Higher limits based on spend and account age

You can request upgrades or rate limit increases via the AI Studio dashboard once your project qualifies.
